 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.

BGetting 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.
If the battery compartment lid is
accidentally detached,  attach it
as illustrated.
Clock setting display appears when you insert batteries for the first time,
or when you insert batteries after the unit has been without batteries for a
certain period of time. Please refer to Steps 2 to 4 in “Step 2: Setting the
Clock” on pages 8 and 9 to set the date and time.

Replacing the batteries
The battery indicator on the display window shows the battery condition.
When 
 flashes, replace the batteries with new ones.
When 
 flashes, the batteries are exhausted and the unit will stop
operation.
Battery life*
With continuous use, approx. 7.5 hours (SP)/15 hours (LP) of recording or
approx. 6 hours (SP)/8 hours (LP) of playback is possible.
* Using Sony alkaline batteries LR03 (SG)
* When playing back through the internal speaker with VOL control at around 4
The battery life may shorten depending on the operation of the unit.
Notes
• Do not use manganese batteries for this unit.
• When you replace the batteries, insert the new ones within 3 minutes after you
removed the exhausted ones. Otherwise, the display may show the clock
setting display 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.
• When replacing the batteries, be sure to replace both batteries with new ones.
• 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.
Note on the 
ACCESS
 message
When you insert the batteries, “ACCESS” may appear on the display window.
Do not remove the batteries while this message is displayed.
If the unit is required to process excessive amount of data, “ACCESS” may be
displayed for an extended period of time. This is not a malfunction of the unit.
Wait until the message disappears before starting operation.

BBasic Operations
Recording Messages
You  can record up to 99 messages in each of three folders (A, B, or C) for
ICD-B10 or five folders (A, B, C, D or E) for ICD-B15. Since a newly
recorded message is automatically added behind the last recorded
message, you can start recording quickly without searching for the end of
the last recording.
Note
Before making a long recording, be sure to insert new batteries and check the
battery indicator (page 7).
Select the folder.

Maximum recording time
With the ICD-B10, you can record for up to 63 minutes in SP (standard
play) mode and 168 minutes in LP (long play) mode. If you record
messages in a mixture of SP and LP modes, the recordable time varies
from 63 to 168 minutes.
With the ICD-B15, you can record for up to 127 minutes in SP (standard
play) mode and 339 minutes in LP (long play) mode. If you record
messages in a mixture of SP and LP modes, the recordable time varies
from 127 to 339 minutes.
The unit is factory-set to SP mode. To  change the recording mode, see page 36.
You can check the remaining amount of recording time by selecting the
remaining recording time display mode. See page 34.
Remaining memory indication
During recording, the remaining memory indicator decreases one by one.
When the remaining time of recording reaches  5 minutes, the last one of
the indication flashes. When the remaining time of recording reaches 1
minute, the selected display mode (page 34) and “ REMAIN ”  will flash one
after the other in the display window.  When the memory is full, recording
automatically stops and  “ FULL ”  will flash in the display window with an
alarm sound. To  continue recording, first erase some of the messages (page
19).

Various Ways of Recording
Starting recording  automatically in response to the sound
— Advanced VOR function
When the VOR (voice operated recording) function is set to ON (page 36),
recording starts when the recorder detects sound and stops when no
sound is heard.
Note
VOR function is affected by the sound around you.  Set the microphone
sensitivity (SENS) to either HI (high) or LO (low) (see page 36). If recording is
not satisfactory after you have changed the microphone sensitivity, or for
important recording, set VOR to OFF.
Recording with an external microphone or from other
equipment
Connect a plug-in-power type microphone or other equipment to the MIC
(PLUG IN POWER) jack.
When you connect an external microphone,  the built-in microphone is
automatically cut off. When a plug-in-power type microphone is
connected, power is automatically supplied to the microphone from the IC
recorder.
Adding a recording
To  add a recording to a previously recorded message or to add an
overwrite recording during playback, see pages 21 and 22.
