Troubleshooting; Notes; Chart - Ritron Jobcom JMX-152 Owner's Manual

NOTES

1. • Try a battery pack from a working radio. If the radio in ques-
tion works with that pack, the original battery is suspect.
• Charge the suspect battery as recommended in this man-
ual. If this original battery cannot power the radio, try charg-
ing 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 JMX/ 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.
