Intercom Operation with External PTT Switch or ACU PPT Switch
•
Intercom operation with external PTT switch is for intercommunication in the connected
IC circuits.
•
It is possible to connect an external PTT switch or 2-state switch to each ACU to start a
"Hot Mike" mode.
Intercom Operation with External PTT Switch
TX-selector
•
Turn the TX-selector to a position IC.
•
Push and hold the external PTT switch or the ACU panel PTT switch.
o
Intercom operation is on.
•
The transmission mode always has a higher priority than the
intercommunication mode.
If a user starts the transmission mode for any transceiver, the ACU stops
its VOX or HOT MIKE mode and changes to transmission mode. Other
devices in the circuits are not affected and their operators can continue
intercommunication.
3.9 Winchman Operation
The winchman function includes VOX-level and volume-level adjustments without access to a control
device.
•
The winchman functionality can be given to any ACU610X or headset (without installed
ACU610X) by the configuration setup.
•
With two external push buttons the VOX-level and volume-level can be remotely controlled
by the winchman operator.
o
Push one of the two external push buttons and the winchman function will be started.
o
This enables the winchman to increase the VOX-level and the volume-level for his
headset.
•
• VOX-level adjustment:
o
Push the VOX-
level button for a short time (0.3...≤
3 s), the VOX-level is increased
until the maximum value is reached.
o
Push the button ≥
3 s, the VOX-level is reset to the value selected on the related ACU
panel.
o
The VOX-level is reset too, when the winchman function is set to off and the volume
control or VOX control on the ACU is changed
•
• Volume level adjustment:
o
Push the volume level button for a short time (0.3...≤
3 s), the volume level is
increased until the maximum value is reached.
o
Push the button ≥
3 s, the volume level is reset to the value selected on the related
ACU panel.
o
The volume level is reset too, when the main volume control or VOX control on the
related ACU is changed.
