Buttons on the front

➀ MO/Fr/Ch
This button has many functions:
- By directly pressing this button, the low noise barrier can be bridged as long as
though the button MO is then released.
- If the button is pressed for longer than one second, statistical information will be
received one after the other for the different pilots as well as the search
jump-function.
After work the indicator receives rc off and tc off for switched off CTCSS
operations as well as SCSP off, because no channel is marked to jump.
For a switched on operation and activated sound squelch, rc and tc will be
indicated as well as the switched on CTCSS sound. If a channel is marked
to jump, then indicator on01 will follow from SCSP (for channel one in this case).
Afterwards the frequency can be read from the display.
- For the second function, the frequency and channel indicator can be changed on
the large display. Hold the FUNC button (indicator F) and simultaneously press
the MO/Fr/Ch button.

and transmission or general sounds can be indicated and then altered.
