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 damaged 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.

1

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.

	When	flashes, replace the batteries with new ones.
	When	flashes, the batteries are exhausted and the unit will stop
	operation.

	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.

Step 2: Setting the Clock

You need to set the clock to use the alarm or timer setting function. 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. In this case, proceed from step 2.

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.

e.g. Message 1 Message 2 Newly recorded message Blank space

Note

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

See page 36.

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.

the messages are played back rapidly,	and normal playback will start at
the point you release the button.
When “ END ” stops flashing and the OPR indicator goes off, the unit will
stop at the beginning of the last message.
If the last message is long and you wish to start playback at a later part of
the message, keep> pressed to play back the message to the end and
then press . while “ END ” is flashing to go back to the desired point .
(For messages other than the last one,	go to the beginning of the next
message and play backward to the desired point.)

Locating quickly the point you wish to start playback (Easy Search)

When EASY-S is set to ON (page 36), you can quickly locate the point you wish to start playback by pressing > or . repeatedly during playback or playback pause.

You can go back approx. 3 seconds by pressing. once, or advance approx 10 seconds by pressing> once. This function is useful when locating a desired point in a long recording.
