 INSTRUCTION MANUAL

Duplex can be enabled or disabled on individual channels. When Duplex is enabled on 
the selected channel, 

 F 

 is displayed.

The Duplex mode is set through the Menu. Please refer to the Menu options further be-
low.

Simplex/Duplex Range Comparison

SCANNING

Channel scanning allows you to monitor all channels for incoming signals.

NOTE:

  While the radio is scanning, by pressing the 

MENU/EXIT

 key will stop the scan-

ning or pressing the 

UP/DOWN

 key will change the scan direction.

TO ADD OR REMOVE SCAN CHANNELS

NOTE:

 By default, all channels are in the scan memory.

1.  Press the UP or DOWN keys to select the desired channel. Channels with the icon 

SCN visible are already in the scan memory while those that do not display the icon 
are not presently stored in the scan memory.

2. When the desired channel is displayed, press 

MENU

, go to option “

SC.ADD

”, press 

MENU again and select 

ADD

 to add the selected channel to the scan memory or 

DEL

 

to remove it from the scan memory.

TO SCAN

Press and hold the F2 key for 2 seconds, then channel numbers will change as the radio 
scans through the channels. To change the scan direction while scanning, briefly press 

UP

 or 

DOWN

.

To stop scanning, briefly press 

EXIT

 then the radio will return to normal operation.

SCANNING FEATURES

 

y

If a signal is received, the scan is paused allowing you to transmit and receive on that 
channel. Once the channel has been inactive for 5 seconds the scan will automatically 
resume.

 

y

Pressing the 

PTT

 switch while the radio is scanning will stop the scanning and start 

to transmit on that channel. The scan will not resume.

 

y

If the scan is paused on a busy channel that you don’t wish to listen to, press the 

UP

 

or 

DOWN

 keys to ‘skip’ over the channel and continue scanning after 5 seconds.

TIP:

  The Scan mode will reduce the overall battery life because the Standby (battery sav-

er) feature is overridden. If the battery is running low you should avoid scanning to 
conserve power.

CTCSS AND DCS

CTCSS (Continuous Tone Coded Squelch System) and DCS (Digital Coded Squelch) are 
similar Squelch quieting systems that allow groups of users to share the same channel 
without disturbing each other. The CTCSS system uses 1 of 50 low frequency tones to 
open and close the Squelch on the radio. The DCS system is similar to CTCSS but uses 1 
of 104 digital codes to control the Squelch. When CTCSS or DCS is enabled on your ra-
dio, only signals that are using the same code as your radio will be heard in the speaker 
and the Squelch will remain closed to all other signals.

NOTE:

 CTCSS and DCS codes do not prevent others from hearing your transmission.

CTCSS/DCS tones are switched off by default. To use CTCSS/DCS you must first enable 
a suitable CTCSS/DCS code using the Menu (see Menu options for more details). Your 
choice of CTCSS or DCS will largely depend on which is currently being used by other 
radios in your group. If neither system is currently in use, you can make your own choice. 
There is no difference in performance between the two systems. Once a CTCSS or DCS 
code has been enabled, the display will show 

 CT 

 (for CTCSS) or 

 DCS 

 (for DCS).
