TROUBLESHOOTING
If you have trouble operating the handheld, review the
radio controls and operation sections. If you think the
radio is malfunctioning, check the following table.

Recharge or replace the battery. (See note 1.)
Operating features do not work exactly as expected.
•
The radio has been factory or dealer
programmed for customized operation.
Reception is poor.
•
Move to a different location. (Note 2.)
•
Confirm that the proper antenna is connected to
the radio. (See p. 11, "Antenna.")
You cannot hear calls from other radios.

(Note 4.)
•
Recharge the battery. (Note 1.)
TONE CODED SQUELCH
You cannot screen out calls from users outside of
your tone group.
•
Make sure the channel is programmed with tone
squelch.
•
Activate Tone (coded) squelch. (Note 7.)
You cannot hear Tone coded messages while in
Tone (coded) squelch.
•
Confirm that the channel is programmed to
detect the same code as the calling radio(s)
transmits. (Note 7.)
Others in your tone group cannot hear your tone
coded messages.
•
Verify that you transmit the same code as the
radio(s) you call are programmed to detect.
(Note 7.)
ERROR TONES
An error tone sounds when the radio is first
turned on.
•
Replace the battery. (Note 1.)

Refer to “Error Tones”
BATTERY
The battery loses its charge sooner than
expected.

Review the battery charging instructions.
•
Conserve the battery. (Note 5.)
•
If the radio is used in extreme cold, warm the
radio under your coat. (Note 6.)
Notes
1. Try a battery pack from a working radio. If the radio in
question works with that pack, the original battery is
suspect. Charge the suspect battery as recommended
in this manual. Then, if the charged original battery
cannot power the handheld, try charging again with
another charger. If the battery still doesn’t hold a
charge, the pack should probably be replaced.
However, if the battery appears to be good after you try
the second charger, the first charger might be faulty. If
you think that an accessory is not operating properly,
contact your dealer or RITRON. (Radio accessories
come with a 90-day limited warranty.)
2. Reception can often be improved by moving a short
distance. This effect is more noticeable inside of
buildings. The range of these portables equipped with
a standard battery pack is about two miles (line-of-
sight).
3. If your radio does not detect calls from other radios on
the channel, turn off tone squelch. (Press both Volume
buttons at the same time - a double beep means that
tone squelch is off.)
4. If you want to hear a call, you must select a channel
that is programmed to receive the caller’s transmit
frequency. If you want to call another unit, you must
select a channel that is programmed to transmit the
other radio’s receive frequency. However, if you use a
repeater, your channel must be programmed to work
with the repeater’s transmit and receive frequencies.
(A radio channel can hold two separate operating
frequencies, one for Receive, the other for Transmit.)
5. Maximum power drain occurs while the radio transmits,
so don’t hold down the Push-To-Talk button more than
necessary. Battery power is used while the handheld is
left on to receive calls. If practical, switch off the unit.
6. In extreme cold, a battery’s charge capacity is greatly
reduced. If you use the radio in very cold weather,
periodically warm the portable underneath your coat if
possible. An optional remote speaker/microphone
would allow you to keep the radio under your coat while
transmitting and receiving.
7. In order for radios to communicate using Quiet Call,
they must be programmed with the same tone code.
Each code is unique, and your radio will respond only
to the code programmed. Press and hold both volume
buttons at the same time. A single beep means that
tone squelch is on. A double beep means that tone
squelch is off.
