FCC REGULATIONS
LICENSING 
The FCC requires the owners of the radios to obtain a station license before using them.
The station licensee is responsible for ensuring that transmitter power, frequency and deviation
are within the limits specified by the station license. The station licensee is also responsible for
proper operation and maintenance of the radio equipment, including checking the transmitter
frequency and deviation periodically by use of appropriate methods.
To get a FCC license for VHF or HF frequencies, submit FCC application Form 600 as
indicated in the block at right. Your Ritron dealer can help you with this process.
SAFETY STANDARDS 
The FCC (with its action in General Docket 79-144, March 13, 1985) has adopted a safety
standard for human exposure to radio frequency electromagnetic energy emitted by FCC-
regulated equipment. Ritron observes these guidelines and recommends that you do also:
 DO NOT hold the radio so that the antenna is very close to or touching exposed parts of
the body, especially the face or eyes, while transmitting. Keep the radio vertical, two-to-
three inches away while talking into the front panel.
 DO NOT press the Push-To-Talk except when you intend to transmit.
 DO NOT operate radio equipment near electrical blasting caps or in an explosive
atmosphere.
 DO NOT allow children to play with any radio equipment that contains a transmitting
device.
 Repair of Ritron products should be performed only by Ritron authorized personnel.
SERVICE
Federal law prohibits you from making any internal adjustments to the transmitter, and/ or from
changing transmit frequencies unless you are specifically designated by the licensee.
If your radio equipment fails to operate properly, or you wish to have the radio programmed,
contact your authorized dealer or Ritron.

BATTERY MAINTENANCE & CONDITIONING
Achieve maximum battery life by fully discharging the
battery periodically to condition it.
Condition battery packs by the following procedure as
either a preventive measure, or if you suspect reduced
capacity:
TO CONDITION THE BATTERY PACK:
1.  Use your radio for a normal work day without
charging it.
2. If your radio is used only in the Trunked Mode
you need only leave the radio turned On.
If your radio is used in Conventional Mode, with
the radio turned ON, hold the monitor button for
3 seconds to place the radio (on a Conventional
channel) in open squelch mode. Release the
monitor button when you hear the radio beep
rapidly; you will then hear a "rushing" noise. Turn
the Volume Control knob fully clockwise to
maximize this noise.
3.  Put the radio away in a secure place -- possibly a
desk drawer -- where nothing can press against
the buttons or controls to accidentally turn it Off or
cause it to transmit. Allow the radio to run until it
shuts off when the battery is completely discharged.
A typical battery pack may require about 8 hours to
completely discharge.
4.  When the radio has shut off, charge it overnight for
12 to 16 hours. The battery will be ready for use
with renewed capacity.
NOTE: A new battery must be fully discharged, then
recharged several times before it will reach its
maximum charge capacity.
GENERAL
The RTX Plus eries radio is powered by a rechargeable battery pack.
CHARGING
Because the battery pack loses its charge during storage and shipment, fully charge it before first use. To ensure
maximum performance for the next day, charge the battery overnight after each day of use.
TO CHARGE THE BATTERY USING A RITRON CUBE CHARGER: Plug the charger cord into the charge jack
(marked "CHG") on top of the radio. Then plug the cube into an 110 VAC outlet. The GREEN lamp lights while
the battery is charging, and should go out only when the cube or cord is unplugged.
TO CHARGE THE BATTERY USING A RITRON DROP-IN CHARGER: Three charger contacts, visible through
the radio case bottom, permit charging the battery with an optional Ritron drop-in charger. The battery pack may
be either removed from the radio case for charging, or charged inside the radio case.
Each drop-in charger comes with a spacer to permit charging a "spare" battery while the radio is in use.
To use the drop-in charger, plug it into a 110 VAC outlet. et either the radio with the battery installed, or only
the battery with the battery spacer, into the charger. Each battery contact must rest on a charger contact pin.
BATTERY REMOVAL/ INSTALLATION
Unlock the door latch (see FIG-2, page 5). Press down on the door and slide it off the radio. Turn the portable over
and tap the battery compartment against the palm of your free hand until the pack drops into your hand.
To install the door align it with the battery compartment, the top edge of the door facing the antenna. Place the
door as described, then slide it up and into the slots shown in FIG-2, page 5. Be sure to lock the door latch.
PRECAUTIONS AND NOTES
NOTE: Use only RITRON-supplied chargers; other chargers may cause fire, explosion or other damage.
Battery pac life averages one year. Follow these guidelines to maximize service life:
 FULLY DI CHARGE the battery before recharging it.
 CONDITION battery packs once a month as directed in Battery Maintenance & Conditioning.
 CONDITION batteries that are run down.
 CHARGE batteries for 16 hours before storage, and for 16 hours once a month thereafter.
 DO NOT overcharge batteries. Unplug the cube charger after 16 hours to avoid overcharging.
 DO NOT "fast" charge a brand new battery pack, because this may damage the battery. Once the battery
has been charged using the "trickle" rate, the fast rate may be used thereafter.
 DO NOT "fast" charge a fully charged battery. This can shorten battery life.
 DO NOT charge batteries in temperatures colder than about 45°F. Charging batteries in temperatures
above 95°F. does not harm them, but can reduce charge capacity.
 DO NOT charge or replace a battery in an explosive atmosphere. Contact sparking can ignite an explosion.
 DO NOT dispose of a battery in a fire. An explosion might result.

(marked "CHG") on top of the radio. Then plug the cube into an 110 VAC outlet. The GREEN lamp lights while
the battery is charging, and should go out only when the cube or cord is unplugged.
TO CH RGE THE B TTERY USING RITRON DROP-IN CH RGER: Three charger contacts, visible through
the radio case bottom, permit charging the battery with an optional Ritron drop-in charger. The battery pack may
be either removed from the radio case for charging, or charged inside the radio case.
Each drop-in charger comes with a spacer to permit charging a "spare" battery while the radio is in use.
To use the drop-in charger, plug it into a 110 VAC outlet. Set either the radio with the battery installed, or only
the battery with the battery spacer, into the charger. Each battery contact must rest on a charger contact pin.
BATTERY REMOVAL/ INSTALLATION
Unlock the door latch (see FIG-2, page 5). Press down on the door and slide it off the radio. Turn the portable over
and tap the battery compartment against the palm of your free hand until the pack drops into your hand.
To install the door, align it with the battery compartment, the top edge of the door facing the antenna. Place the
door as described, then slide it up and into the slots shown in FIG-2, page 5. Be sure to lock the door latch.
PRECAUTIONS AND NOTES
NOTE: Use only RITRON-supplied chargers; other chargers may cause fire, explosion or other damage.
Battery pac life averages one year. Follow these guidelines to maximize service life:
 FULLY DISCHARGE the battery before recharging it.
 C NDITI N battery packs once a month as directed in Battery Maintenance & Conditioning.
 C NDITI N batteries that are run down.
 CHARGE batteries for 16 hours before storage, and for 16 hours once a month thereafter.
 D N T overcharge batteries. Unplug the cube charger after 16 hours to avoid overcharging.
 D N T "fast" charge a brand new battery pack, because this may damage the battery. nce the battery
has been charged using the "trickle" rate, the fast rate may be used thereafter.
 D N T "fast" charge a fully charged battery. This can shorten battery life.
 D N T charge batteries in temperatures colder than about 45°F. Charging batteries in temperatures
above 95°F. does not harm them, but can reduce charge capacity.
 D N T charge or replace a battery in an explosive atmosphere. Contact sparking can ignite an explosion.
 D N T dispose of a battery in a fire. An explosion might result.

TROUBLESHOOTING 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 an RTX lus 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 any accessory is not operating properly, contact
your dealer or RITRON.
2. Reception can often be improved by moving the radio a short
distance. This effect is more noticeable inside buildings. The range of
RTX lus portables equipped with a standard battery pack is about
five miles, line-of-sight.
3. If your radio does not detect calls from other radios on the same
channel, turn Off Quiet Call squelch. (For the status of QC squelch,
press the Monitor switcha single beep indicates QC squelch is On;
a double beep indicates QC squelch is Off.)
4. CONVENTIONAL OPERATION: To hear a call, select a channel
programmed to receive your caller's transmit frequency. To call
another unit, select a channel programmed to transmit the other
radio's receive frequency.
TRUNKED/ REPEATER OPERATION: To operate in a repeater
system, your channel(s) must be programmed to work with the
repeater's transmit and receive frequencies. (NOTE: A radio channel
can hold two separate operating frequencies one to receive; one to
transmit.)
5. Because maximum battery power drain occurs when the radio is
transmitting, do not hold down the ush-To-Talk button longer than
necessary when transmitting each call. Some power is used if the
radio is left On to receive calls. When practical, switch Off the unit.
6. In extreme cold, battery charge capacity is greatly reduced. If you use
the RTX lus portable in very cold conditions, periodically warm the
radio under your coat if possible. Use of an optional remote speaker/
microphone will allow you to keep the radio under your coat while
transmitting and receiving.
7. For radios to communicate using Quiet Call, each unit must be
programmed with the same Quiet Call code. Every code is unique,
and your radio will respond only to the code programmed for the
channel.
(For the status of QC squelch, press the Monitor switcha single
beep indicates QC squelch is On; a double beep indicates QC
squelch is Off.)
