INSTRUCTION MANUAL
This device complies with Part 15 of the FCC rules. Operation is sub-
ject 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 operation.

![](/img.php?id=15465&img=bg2.png)
RWARNING! NEVER hold the transceiver so that the
antenna is very close to, or touching exposed parts 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 op-
eration. 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 power 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 pro-
tection 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.

BATTERY PACKS AND ACCESSORIES
2
■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 dry 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
DOperating period
Depending on the attached battery pack, the operating period
of the transceiver varies. Refer to p. 28 for battery pack spec-
ifications.
DBattery 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

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 ac-
cording to band. In other words, a given memory channel can
be programmed with either a VHF frequency or a UHF fre-
quency. 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)
