· A transmitting output of 500 mW, with 14

channels. Can communicate with other FRS two-

way radios with the same frequency channels.

· Handy size, easy to operate.

· Group Talk feature -- Allows you to communi-

cate only with units on the same channel with

the same group number, including other models

with the same feature.

· Search feature -- Automatically searches for

unused channels and calls up members of your

group.

Precautions

Placement

· Do not leave the unit near heat sources, such as

radiators or air ducts, or in a place subject to

direct sunlight, excessive dust, humidity, rain,

mechanical vibration or shock.

Do not leave the unit in a car parked in the sun,

especially in the summer.

· In vehicles or in buildings, transmission and

reception may be difficult or noisy. Try using the

unit near a window.

· When the unit is not to be used for a long time,

remove the batteries to avoid possible damage

caused by undue battery discharge, leakage or

corrosion.

· The nameplate indicating operating voltage,

etc. is located at the rear exterior.

· Should any solid object or liquid fall into the

unit, remove the batteries and have the unit

checked by qualified personnel before operating

it any further.

· Since a strong magnet is used for the speaker,

metallic objects such as pins, etc. may cling to the

Switching transmission

modes

This unit has three transmission modes. Select

according to situation.

Basic mode

When there is no intereference.

Group Talk mode When there is interference by

other groups using the same

channel.

Search mode

When you have trouble finding

an unused channel.

Each press of MODE will change the transmission

mode as follows:

Basic mode

1 Decide on a channel number (1 to 14)

with the member(s) of your group.

2 Press MODE repeatedly so that neither

The unit goes into the Basic mode.

3 Switch CH/GROUP to CH and press

+/ to select the channel.

4 Transmit.

Example: When using channel number 5

You can talk with anyone with a Sony or other

FRS two-way radio that is within the effective

range and is set to the same channel .

In the Basic mode, you can hear transmission

by any other two-way radio on the same

channel that is within the effective range.

Group Talk mode

In the Group Talk mode, the unit communicates

only with other units that are on the same channel

and the same group number.

1 Decide on a channel number (1 to 14) and

a group number (1 to 38) with the

same channel, you can block out transmission

of other groups by switching to the Group Talk

mode. (Transmission of other groups may still

interfere, however, if the other groups use the

same channel and group number).

Search mode

In the Search mode, the unit will search for an

unused channel and call up the members of your

group (i.e., other users with their ICB-U655s set to

the Search mode and to the same group number).

After first setting the group number, you need to

initiate Search by sending the call signal.

Setting the group number

standby status, and the segments of the channel

number display will light up in a rotating

motion.

Initiating Search

1 Hold down TALK.

The unit searches for an unused channel.

When the unit finds an unused channel, it rings

and sends off a call signal to other members of

your group.

2 Release TALK when your unit rings.

The ring will continue for about 10 seconds.

To stop the call signal manually, press TALK

again. The ringing will stop.

When you receive the call signal

Your unit switches automatically to the same

channel with the unit that sent the call signal, and

will ring. The ring will continue for about 10

seconds.

The Search system does not work with models

other than the ICB-U655.

On channels

Two-way radios can only locate other units that

are on the same channel. Please note that the

frequency range may differ with the model of the

two-way radio.

On effective range

The effective range of the unit depends upon

operating conditions, but should cover about 2

miles in suburban areas, with full battery power.

Clarity of transmission may worsen at locations

with heavy car or railroad traffic.

On transmission modes, channel and

group number settings

When the unit is turned on by pressing POWER,

the transmission mode, channel and group number

settings for the previous transmission will be

displayed.

If, however, the batteries have been replaced or the

car battery cord have been plugged or unplugged

from the DC IN 4.5V jack since the last transmis-

sion, the channel and group number may change

to 1.
