3) ROGER BEEP
When the function is active, the icon
The Roger Beep sounds when the PTT switch (11) on the microphone is re-
leased in order to let your correspondent speak. Historically as transceiver
is a "simplex" communication mode, it is not possible to speak and to listen
at the same time (as it is the case with a telephone). Once someone had
finished talking, he said "Roger" in order to prevent his correspondent that
it was his turn to talk. The word "Roger" has been replaced by a significant
beep. There comes "Roger beep" from.
1. Turn on the power while pressing the UP button (12) on the microphone.
The display shows " " and the current status on the function: OF or On.
2. Repeat the point 1 until the display shows the desired status.
3. Release the UP key on the microphone.
When the function is activated "BP" appears on the display.
Default ROGER BEEP is OF.
4) FREQUENCY BAND SELECTION
(Configuration: EU; PL; d; EC; U; In)
The frequency bands have to be chosen according to the country of use.
Don't use any other configuration. Some countries need a user's licence.
See table page 50.
1. Turn on the power while pressing the F key (7). The letter corresponding to
the current configuration is blinking.
2. In order to change the configuration, use the ROTARY knob (4) on the unit
or the UP/DN buttons (12) on the microphone.
3. When the configuration is selected, press the F key (7) during 1 second. The
letter corresponding to the configuration is continuously displayed and a
confirmation beep sounds.
4. At this point, confirm the selection by switching off the transceiver and then
switching it on again.
See the frequency bands table at pages 45 to 47 / configuration table
page 49.
5) RESET
Resets all user-defined settings and returns to default values.
1. Turn on the power while pressing the EMG key (6). "
2. Long press F knob (7) to reset. A long beep confirms that the re initialization
have been done.
3. If no key is pressed for 5 seconds or if the PTT switch (11) is pressed, the unit
exits RESET without change.
