VHF System Description

To the VHF system can be connected up to 7 control units. Each
control unit has a unique location (1-7). If a control unit wants to
control the transceiver, it has to be master of the system. The
following describes the display read-outs shown in connection  with
different system priorities of the control units:

The control unit assigned location number 1 has the highest priority
in the VHF system and is able to become master of the system at
any time

 

needed.

When more control units are connected to the VHF system, the main
control unit has to be assigned location number 1.

When the system is free:

If a control unit is in VHF mode, it shows the VHF display.

If a control unit in DSC mode or the function menu is active, the
display shows the menu item.

When a control unit is master of the system,

the other control units, if in VHF mode, show the following display to
indicate that the transceiver is in use by another control unit:

If the other control units are in DSC mode or the function menu is
active, the display will show the menu item as usual.

Getting the MASTER priority in the system:

To operate the transmitter, the control unit has to be master of the
system. To become master of the system, simply hook off the
handset.
When the control unit becomes master of the system, the display will
not change.

If the control unit does not become master of the system and it is
operated in VHF mode, the display will show the message:

If the system is occupied by another control unit, hang up and wait
for the system to become free.
