REGULATORY INFORMATION
About Telephone Call Recording
Federal Law in the USA requires that at least One Person involved in a conversation be
aware that a call is being recorded.
In addition, many States in the USA require that All Parties in a conversation be aware that a
call is being recorded.
All Federal and State legislation relating to the recording of Telephone Calls over the
Telecommunications network should be adhered to by the user of this equipment.
Accepted forms of notification recording by a telephone company
The Federal Communications Commission defines accepted forms of notification for
telephone recording by telephone companies as:
 Prior verbal (oral) or written notification of all parties to the telephone conversation.
 Verbal (oral) notification before the recording is made. This is the most commonly used type.
 An audible beep tone repeated at regular intervals during the call.
CRU3 does not provide automatic ORAL notification. You must do so manually before
commencing your Call Recording.
Optional Feature
CRU3 is available with an Optional Facility (extra cost) that will Automatically generate and

DESCRIPTION
Our Model CRU3 CALL RECORD UNIT is a cost effective Personal Telephone Call
Recording facility, for users that only need to Record Specific Telephone Conversations.
It is used in conjunction with a Laptop or PC, where it operates with the SOUND CARD fitted
within the Laptop or PC.
Our easy to use CRS PC software program is provided with CRU3, to allow you to Record
Telephone Calls as required and save them as MP3 files or WAV files in a nominated folder.
CRU3 can be connected to ANY telephone handset including those used with ALL PBX, VOIP
or Residential telephones. It can also be used in conjunction with a headset that is connected
by cable to a Telephone.
Telephone Call Recordings are STARTED and STOPPED, by clicking the RECORD
icon and STOP icons on the supplied CRS software. Your recordings ‘or files’ can be
individually named, auto-named or stored by time and date, in a nominated folder
located on a local or networked drive.
Recorded calls are saved in MP3 format, which minimizes memory usage and facilitates
easy replay, storage and email transfer. Your MP3 Recordings can then be replayed
through your normal PC Music Player, emailed or archived to a permanent storage
medium.
WINDOWS 7, 8 or 10 USERS
If you are using Windows 7 (or later versions), changes made by the Windows operating
system will require you to change the default folder that your call recordings are stored to,
after installation of the CRS software.
You can change the record folder to any other folder on a local PC or Network. See page 14
for details.
If the Default Folder is not changed, recordings will still be saved, but they will be saved to a
destination other than the designated Default Folder.
WINDOWS XP USERS
If you are using Windows XP (or earlier versions), you can use the default folder or you can
change the record folder to any other folder on your PC or Network.

NATCOMM Page 13
You are provided with a choice of 3 pre-configured ‘Sampling and Save’ settings, for saving
your recorded call.
High Quality samples and saves files with the Highest audio quality, (not necessary for phone
calls) and uses the most memory.
Medium Quality samples and saves files with very good quality, using a moderate amount of
memory (usually not necessary for phone use)
Standard Quality samples and saves files with a sampling rate which produces GOOD
quality for most TELEPHONE LINE applications and uses the least amount of
memory.
‘Sampling Rate’ is a term which describes the frequency that a sampling of audio is taken
during the record period and saved. The more frequently this is done, the higher the quality of
the recording, but the more memory used.
The DEFAULT SETTING for CRS is STANDARD QUALITY.

TROUBLESHOOTING AUDIO PLAYBACK
If your cannot hear ANYTHING or the volume needs adjusting:
a) Open ‘Windows Mixer’.
b) Adjust the slide bars for Volume and Line In (or Mic) until the correct level is
achieved.
c) Deselect any Mute settings that are ticked.
If you can only hear YOURSELF:
You need to exchange the telephone cable that connects into the HANDSET
CONNECTION port of your CRU3
This is because there are TWO different wiring configurations used in curly cord handsets
and the handset you are using uses the less common configuration.
One supplied cable is Black and has a white coded band on one end (this is the normal
cable). The other does not. You will need to use the alternative e supplied cable.

GENERAL TROUBLESHOOTING
ENSURE YOUR SOUND CARD AND SPEAKERS ARE WORKING CORRECTLY BY
TESTING WITH ANOTHER SOUND APPLICATION
The vast majority of PC based Recording installations take place without problem. On rare
occasions, due to the wide range of sound cards available, problems can be experienced due
to incompatible software settings within the sound card control software.
If you experience problems with your sound card, call ph [phone] for assistance.
CRS SOFTWARE FAILS TO START RECORDING
*
Ensure that the supplied PC cable is correctly connected to your PC’s SOUND CARD and that
the other end of this cable is correctly connected to the PC port of your CRU3 device.
*
Ensure that your CRS software has detected the correct COM port and that it is displayed on
your CRS menu (see page 8).
FILES ARE RECORDED BUT ARE SILENT
Ensure that you have correctly selected LINE IN or MIC as your input source (see page 9).
Move the REC slide bar on the CRS menu towards MAX until the required record level is
obtained (see page 10).
USING the MIC input instead of the LINE IN input.
The MIC input provides a much higher input level to your sound card than the LINE input.
As a result, the recorded volumes will be much higher.
You will need to REDUCE the input volume setting
on the slide bar of your software (or the MIC setting in
Windows Sound Mixer).

NATCOMM Page 19
OPTIONAL RECORDING TONES
It is an offence to record a telephone call without One or Both parties agreement.
Please refer to the information on page 2.
CRU3 can inject ‘recording tones’ into the telephone call, as per the (FCC) Federal
Communications Commission recommendations.
If you wish to inject recording tones into the telephone call during recording, you will need to
have a SPARE USB port on your PC and you should purchase CRU3 with this extra charge
option.
Once the alternative cable is connected to CRU3 and connected to a USB port, then CRU3
will inject a Recording Tone into your telephone handset at intervals of 15 seconds, whenever
calls are being recorded.
A small slide switch located next to the power input is used to Enable or Disable these
recording tones.
To ENABLE the injection of call recording tones when recording calls, you should set your
Slide Switch to the Right Hand side.
To DISABLE the injection of call recording tones when recording calls, you should set your
Slide Switch to the Left Hand side.
