CONTROL HEAD
The DVE Control Head selects mode of operation for both the and the Mobile Radio.
To Turn the ON or OFF
Press the button in the Volume knob located on the left side of the control unit. The display should
become active when the system turns ON. A test message appears briefly on the display. When the system
is turned ON, the Mobile Channel and DVE Mode will automatically return to the same settings that were in
effect when the power was last turned OFF. Press the button in the Volume knob second time to turn the DVE
OFF.
To Change the Speaker Volume
Turn the Volume knob until the desired volume level is reached.
To Change the Mode
Press the 'H/L' button once. The DVE mode is changed in the following sequence: MOBILE-SYSTEM-…
In the Mobile mode the alphanumeric display shows ‘ZONE CHANNEL’. In the System mode the display
changes to ‘RSYS CHANNEL’. (‘ZONE’ is the selected Mobile zone name while ‘CHANNEL’ is the selected
Mobile channel name.) When the SYSTEM mode is selected, the mobile radio scan is deactivated and the
mobile radio reverts to the selected mobile channel.
NOTE
The Mobile zone and channel cannot be changed while in SYSTEM mode.
Refer to the earlier description of repeat modes.
MOBILE XMIT Status Indicator
The 'MOBILE XMIT' red LED indicator is one of two status indicators that is provided on the Control
Head, located in the upper left corner. This indicator will light whenever the Mobile Transmitter is keyed. This
will occur in 'MOBILE' or 'SYSTEM' mode when the microphone Push-to-Talk is being pressed or when a
signal from the DVE is being retransmitted by the Mobile Radio (In 'SYSTEM' mode).
MOBILE BUSY Status Indicator
The 'MOBILE BUSY' orange LED indicator is one of two status indicators that are provided on the Control
Head, located in the upper left corner. This indicator will light whenever the Mobile Radio is receiving any
signal on the selected Mobile Channel. If CTCSS (Channel Guard) tone coding is used, the signal may not be
audible if the coding does not match.
Note that if the microphone is “off-hook”, the Mobile/ audio will be heard on the speaker even if CTCSS is
not present or is incorrect. This is the same as the Monitor function.
ALPHANUMERIC Status Indication
The ‘ZONE’ is not displayed in the SYSTEM repeat mode. Instead, this portion of the alphanumeric
display shows the status of the DVE in these two modes together with 'MOBILE XMIT' and 'MOBILE BUSY'
status indicators.
The following tables summarize indicators for different DVE states:
