INFORMATION

This document contains important safety and
operating instructions. Read these instructions
carefully and save them for future reference.

3. To reduce risk of damage to the electric plug

and cord, pull by the plug rather than the cord

when disconnecting the charger.

4. An extension cord should not be used unless

absolutely necessary. Use of an improper

extension cord could result in risk of fire and

electric shock. If an extension cord must be

used, make sure that the cord size is 18AWG

should be nearby and easily accessible.

• Maximum ambient temperature around the power

supply equipment must not exceed 40°C (104°F).

• Make sure that the cord is located where it will

not be stepped on, tripped over, or subjected to

water, damage, or stress.

Notes:

• To listen to all activity on a current channel, short

press the SB1 to set the CTCSS/DPL code to 0.

This feature is called ‘CTCSS/DPL Defeat

GETTING STARTED

To establish a proper two-way communication,
the channel, frequency, and interference
eliminator codes must be the same on both
radios. This depends on the stored profile that
has been preprogrammed on the radio:

1. Channel: Current channel that the radio is

using, depending on radio model.

4. Scramble Code: Codes that make the

transmissions sound garbled to anyone

listening who is not set to that specific code.

For details on how to set up frequencies and
CTCSS/DPL codes in the channels, refer to

FEATURES

To easily program all the features in your radio,
it is recommended to use the CPS
Programming Cable and CPS software.

The Interference Eliminator Code (CTCSS/
DPL) helps minimize interference by providing
you with a choice of code combinations that
filter out static, noise, and unwanted
messages.

Note: Before programming the features, make

sure your radio is set to the channel you
wish to program. You can do so before
entering Programming Mode or at any time
during the Programming Mode by turning
the Channel Selector Knob to the desired
channel

Each time your radio signals and beeps the
current setting you can change this setting by
either increasing it by short pressing SB1 or
decreasing it by short pressing SB2 . The
radio will then signal the new setting it has
been programmed.

• If you ‘roll-over’ to the beginning at Idle

Programming Mode you will hear a ‘chirp’ and the

LED Indicator will start blinking green again. All

values that were changed will be automatically

saved.

OTHER PROGRAMMING FEATURES

Scan

Scan allows you to monitor other channels to
detect conversations. When the radio detects a
transmission, it will stop scanning and will stop
on the active channel. This will allow you to
listen and talk to people on that channel without
having to change the channel knob. If there is

Notes:

• The features described in previous pages are just

some of the features CPS has. CPS offers more

capabilities. For more information refer to the

HELP file in the CPS.

• Some of the features available with the CPS

software may vary depending on the radio model.

CLONING RADIOS

You can clone RDX Series™ radio profiles from
one Source radio to a Target radio by using any
one of these 3 methods:

• a Multi Unit Charger (optional accessory),

• Two Single Unit Chargers (SUC) and a Radio-to-

Radio cloning cable (optional accessory),

or copied from) and

• a Target radio (the radio which profile will be

cloned from the source radio.)

The Source radio has to be in Pocket 1, 3 or 5
while the Target radio has to be in Pocket 2, 4
or 6, matching in the MUCs pockets by pairs as
follows:

• Wait for 3 seconds before releasing the

buttons until a distinctive audible tone is

heard.

3. Place the Source radio in the source pocket that

pairs with the target pocket you chose in step 1.

Press and release SB1.

4. After cloning is completed, the Source radio will

sound either a ‘pass’ tone (cloning was

2. Unplug any cables (power supply or USB

cables) from the SUCs.

the second SUC.

Note: During the cloning process no power is

being applied to the SUC. The batteries will
not be charged. A data communication is

7. After cloning is completed, the Source radio will

sound either a ‘pass’ tone (cloning was

successful) or a ‘fail’ tone (cloning process has

failed). The ‘pass’ tone sounds like a good key

‘chirp’ whereas the ‘fail’ tone sounds similar to a

‘bonk’ tone. If the Source radio is a display

model, it will either show ‘Pass’ or ‘Fail’ on the

display (a tone will be heard within 5 seconds).

3. Ensure that the battery is engaged properly on

to the radio.

4. Ensure that there is no debris in the charging

tray or on the radio contacts.

5. Ensure that the Source radio is in cloning mode.

6. Ensure that the Target radio is turned ON.

7. Ensure that radios are both from the same type

Cloning using the CPS (Computer
Programming Software)

When cloning using this method, you will need
to have the CPS software, a Drop-in Tray
Charger and the CPS Programming Cable.

To order the CPS Programming Cable, please
