TeleCorder V 2.41-B-US 3
TeleCorder
Voice Logging Recorder — Model TCwL-B4
The TCwL-B4 TeleCorder can simultaneously record analog audio from up to four phone lines
or other line-level audio sources. Recordings start and stop automatically using either phone line voltage
sensing or audio activation. It has an internal hard drive where the most recent 11,000 hours of recordings
or 65,000 digital call files are stored. When the maximum capacity is reached, it continues documenting
new conversations by overwriting the oldest recordings.
While the TCwL-B4 records as a stand alone unit, connection to a PC using the supplied USB cable
and software (Win-98/XP/Vista-32) is required for initial set-up. Recordings are accessed via a PC using a
USB or LAN connection to the recorder for playback. Recordings can also be copied from the recorder to
your PC using the USB or LAN connections.
We recommend that all sections of this manual be read prior to installing the recorder. This manual
and the software supplied with the recorder are only for use with the TeleCorder model TCwL-B4.
Features include:
9Easy installation and administration
9Small footprint makes it easy to place in any location
9Internal 2.5" HDD capable of holding 11,000 hours of call data and up to 65,000 calls
9Search via Port #, Caller #, Dialed #, and Date
9Easy file conversion to standard .wav files
9User access to recordings and call data via USB and LAN (network)
9Master Recorder, Master LAN, PC LAN, and PC USB password protection of data
9Software can be installed on multiple PC’s
9Support for Ethernet (10Mbps) or Fast Ethernet (100Mbps)
9After the recorder is installed, it is always monitoring inputs and recording when activity is
present. The software does not have to be open on a PC for it to function as a recorder. The
PC software is only used for setup, playback of recorded conversations, searching calls, and
copying recordings to the PC. The TCwL-B4 recorder does not rely on the PC for recording.
9The recorder uses software on a PC as the interface to search and playback calls. If connected
to a network (LAN), the unit can be placed in an equipment room or a supervisor’s office to
prevent tampering. All that is needed is power, a connection to the network, and access to
the equipment you need to record — phone lines, telephone handset audio, two-way radio
audio, etc.

and +5vDC input jack for connecting to power using the supplied AC adapter.
2. Installing PC Software and Connecting to a PC (Win-98/XP/Vista-32)
Prior to connecting the recorder to your PC, install TeleCorder software onto your PC using the CD
included with your recorder.
2.1 Install Software onto the PC
Insert the included CD into the CD drive on your PC to
automatically install TCwL-B4 recorder software for Win-
98/XP/Vista-32 PC. If your PC is running older Windows
98, browse the CD using Windows file manager and
manually run the "SetupTeleCorder_V241_UsaEn-
W98_XP.exe" program.
If the recorder software is going to be installed on a
multiple user PC, the installation directory should be a
shared location or the “All Users” directory if you wish to
allow access by all of the PC users.
Follow the on-screen instructions. If your PC is
running Windows XP or Vista-32, you may be asked for a
Microsoft signature (screen shot at right).
* Be sure to select “CONTINUE ANYWAY”at the
security prompt *. Select continue until installation is finished.
After the recorder software has been installed, there should be an icon on the PC desktop as shown at
top left on page 5. If it does not automatically install the software, look at files on the CD using file manager
and install “SetupTelecorder.exe”software. If the PC will be used for configuring the recorder for LAN
access, install or copy the Reflash Utility file “TCwL_Reflash” from the software CD to your PC desktop
(icon at top right on next page). Follow the instructions in Section 5.1 for LAN setup using the Reflash
Utility.

TeleCorder V 2.41-B-US 5
The TeleCorder program will now be installed in your computer. It will be listed under
Programs, be listed in Control Panel add/remove programs, and if you also installed the
Reflash Utility there should be an icon on your desktop for the TeleCorder software (image at
left) and a Reflash Utility icon (image at right) for the program that is used to set up access to
the recorder via LAN (network).
For increased security and to prevent tampering via LAN, a USB cable connection to a PC is required
for administration of hardware settings. All hardware settings, such as the selection of voltage sensing or
audio activation (VAR), VAR sensitivity, VAR turn-off-delay, and VAR maximum call length, are done
only via USB. Network settings are done using the “Reflash Utility”.
2.2 Connect Power Supply and USB Cable
Plug the supplied 5 volt power supply (photo at right) into a standard 110v AC
outlet and connect its output cable to the DC+5V jack on the back of the recorder.
A blue LED on the front of the recorder will indicate that power is connected.
There are LEDs on the front of the recorder that will indicate recorder activity,
including one for each of the four channels.
Connect the supplied USB cable (photo lower right) from the USB port on the
back of the TeleCorder to a USB port on your computer. If the software was
previously installed, the first time you connect the TeleCorder to your computer
your PC should display a “New Hardware Found” message, search for and install
the required driver software (FT8U2XX_1.dll). Select “Continue” to install the
driver.
If connecting a TeleCorder to a PC that was previously used with a different TeleCorder product, you
have to remove the previous software and .dll files before connecting. Go to PC Start Menu > Control
Panel > Add or Remove Programs. Look for the .dll file name FTD2XXX and remove it. Then scroll
down to TeleCorder software and remove it. Now you are ready to install the new software and drivers.
You may receive a pop-up message telling you that it has “Found New Hardware, FT8U2XX_1.dll
device, installing Files Needed”, type the path to the folder where the driver was previously installed (such
as: C:\Program Files\TeleCorder\TeleCorder\TeleCorder.exe), or the path to the driver folder on the CD
supplied with your TeleCorder (such as: E:\Driver, where E is the CD drive on your PC containing the
TeleCorder CD).
3. Setup via USB Connection to PC
3.1 Open Software and run the TeleCorder program by clicking on the icon on your PC desktop
that was created when the program was installed or from the programs list if the icon is not on your desktop.
If more than one TCwL-B4 is found, select which one to access (maximum of four, one at a time).
3.2 Recording Process
When connected to standard telephone lines, the TeleCorder will automatically record the telephone
number calledin or dialed out, time duration of the call and the voices of the conversation.You don’t need
to change your procedure for making or receiving your calls. Nevertheless, the following points should be
considered.When connected to phonelines, channels should be set to start/stop recording using the voltage
sensing mode, not the VAR mode (hardware set-up from Hardware screen using a PC via USB
connection).
If Caller ID numbers are not displayed, confirm with your telephone company that your phone lines
have the caller ID feature enabled. Otherwise, there will not be caller phone numbers recorded and
displayed when managing the recordings. If you are connected to telephone handset audio, the recorder will
not show caller numbers and will only show dialed out numbers if the handset has standard DTMF tones
when dialing. Also check to be sure phone line channels are set for voltage sensing, not for VAR start/stop.
Always wait to answer a call until after the second ring so that the phone number from the calling party
can be received and stored with the recording.

6 TeleCorder V 2.41-B-US
When channels are set to start and stop recording using voltage sensing, outgoing calls will not be
saved unless they are longer than 8 seconds and contain a minimum of 3 dialed digits (DTMF tones). This
feature minimizes false recordings and does not apply when using Voice Activated Recording (VAR).
3.3 Setting for Phone Line or Voice Activated Recording (VAR)
When you first connect a new TeleCorder, default settings for all channels will be for Voice
Activated Recording (VAR). Channels connected to phone lines should have their start/stop mode changed
to the voltage sensing start/stop mode. In this mode, instead of monitoring audio levels, the recorder will
monitor for DC voltages on the selected inputs to indicate on-hook and off-hook status. The phone line
voltage is high when the circuit is not in use and will drop to a lower voltage when it is being used. Any
channels set for on-hook/off-hook voltage sensing that are not connected to a phone line will not show any
recordings due to the lack of the DC voltage changes that are required to initiate a recording in this mode.
If you connect any of the TeleCorder inputs to audio sources that do not have standard on-hook/off-
hook voltages, these channels must be set for audio or voice activated recording (VAR).
3.4 VAR Settings (Voice Activated Recording)
Recorder channels set for the VAR mode will detect the voice level on the line to start a recording. It
will start recording when a preset audio level is reached (normal conversation levels), and stop after the
audio drops below this threshold (no sound other than weak background noise) for a preset period of time.
The length of quiet required for the recording to end is called “turn-off-delay”.
Phone Line Recording Voice Activated Recording (VAR)

on the PC.
3.6.2 Date/Time Setting: Click on this box to copy the date/time setting from your PC to the
TeleCorder.
3.6.3 Set Channels to VAR mode instead of voltage sensing mode used for phone line:
Each channel (Port) in the recordercan be set to start and stop recording using either audio activation (VAR)
or voltage sensing. Channels showing a check mark in the boxes labeled Port 1, Port 2, Port 3, or Port 4,
are set for VAR recording. Channels with no check mark indicate they are set for phone line recording. For
any channel you want to start/stop recording using the phone line voltage sensing mode, click on the box
for that channel to remove the check mark, then click the Write Hardware button to confirm any changes.
3.6.4 VAR Voltage Threshold: Set the threshold level to match the audio level on your audio source.
L0: Extra Sensitive, suitable for weak audio sources with low background noise level: (for
example, with weak earphone or line-out recording).
L1: High Sensitivity, suitable for normal line level audio sources with low background noise
levels: (normal phone handset earpiece audio or weak speaker of radio).
L2: Mid Sensitivity, suitable for higher than normal audio levels and/or higher background noise
levels: (for recording from a noisy phone line when voltage sensing cannot be used due to non-
standard voltages or with normal speaker audio from a radio).
L3: Low Sensitivity, suitable for very high audio levels, and high background noise levels.
Recording may stop if audio levels are too weak: (phone recording with non-standard and very
noisy DC voltages, or extra loud radio audio).
After making changes, click the button labeled Write Hardware to confirm any changes. You may be
asked to quit the program and try again. You may also need to un-plug and re-connect the TeleCorder
power or USB cable to successfully change the TeleCorder operating parameters.
3.6.5 VAR Turn Off Delay: If any channels have VAR selected for recording start/stop, also select one
of the four turn off delay options (VAR Turn Off Delay): 4, 12, 32 or 100 seconds. This setting will help to
prevent recordings from ending during quiet periods. Click the Write Hardware button to confirm any
changes.
3.6.6 VAR Time Out: If any channels have VAR selected for start/stop, set the time out to one of the
four choices: 20, 40, 60 or 80 minutes. This setting will limit the maximum length of a recording for easier

management of long conversations or for when recording from broadcast radio where pauses may not be
long enough to separate individual recordings using VAR for start/stop. If a recording reaches the
maximum length of time that you select for VAR Time Out, that recording will end, and a new recording on
that channel will begin. Click the Write Hardware button to confirm any changes.
3.6.7 Save VAR and Outgoing Calls Less than 8s or Outgoing Calls with Less than 3
DTMF Codes: Click on this option to place a check mark in its box if you want to save recordings that
are less than 8 seconds long. If this box is not checked, VAR recordings shorter than 8 seconds, and
outgoing telephone calls (using voltage sensing for start/stop) with less than 3 DTMF digits, will not be
saved.
This setting is normally used if external noise causes frequent and unwanted false audio activated
recordings,or if telephone line testing producesshortoff-hook conditionsthat are not associated with actual
phone line usage. It is normal torecord all activity on the monitored circuits. Usecare when setting to delete
short recordings.
3.6.8 Audio Recording Mode: From this sub-button you can set the quality of recordings.
Mode 0 --- Large file, good audio.
8bit linear PCM mode.

3.6.9 Limitation for List Displaying: From this sub-button, you can set the list display features to
speed up the list refresh process or to have more items displayed in the lists of recordings shown on your
PC in the main TeleCorder program screen. The default setting is 2000 for fastest speed. You can select a
different number, such as 10000, 32768 or 65536, respectively. This selection is saved in software, not as a
hardware setting and will be reset to 2000 when the software is closed and reopened.
3.6.10 Caller ID Detection Settings:From this sub-button you can set (turn on/off) the caller ID
detection features.
Pre-Ring DTMF Detection:If the local caller ID mode is DTMF and sent before the ring, you
must turn this feature on. Otherwise, if erroneous caller numbers are
sometimes received, you should turn this feature off.
Pre-Ring FSK Detection:If the local caller ID mode is FSK and sent before the ring, you
must turn this feature on. Otherwise, if erroneous caller numbers are
sometimes received, you should turn this feature off.
Forced FSK Between Rings:If your caller ID signaling is FSK and sent between the rings,
you must turn this feature on. This is the normal setting for North America.
3.6.11 About TeleCorder PC S/W: From this sub-button, you can see additional information about
the software supplied with the TCwL-B4 recorder.
3.6.12 QUIT: Use this sub-button to exit the Hardware Information & Settings window.
3.6.13 NOTES:
1. The above settings must be locked into the TeleCorder hardware by restarting the
recorder. After any of the above settings are changed, they will not take effect until the
recorder is restarted by turning off or disconnecting AC power to the TeleCorder, waiting
a minimum of ten seconds, and powering the TeleCorder back on. Any changes made in
software should now be locked into the recorder’s internal memory.
2. To avoid interruption of active recordings, you should only set the above items while the
recorder is idle. Wait until no channels are active or unplug inputs prior to changing settings.
3. After the settings have been changed, check to make sure that the recorder is functioning
as expected.

TeleCorder V 2.41-B-US 9
4. Therecorder listens foroutgoing numbers dialed using DTMF/touch-tone signaling and stores
them with the recording. It is possible for it to document and record false phone numbers when
the recorder is in the VAR mode (particularly when recording broadcast radio music where the
audio can mimic sounds of dialing). To avoid collecting and recording these erroneous numbers,
you can use the PC interface to disable storing of dialed digit signaling.
4. Connecting to Phone Lines and other Audio Sources
TeleCorder inputs require 2-wire analog audio such as from direct connection to analog phone lines,
two-way radios, amplified microphones, telephone handset or headset audio (analog or digital phones,
using direct connection to earpiece audio or optional TSA-3LM or TSA-SLM adapters), etc.
The TeleCorder connects in parallel to your audio sources. There are two modular phone jacks on the
back labeled PHONE. Each modular phone jack has connections for two phone lines or other audio sources.
When looking at the back panel, the jack on the left is for Ports 1 and 2, the jack on the right is for Ports 3
and 4. The modular jacks use pins 3 & 4 for the first
input (center pair), and pins 2 & 5 for the second
input (see the drawing at left). Each individual
input can be referred to as either a Channel or Port.
Connect audio sources for channels one and
two using the left jack, and channels three and four
to the right jack in a similar manner.
The TCwL-B4 is supplied with two of the MTJ-
S2 splitters (see photo at right) to provide
individual jacks for each input if you are not using
phone cables with two lines. Four T-18 cables sets (18' phone line cable with
“T” adapter, photo at left) are also supplied with the
recorder. You can use these or other suitable cables to
connect to your phone lines or other audio sources to
the recorder.
If it is not convenient or possible to install using
standard modular jacks, identify the pair of wires for
each line or audio source and connect in parallel to
each individual input on the TeleCorder.
With bundled phone wiring, you must first identify the line pairs among the wiring cables and then
connect the wires from the TeleCorder inputs to these pairs. Equipment and wiring diagrams may be
required to expedite proper installation. Check with your phone or wiring provider for assistance as needed.
If you wish to record from multiple line analog phones or digital telephone sets, instead of individual
phone lines, the most popular way to connect is with a handset splitter. The handset splitters (such as the
Omnicron TSA-3LM, TSA-2A1, or TSA-SLM) are available from your TeleCorder representative. Your
sales representative can also assist you in selecting other cables or adapters to simplify installation for your
application.
5. Setup for Accessing the TeleCorder via LAN
After installing the TeleCorder software onto a PC, use the software to configure the recorder,
connecting the recorder to your phone lines or other sources of conversations and confirming that it
is functioning properly. You are ready to use the Reflash Utility to setup access to the recorder from
a network (LAN).
Connect the LAN cable to a network switch or to the LAN port on the back of your PC and
then to the LAN port on the TCwL-B4. Check to see that the cable connection indicator (RED) LED
and activity (GREEN) LED are lit on the back of the unit. Then proceed to run the Reflash Utility.

10 TeleCorder V 2.41-B-US
5.1 Reflash Utility Application to Find or Change IP Address
With the recorder connected to your network or LAN port on a PC, open the “TCwL_B4”Reflash
Utility that was installed onto your PC earlier (Section 2.1) to find the unit on the network connection. The
initial IP of TCwL-B4 is set as "192.168.0.200". If the IP segment of your network is within the same range
(“192.168.0.*”) it should be found by your PC. Be patient, this may take some time (many seconds). If
more than oneTCwL-B4 recorder is connected tothesame LAN, theIP addresses must be different.
Select Find the Device Over the LAN. It will display the factory set
IP address on the screen when it is found by the Reflash Utility application.

TeleCorder V 2.41-B-US 11
If the TCwL-B4 cannot be found via the LAN, the IP address of the unit can be entered into the
“Connect Directly Using Above IP” box to search for the specific IP address. If your IP address range is
within the default range of the unit you will not need the USB connection to access the TCwL-B4.
If the TCwL-B4 cannot be found via the LAN, connect a USB cable between a PC and the back of the
TCwL-B4 recorder, then run the Reflash Utility (V1.3) and edit the device settings. When finished, be sure
to click on the Change Device Settings button. To lock the new settings into memory, power must be
cycled (power the recorder down and up).
When done, disconnect the USB and run the Reflash Utility again. When the Reflash Utility finds the
device, you are ready to run the TeleCorder software and access the recorder via the LAN connection.
When the Reflash Utility V1.3 is open and the device is found over the LAN, port settings can be
changed using the Reset by IP command. Find the device over the LAN, make your setting changes, select
the “Reset by IP” button then select the “Change device Settings as wanted” button. Close the SW and
reopen to verify changes.
5.1.1 Reflash Utility Application Notes (Version 1.3)
TCwL-B4 can be connected via USB or LAN. The utility will check TCwL-B4 from USB at boot stage
automatically (first). If no USB is detected, you can force it to search TCwL-B4 over the LAN via the Find
the Device Over the LAN button. The device default IP will have to be within the same range as the
network for this to work.
The Direct IP input field for direct connection and setting can be used if the device is not found over the
LAN. Enter the IP and select find.
If you have a problem reading the device, you may check the right-bottom corner box to Load default
settings file (factory defaults).

6. Using the TeleCorder
6.1 Managing and Playing the Recordings with a PC
Double click on the TeleCorder software icon to open the program. The software will search for a
TCwL-B4 recorder connected to the PC via USBor LANand, if arecorderis found,the software window will
display the most recent 2,000recordings.TheTeleCorder recorder software can only connect to one recorder
at atime, LAN or USB. If more than one TCwL-B4 is found, select which one to access (maximum of four).
The PC does not have to be ON or connected to the TeleCorder for it to function. Connecting the
TeleCorder USB or a LAN cable to your PC and/or turning the PC power on or off will not stop the
recorder from functioning. You can also disconnect the TeleCorder USB and or LAN cable from a PC
and connect it to a different PC or LAN connection without interrupting the TeleCorder operation. The
PC used for managing/playing must be equipped with an available USB or LAN port, sound card as
well as speakers, and use Windows® operating system Win-98/XP/Vista-32.
6.1.1 Using the Utility Software:
You must install the supplied utility TeleCorder Manager/Player software from the provided disk
to your computer prior to being able to manage the recorder from the PC or play recordings through the
PC control (see manual Section 2). The first time that you connect your PC to your TeleCorder, you
may be asked to install the USB device driver. This driver should have been copied to your PC during
install. If not, use the CD supplied with your TeleCorder to install the required USB driver following
the instructions displayed on your computer.
After installing the software, place a short cut icon on the desktop for easy access (if it was not
automatically installed during install). Click the software icon, or the short cut created during the install,
and the recordings will be listed in the main window (as shown in the following screen image). The listed
information includes the ITEM or sequential recording number, the PORT that was the source of the
recording, CALLER # (if available when the recording was made) or DIALED # (if available when the
recording was made), DATE (mm-dd-yy) of each recording in month, day, and year, TIME the recording
started, and the DURATION of each recording in minutes and seconds.
All records are listed inthe reverse order so that the most recent recording is indexed as item number 1.
You can drag the slider bar on the right side of the display window to view the un-displayed part of
the list. On the lower part of the form, there are buttons for Refresh, Re-Order, Find, Files, Info & Settings,
Security, and Exit. The recorders IP address will be displayed in the top of this window.

TeleCorder V 2.41-B-US 13
These buttons provide the following functions:
6.1.2 Refresh: Refresh the list to display the latest recordings in the TeleCorder at any time.
6.1.3 Re-Order: User can select one of the following ordering rules to re-order the list.
1. Recorded – provides a list based on the time recordings ended.
2. Starting Time – provides a list based on the time recordings started.
3. Record Duration – provides a list based on the length of recordings.
4. Channel Number – provides a list based on the channel number.
5. Un-Answered List – provides alist ofcallson phonelinesthat were notanswered.
(Un-Answered Listing is not supported with TCwL-B4)
6.1.4 Find: You can search the records using a specific port/channel number, caller number or dialed
number and/or within a date range that you input.
In the dialogue box, you can enter search conditions such as date range, digits from a phone number
such as 010, 6256, etc. The searched results will display on the screen after you select “Start Search”.
You may also enter only a start and stop date range and all of the recorded items during the date range
will be displayed.
The recorded items after a search can be played or used for further searching and for making Wave
files in a batch job. Refer to the File Copy for more details.

14 TeleCorder V 2.41-B-US
6.1.5 Files: This button provides the following functions for the displayed files.
6.1.5.1 Conversion of Recordings to WAVE Files and Saving to PC:
Wave Files are a widely used and supported multimedia File Format for the PC and other computer
systems. Since the TeleCorder uses a unique format for saving the recordings in digital form, digitally
converting them is a better way to exchange information with other systems that do not have TeleCorder
software. You can use your PC to send audio recordings via e-mails or make backup CDs without worrying
that others may not be able to play them.
There is also an option to save individual recordings when they are selected for playback. Select the
button with red dot “Q” from playback menu, see section 6.2.
6.1.5.2 Browse --- Use the Browse button to select the folder on your PC hard drive where you wish to
save the copies of the recordings.
6.1.5.3 All --- Copy all of the records listed in the form, including both the ones displayed and the ones
not displayed. This button would be used to copy all recordings retrieved by a search.
6.1.5.4 Last Month --- The software will search again from all of the records in the TeleCorder within

TeleCorder V 2.41-B-US 15
the 1st and 31st of last month, then perform a batch job to generate the wave files. This function is specially
designed for users to make monthly backups.
6.1.5.5 Last Week --- The software will search again from all of the records in the TeleCorder within
the last week, and then it will do a batch job to generate the wave files.
6.1.5.6 Help --- Producesawindow with more detailed information aboutconverting to wavefiles.
6.1.5.7 Use exclusive fast mode if possible --- Use this button to speed up the file conversion
process.
6.1.5.8 File Range --- Use this button to
select a range of files that will be converted to
wave files from the list of calls. For example,
files numbered between 1 and 100. Select RangeGo button to see details on file conversion and save
process prior to selecting “OK” to start the process.
All the generated files will be placed in the file folder you select in the window left of Browse button.
After the files have been converted and saved to your PC the list of calls on the TeleCorder Recording
List will show only those files and need to be refreshed to show all calls.
Each file refers to a unique record. The name of each file contains date and time of the call, caller or
dialed number such as File P2 10-26-08 09=11=10 DIAL TO 18609280377.WAV (recording made on
TeleCorder Port 2on October 26th, 2008 at 09:11:10, call was outgoing and dialed to 1-860-928-0377).
The files are suffixed with “.WAV”. You can change the file names as required, but you should not change
the suffix unless there are special requirements.
6.1.5.9 Volume Balance Setting (DAVA): Digital Automatic Volume Adjustment capabilities. This is
done in software, not hardware. If the volume levels of the 2 sides of a conversation are different, or if the
line quality is not well adjusted, the Digital Automatic Volume Adjustment (DAVA)) function will amplify
the lower or far side to more closely match the level of the stronger or near side of a recorded conversation
during playback. Since background noise will also be amplified together with the sound, there will be a
compromise to permit weak voices to be played at higher levels without raising background noise levels
to objectionable levels. There are 2 possible settings.
USE DAVA (auto volume adjustment) for Volume Balance: This setting is normally used to
enable DAVA when converting single files or batches of files to wave
files. It provides a medium amount of boost for weak audio.
Deeper DAVA Mode (may have more noise): This setting provides a higher level of boost to weak
audio but may also increase weak background noise levels.
6.1.5.10 Print and Save the List of Records: The displayed list on the screen can be printed or saved
into a “.txt” file. No matter how the call list is re-ordered, the searched and sorted list can be printed.
6.1.5.11 Delete Recordings: The recorded calls can be selectively or entirely deleted. To avoid
unauthorized deletion, the password must be entered before deleting recordings. If no password has been
set, you will need the master password that was supplied with your TeleCorder. Options are to delete the
most recent recording, all recordings, or a selected range of recordings. Deleted recordings cannot be
recovered. Un-answered is not supported with TeleCorder model TCwL-B4.
From Delete Item(s) box click on Select Range button and follow screen messages to select which
recordings you wish to delete from the recorder’s hard drive. After selecting which recordings to delete,
you will be provided with an option to Confirm: Files are deleted as desired?. Follow on screen
instructions to recover the recordings as needed. If file recovery is selected, recovery will take place when
TeleCorder software is closed and re-opened. Recordings made after selecting recovery and re-opening the
software will be permanently lost.
6.1.6 Info & Settings: Use this button to access the recorders hardware and information settings. See
Section 3.6 for additional information on configuring the various settings for your application.

6.1.6.2 Date/Time Setting: From this sub-button you can read and set the real time clock in the
recorder.
6.1.6.3 Set Channels to VAR Mode Instead of Voltage Sensing Mode used for Recording
from Phone Lines: Each channel (Port) in the recorder can be set to start and stop recording using either
audio activation (VAR) or voltage sensing. Channels showing a check mark in the boxes labeled Port 1,
Port 2, Port 3, or Port 4, are set for VAR recording. Channels with no checkmark indicate they are set for
phone line recording. For any channel you want to start/stop recording using the phone line voltage sensing
mode, click on the box for that channel to remove the check mark, then click the Write Hardware button to
confirm any changes.
6.1.6.4 VAR Voltage Threshold: Set the threshold level to match the audio level on your audio source.
L0: Extra Sensitive, suitable for weak audio sources with low background noise level: (for
example, with weak earphone or line-out recording).
L1: High Sensitivity, suitable for normal line level audio sources with low background noise
levels: (normal phone handset earpiece audio or weak speaker of radio).
L2: Mid Sensitivity, suitable for higher than normal audio levels and/or higher background noise
levels: (for recording from a noisy phone line when voltage sensing cannot be used due to non-
standard voltages or with normal speaker audio from a radio).
L3: Low Sensitivity, suitable for very high audio levels, and high background noise levels.
Recording may stop if audio levels are too weak: (phone recording with non-standard and very
noisy DC voltages, or extra loud radio audio).
After making changes, click the button labeled Write Hardware to confirm any changes. You may
be asked to quit the program and try again. You may also need to un-plug and re-connect the TeleCorder
power or USB cable to successfully change the TeleCorder operating parameters.

one of the four turn-off-delay options (VAR Turn Off Delay): 4, 12, 32 or 100 seconds. This setting will
help to prevent recordings from ending during quiet periods. Click the Write Hardware button to confirm
any changes.
6.1.6.6 VAR Time Out: If any channels have VAR selected for start/stop, set the timeout to one of the
four choices: 20, 40, 60 or 80 minutes. This setting will limit the maximum length of a recording for easier
management of long conversations or for when recording from broadcast radio where pauses may not be
long enough to separate individual recordings using VAR for start/stop. If a recording reaches the maximum

TeleCorder V 2.41-B-US 17
length of time that you select for VAR Time Out, that recording will end, and a new recording on that
channel will begin. Click the Write Hardware button to confirm any changes.
6.1.6.7 Save VAR and Outgoing Calls Less than 8s or Outgoing Calls with Less than 3 DTMF
Codes: Click on this option to place a check mark in its box if you want to save recordings that are less
than 8 seconds long. If this box is not checked, VAR recordings shorter than 8 seconds, and outgoing
telephone calls (using voltage sensing for start/stop) with less than 3 DTMF digits, will not be saved.
This setting is normally used if external noise causes frequent and unwanted false audio activated
recordings,or if telephone line testing producesshortoff-hook conditionsthat are not associated with actual
phone line usage. It is normal torecord all activity on the monitored circuits. Usecare when setting to delete
short recordings.
6.1.6.8 Recording Quality: From this sub-button you can read or set the quality of recordings.

6.2 Play Recordings from List: To play a recording using your computers media player and
speakers, select a file using your PC mouse and click on it. Large files may take a few seconds prior to
opening. When playing recordings, buttons in the lower part of the screen will be swapped to a new set of
buttons that are used to control various playback functions, as shown in the following image. If it is a long
recording, the playback function buttons will not show until the recording has been completely transferred
from the TeleCorder to the PC.
The functions of these buttons are:
aVa1 &aVa2:The aVa buttons or “digital audio volume adjustments” are used to equalize unbalanced
audio. While it will attempt to balance a call when there is difference in audio levels, it may not be able to
bring extremely weak audio up enough to balance it. These volume adjustments only work in playback.
Click the aVa1 button and the recorded audio will be processed and played from the beginning with a
medium level of Automatic Volume Adjustment. Click the aVa2 button and the recorded audio will be
processed and played from the beginning with a higher level of Automatic Volume Adjustment. You may
also drag the horizontal slider bar to move the playback start point.
Record ●:The record button is used to convert the current highlighted call or calls you are playing to
a wave file and save it to your PC. These .wav files can be burned to a CD and played in most players. The
recordings will be saved by default with a file name containing port
number, date and time of the call, and caller ID or dialed numbers.
There will be an option to rename the file when converting to a wave
file.
Fast Reverse <<:Skips backward to replay a portion of a call.
Pause II: Used to temporarily stop a recording with the ability
to resume listening where stopped.
Fast Forward >>: Skips forward to find a location in a call.
Stop ■:Stops the recording and returns to the beginning of the call.
Go to next:When a check is placed in the Go to next box, after a call has finished playing it will
automatically go to the next call and start playing it (useful when playing radio files with receive and
transmit audio in separate files).
