ICD-B10/B15
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.
UNLEADED SOLDER
•
Boards requiring use of unleaded solder are printed with the leadfree 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.

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.

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.

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

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.
