If you have trouble operating the handheld, review the Controls & Operation, pages 2 through 5.
If you think the radio is malfunctioning, check the list below.
Problem Possible Solutions
GENERAL
The radio does not work at all. • Make sure that the battery is installed correctly, as shown in FIG-7. page 11.
• Recharge or replace the battery. (See pages 11 & 12.)
Operating features do not work • The radio has been dealer programmed for customized operation.

Reception is poor. • Move to a different location. (See Note 2.)
• Confirm the proper antenna is connected to the radio. (See page 2, Antenna)

other radios. • Ensure radio receives on the same frequency as the caller transmits. (See Note 4.)
• Recharge the battery. (See Note 1.)
Your calls cannot be heard in • Make sure that your radio transmits on the receive frequency of the radio(s) you

• If the radio is used in extreme cold, warm the radio under your coat. (See Note 6.)
• Replace the battery; see FIG-7, page 11. (See Note 1.)

messages.
TROUBLESHOOTING
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. If this
original battery cannot power the radio, try charging it again with
another charger. If the battery still doesn't hold a charge, the pack
should probably be replaced.
• If the battery appears to be "good" after using the second charger,
the first charger may be faulty. Contact a dealer or Ritron about an
accessory that is not operating properly.
2. • Reception can often be improved if you relocate by a short
distance. This effect is more noticeable inside buildings.
• The range for SST radios is about two miles, line-of-sight.
3. If your radio does not detect calls from other radios on the channel,
turn off Quiet Call by pressing and holding both volume buttons at
the same time—a double beep indicates Quiet Call is off.
4. • Without use of a repeater: To hear a call, select a channel
programmed to receive the caller's transmit frequency. To call
another unit, select a channel programmed to transmit the other
radio's receive frequency.
• Using a repeater: A radio channel can hold two separate operating
frequencies, one for receive and one for transmit. Your channel
must work with the repeater's transmit and receive frequencies.
5. • Maximum power drain occurs when the radio transmits, so don't
hold down the PTT more than needed to transmit.
• Battery power is used while the handheld is left on to receive calls. If
practical, switch off the unit.
6. • Battery capacity is greatly reduced in extreme cold.
• To use the radio in very cold weather, periodically warm it under
your coat if possible.
• An optional remote speaker/ microphone allows keeping the radio
under your coat while transmitting and receiving.
7. • To "talk" with each other, radios must be programmed identically for
Quiet Call code, as well as frequency. Each code is unique; radios
respond only to the code programmed.
• Press and hold both volume buttons at the same time.
A single beep indicates Quiet Call squelch is on.
A double beep indicates Quiet Call squelch is off.
