COMPONENTS  IDENTIFIED  BY  MARK  0  OR  DOTTED  LINE
WITH  MARK  0  ON  THE  SCHEMATIC  DIAGRAMS  AND  IN
THE  PARTS  LIST  ARE  CRITICAL  TO  SAFE  OPERATION.
REPLACE  THESE  COMPONENTS  WITH  SONY  PARTS  WHOSE

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.

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.)

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.

• 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.

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.

Before making a long recording, be sure to insert new batteries and check the
battery indicator (page 7).

Select the folder.

e.g.

Message 1 Message 2
