Your radio allows you to enable or disable Duplex
mode on individual repeater channels. In this way
any repeater channels that are not being used with
repeaters in your area can be used in Simplex mode
for normal direct radio-to-radio communications.
To enable or disable Duplex on a Repeater Channel
1. Select the required repeater channel (1 – 8,
41 – 48).
2. Press and hold the Channel control to enter the
menu. The display will show the current Squelch
level setting.
3. Rotate the Channel control until ‘DUPxx’ is
displayed (where xx = ON or OF), then press the
Channel control to select it.
NOTE:
If ‘DUP- -‘ is displayed, the selected
channel is not a repeater channel. Please exit the
menu and select a repeater channel.
4. Rotate the Channel control to the right
to enable Duplex on the selected channel.
‘DUPON’ will be displayed and
the icon
will appear.
5. Rotate the Channel control to the left to
disable Duplex on the selected channel.
‘DUPOF’ will be displayed and
the icon
will disappear.
When finished press and hold the Channel
control to exit the menu.
