Notes on Chip Component Replacement
•Never reuse a disconnected chip component.
•Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
ICD-BM1/BM1PRO
•UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with
the lead free mark due to their particular size.)
: LEAD FREE MARK
Unleaded solder has the following characteristics.
•Unleaded solder melts at a temperature about 40°C higher than
ordinary solder.
Ordinary soldering irons can be used but the iron tip has to be
applied to the solder joint for a slightly longer time.
Soldering irons using a temperature regulator should be set to
about 350°C.
Caution: The printed pattern (copper foil) may peel away if
the heated tip is applied for too long, so be careful!
•Strong viscosity
Unleaded solder is more viscous (sticky, less prone to flow)
than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.
•Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may
also be added to ordinary solder.
Flexible Circuit Board Repairing
•Keep the temperature of the soldering iron around 270°C during
repairing.
•Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
•Be careful not to apply force on the conductor when soldering
or unsoldering.
*Replacement of IC601, IC702 used in this set requires a special
tool.
•The voltage and waveform of CSP (chip size package) cannot
be measured, because its lead layout is different from that of
conventional IC.

B Getting Started
Step 1: Installing the Batteries
1 Slide and lift the battery compartment lid.
2 Insert two LR03 (size AAA) alkaline batteries with correct
polarity, and close the lid.
Clock setting display appears when you insert batteries for the first time or
after the unit has been without batteries for a certain period of time.Please
refer to steps 3 to 6 in “Step 2: Setting the Clock” on pages 8 and 9 to set
the date and time.
Using on house current
Connect the AC power adaptor AC-E30HG (not
supplied) to the DC IN 3V jack of the unit and to
the wall outlet.Do not use any other AC power
adaptor.

Getting Started
Replacing the Batteries
The battery indicator on the display window shows the battery condition.
Notes
• Do not use manganese batteries for this unit.
•When you replace the batteries, insert the new ones within 3 minutes after you
remove the exhausted ones.Otherwise, the display may show the clock setting
or incorrect date and time when you re-insert the batteries. In this case, set the
date and time again.The recorded messages and alarm setting, however, will
remain.
• Do not charge dry batteries.
•When you are not going to use the unit for a long time, remove the batteries to
prevent damage from battery leakage and corrosion.
Battery remain indication
: Replace both of the two batteries with new ones.

do not remove the “Memory Stick”, batteries,or
the AC adaptor (not supplied). Doing somay
damagethe data.
Notes
•The unit starts accessing the data after it is turned on.
•If the unit is required to processexcessiveamount of data, “MEMORY STICK
ACCESS“may be displayed for an extended period of time. This is not a
malfunction of the unit. Wait until the messagedisappears.
Removing the “Memory Stick”
Make sure that “MEMORY STICK ACCESS“ disappears, and turn off the
unit. Then open the “Memory Stick” slot cover and push the “Memory
Stick” into the slot, so that the “Memory Stick” pops out.

Reviewing the recording
Slide the control key to B.SPACE. You cansearchbackwards while

playback startsfrom that point. You can add an overwrite recording from
that point.
Monitoring the recording
When recording, you can connectan ear receiver supplied or not supplied
to the i(headphones) jack and monitor the recording from the connected
ear receiver.You can adjust the volume withVOL +/–, but the recording
level is fixed.
Note
If you turn up the volume excessivelyor place the earreceiver nearthe
microphone while monitoring recording, the microphone may pick up the
sound from the ear receiver, causing acoustic feedback (howling sound).
Starting recording automatically in response to the sound
— Advanced VOR function
Slide the VOR (voice operated
recording) switch to ON during stop or

detected,and “VOR PAUSE” appears.
Notes
•Recording will not be started unless the control key is setto REC.
•VOR function is affected by the sound around you. Set the MIC SENS
(microphone sensitivity) switch according to the recording conditions. If
recording is not satisfactory after you have changedthe microphone
sensitivity, or for important recording, setthe VOR switch to OFF.

device you use,connectthe IC recorder asfollows. For available
accessories,consult with your nearestSonydealer.
Recording with an External Stereo Microphone
Connect an external stereomicrophone to the MIC (microphone) jack. You
canenjoy the stereorecording by using a stereomicrophone.
When you connect an external microphone, the built-in microphone is

Notes
• When the audio recording level is large, sound may be recorded
interrupted if you use an audio connecting cable without register. Use a
registered audio connecting cable.
• When the audio recording level is small, do not use a registered audio

You can go back approximately 3 seconds by pressing the jog lever down
(.) once, or advance approximately 10 seconds by pressing the jog lever
up (>) once.This function is useful when locating a desired point in a

you can play back a message repeatedly.
Slide the control key to PLAY.“MSG.REPEAT“
will be displayed and the selected message will be
played back repeatedly.

Erasing Messages
You can erase the recorded messages one by one or all messages in a folder
at a time.
Note
Once a recording has been erased, you cannot retrieve it.
Erasing Messages one by one
Be sure to erase unnecessary messages only.
When a message is erased, the remaining messages will advance and be
renumbered so that there will be no space between messages.

stop mode.
“ERASE?” will flash while the first and last 5
seconds of the message are played back 10
times.
2 Press ENTER while the message is being
played back and “ERASE” is flashing.
The message is erased and the remaining
messages will be renumbered.(For example, if
you erase Message 3, Message 4 will be
renumbered as Message 3.When erasing is
completed, the unit will stop at the current
position.)
To cancel erasing
Press CANCEL before step 2.
To erase other messages
Repeat steps 1 and 2.
To erase a message partially
First divide the message (see page 31) and then follow the steps on this

Erasing All Messages in a Folder
You can erase all recorded messages in a folder.
1Select the folder containing the messages you want to erase.
For information on selecting a folder, see step 2 of "Recording
Messages" on page 13.
2While pressing FOLDER, press ERASE for
more than 1 second.
“ERASE ALL?” will flash for 10 seconds.
If no messages are recorded in a folder

Formatting a “Memory Stick“
You can format a “Memory Stick“ using the Memory Stick IC Recorder.
Formatting will delete all data recorded in the “Memory Stick“ including
images and other data. Before formatting, check the data in the “Memory
Stick“.
Because a commercially available “Memory Stick“ has already been
formatted at the factory, you do not need to format a “Memory Stick“
before the first use.
The supplied “Memory Stick“ has also already been formatted.

Press ENTER again.
Formatting starts.
“FORMATTING” will be displayed on the
display.
After formatting, the display in step 2 will

7 Press MENU to exit the menu mode.
The window will return to the normal display.
After formatting, three folders are automatically made in the “Memory
Stick“ (This is the same after inserting a “Memory Stick“ for the first
time.)
To cancel formatting
Select “NO“ in the step 4 or press CANCEL while “OK ?“ is displayed in
step 5.
Note
You cannot format when the write-protect switch on the “Memory Stick“ is set
to “LOCK”.
