INSTRUCTION MANUAL
This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired oper ation.
DUAL BAND FM TRANSCEIVER
iT7H
RW ARNING! NEVER hold the transceiver so that the
antenna is very close to, or touching exposed par ts of the
body, especially the face or eyes, while transmitting. The
transceiver will perform best if the microphone is 5 to 10 cm
(2 to 4 in) away from the lips and the transceiver is vertical.
RWARNING! NEVER operate the transceiver with a
headset or other audio accessories at high volume levels.
Hearing experts advise against continuous high volume operation. If you experience a ringing in your ears, reduce the
volume level or discontinue use.
NEVER connect the transceiver to an AC outlet or to a
power source of more than 16 V DC. Such a connection will
damage the transceiver.
NEVER
connect the transceiver to a pow er source that is DC
fused at more than 5 A. Accidental reverse connection will be
protected by this fuse, higher fuse values will not give any protection against such accidents and the transceiver will be ruined.
NEVER attempt to charge alkaline or dry cell batteries. Be-
ware that external DC power connections will charge batteries
inside the battery case. This will damage not only the battery
case but also the transceiver.
i
IMPORTANT
READ ALL INSTRUCTIONS carefully and completely before
using the transceiver.

BATTERY PACKS AND ACCESSORIES

■ Battery pack charging
The supplied* BP-180
BATTERY PACK
includes rechargeable
Ni-Cd batteries and can be charged approx. 300 times.
Charge the battery pack before first operating the transceiver
or when the battery pack becomes exhausted.
*Optional for versions which come with the BP-170
BATTERY CASE
.
If you want to be able to charge the battery pack more than
300 times, the following points should be observed:
1. Avoid overcharging. The charging period should be less
than 48 hours.
2.Use the battery until it becomes almost completely ex-
hausted under normal conditions. We recommend battery
charging just after transmitting becomes impossible.
■ Charging precautions
NEVER attempt to charge dr y cell batteries. This will cause
internal liquid leakage and damage the battery case and
transceiver.
NEVER connect two or more chargers at the same time.
Charging may not occur under temperatures of 10°C (50°F)
or over temperatures of 40°C (104°F).
■ About the battery pack
D Operating period
Depending on the attached battery pack, the operating period
of the transceiver varies. Ref er to p. 28 for battery pack specifications.
D Battery pack life
If your battery pack seems to have no capacity even after
being fully charged, completely discharge it by leaving the
power ON overnight. Then, fully charge the battery pack
again.
If the battery pack still does not retain a charge (or very little),
a new battery pack must be purchased.
Recycling information (U.S.A. only)
The product that you purchased contains a
rechargeable battery. The battery is recyclable. At
the end of its useful life, under various state and
local laws, it may be illegal to dispose of this battery into the
municipal waste stream. Call 1-800-8-BATTERY for battery
recycling options in your area or contact your dealer.

■ Repeater operation
D General
When using a repeater, the transmit frequency is shifted from
the receive frequency by the offset frequency. It is convenient
to program repeater information into memory channels
(p. 15).
➀ Set the operating band and receive frequency (repeater
output frequency).
➁ Push [(TONE)DUP]for 1 sec. once to select –DUP or twice
to select DUP.
•“–DUP” or “DUP” appears to indicate the transmit frequency for
minus shift or plus shift, respectively.
• When the auto repeater function is in use (U.S.A. version only)
this selection and step ➂ are not necessary (p. 24).
➂ Push [TONE] to activate the subaudible tone encoder, ac-
cording to repeater requirements.
•“T” appears.
• Refer to the table of tone frequencies on the following page.
➃ Push and hold [PTT] to transmit.
• The displayed frequency automatically changes to the transmit
frequency (repeater input frequency).
• If “OFF” appears, check the offset frequency (p. 14).
➄ Release [PTT] to receive.
➅ Push and hold [MONI] to check whether the other station’s
transmit signal can be directly received or not.
D Tone information
Some repeaters require a tone to be accessed. In this case,
precede step ➃ at left with the required tone.
DTMF TONES (U.S.A. and Asia versions only)
While pushing [PTT], push the desired digit key(s) to transmit
DTMF tones
• The transceiver has 9 DTMF memory channels. See p. 17 for details.
1750 Hz TONE (Europe and Italy versions only)
While pushing [PTT], push and hold [TONE] for 1 to 2 sec. to
transmit a 1750 Hz tone signal.
✔ CONVENIENT
Tone scan function: When you don’t know the subaudible
tone used for a repeater, the tone scan is convenient for detecting the tone frequency.
Push and hold [T SCAN?] to activate. See p. 22 for more information.

Memory/call channels
The transceiver has 70 memory channels (60 regular, 4 pairs
of scan edge channels for mixed bands and 1 call channel for
each band). Note that memory channels are not grouped according to band. In other words, a given memory channel can
be programmed with either a VHF frequency or a UHF frequency. This is not the case with call channels. Call channels
are band specific.
The following can be programmed into memory/call channels:
• Operating frequency
• Duplex direction with an offset frequency (pgs. 13, 14)
• Subaudible tone encoder or tone squelch ON/OFF with a
tone (CTCSS) frequency (pgs. 21, 22)
• Skip information (p. 20)

calls from group members using the same tone.
➀ Set the operating frequency.
➁ Set the desired subaudible tone in set mode.
• See right for programming.
➂ Push [TONE] one or more times until “TSQL” appears.
➃ When the received signal includes a matching tone,
squelch opens and the signal can be heard.

does not open, however, the S-indicator shows signal strength.
• To open the squelch manually, push and hold [MONI].

NOTE: The transceiver has 50 tone frequencies and consequently their spacing is narrow compared with units having 38 tones. Therefore, some tone frequencies may
receive interference from adjacent tone frequencies.
D Pocket beep operation
This function uses subaudible tones for calling and can be
used as a “common pager” to inform you that someone has
called while you were away from the transceiver.
➀ Set the operating frequency.
➁ Set the desired subaudible tone (same as that used for
tone squelch operation, “CT”) in set mode.
• See p. 21 for programming.
➂ Push [TONE]two times until “TSQLS” appears.
➃ When a signal with a matched tone is received, the trans-
ceiver emits beep tones for 30 sec. and flashes “S.”
➄ Push [PTT] to answer or push [VFO] to stop the beeps and
flashing.
• Tone squelch is automatically selected.
D Calling a waiting station using pocket beep
A subaudible tone matched with the station’s tone frequency
is necessary. Use the tone squelch on p. 21 or a subaudible
tone encoder.

D Tone scan
The transceiver can detect the subaudible tone frequency in a
received signal. By monitoring a signal, such as that being
transmitted on a repeater input frequency, you can determine
the tone frequency required to access the repeater.
➀ Set the desired frequency or memory channel to be
checked for a tone frequency.
➁ Push [T SCAN] for 1 sec. to start the tone scan.
• To change the scanning direction, rotate [DIAL].
➂ When the tone frequency is decoded, the set mode con-
tents are programmed with the tone frequency.
• The decoded tone frequency is used for the tone encoder or tone
encoder/decoder, depending on the the tone squelch ON/OFF
setting.
•“CT” or “rT” appears during tone scan when the tone squelch is in
use or not, respectively.
➃ Push [VFO] to stop the scan.
