QUIET CALL TONE CODES (Interference Eliminator Codes)
Tone codes filter out static, noise and reduce unwanted "chatter" on radio
channels. When you operate on a frequency with a tone code, you screen out
most interference. This allows you to communicate with less interference and
to hear only those users in your radio group.
IMPORTANT: All radios in the talk group must operate on the same frequency
and tone code.

BATTERY MAINTENANCE & CONDITIONING
Du to th xt nd d run tim of th JMX S ri s radios, som us rs
may n v r fully discharg th NiCad batt ry pack during normal us .
Achi v maximum batt ry lif by fully discharging th batt ry
p riodically to condition it.
Aft r xposing th batt ry pack to many cycl s of not fully
discharging it b for r charging, th radio may xhibit r duc d
batt ry capacity. This r duc d capacity is vid nt wh n, aft r
s v ral hours of us , batt ry voltag drops whil th radio is
transmitting, causing th radio to mit a d ad batt ry warning ton
and shut its lf off.
Condition batt ry packs by th following proc dur as ith r a
pr v ntiv m asur , or if you susp ct r duc d capacity:
TO CONDITION THE BATTERY PACK:
1. Us your radio throughout a normal work day without charging.
2.  Pr ss and hold th On/ Volum Up and Volum Down/ Off
buttons simultan ously for 8 s conds to plac th radio in
"op n squ lch" mod .
 R l as both buttons wh n you h ar th radio b p rapidly; it
will th n mit a loud "rushing" nois . Pr ss On/ Volum Up to
maximiz this nois .
3.  Put th radio away in a s cur plac (possibly a d sk draw r),
wh r nothing can pr ss against th buttons to accid ntally
turn it off or caus it to transmit. Allow th radio to run until it
shuts off wh n th batt ry is compl t ly discharg d. A typical
batt ry pack may r quir about 8 hours to compl t ly
discharg .
4.  Wh n th radio has shut off, charg it ov rnight for 12-14
hours. Th batt ry will b r ady for us with r n w d
capacity.
NOTE: A new battery must b charg d and discharg d s v ral
tim s b for it can r ach its maximum charg capacity.
CAUTION: Use only RITRON-supplied chargers; using other chargers may cause fire
or explosion, or otherwise damage the radio.
GENERAL
Th JMX S ri s radio is pow r d by a r charg abl batt ry pack.
CHARGING
B caus th batt ry pack los s its charg during storag and shipm nt, fully charg it b for first
us . To nsur p ak radio p rformanc for th n xt day, charg th batt ry ov rnight aft r ach
day of us . It compl t ly charg s in about t n hours.
To charge the battery with a RITRON cube charger
Plug th charg r cord into th charg jack (mark d "CHG") on top of th radio. Th n plug th
cub into an 110 VAC outl t. Th gr n lamp lights whil th batt ry is charging, and should go
out only wh n th cub or cord is unplugg d.
To charge the battery with a RITRON drop-in charger
Two charg r contacts, visibl through th radio cas bottom, p rmit charging th batt ry with an
optional Ritron drop-in charg r. Th batt ry pack may b ith r r mov d from th radio cas for
charging, or charg d insid th radio cas .
Each drop-in charg r com s with a spac r to p rmit charging a "spar " batt ry whil th radio is
b ing us d.
To us th drop-in charg r, plug it into a 110 VAC outl t. S t ith r th radio with th batt ry
install d, or only th batt ry with th batt ry spac r, into th charg r. R f r to th illustration in
Optional Acc ssori s, opposit . Each batt ry contact must r st on a charg r contact pin.
NOTE:
Battery pack life averages one year. Follow these guidelines to maximize service life:
 CONDITION batt ry packs onc a month as dir ct d in Batt ry Maint nanc & Conditioning, at
right.
 CONDITION batt ri s that ar run down.
 CHARGE batt ri s for 16 hours b for storag , and for 16 hours onc a month th r aft r.
 DO NOT ov rcharg batt ri s. Unplug th cub charg r aft r 16 hours to avoid ov rcharging.
 DO NOT charg batt ri s in t mp ratur s cold r than about 45°F. Charging batt ri s in
t mp ratur s abov 95°C. do s not harm th m, but can r duc charg capacity.

If you think the radio is malfunctioning, check the list below.
Problem Possible Solutions
GENERAL

Reception is poor. Move to a different location. See Note 2.)
Confirm the proper antenna is connected to the radio. See page 2, "Antenna.")
You cannot hear calls from other radios. Turn off Quiet Call coded) squelch. See Note 3.)
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 other radios. Make sure that your radio transmits on the receive frequency of the radio s) you
want to call. See Note 4.)
Recharge the battery.
BATTERY
Battery loses charge sooner than expected. Review battery charging instructions, page 9.
Conserve the battery. See Note 5.)
If the radio is used in extreme cold, warm the radio under your coat. See Note 6.)
Replace the battery; see FIG-5, page 8. See Note 1.)

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 itron
about an accessory that is not operating properly.
2.  eception 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.
