3. OPERATION
CONTROL HEAD
The Repeater Control Head selects mode of operation for both the Repeater and the Mobile Radio.
To Turn the Repeater 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 Repeater 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 Repeater OFF.
To Change the Speaker Volume
Turn the Volume knob until the desired volume level is reached.
To Change the Repeater Mode
Press the 'H/L' button once. The Repeater mode is changed in the following sequence: MOBILE-SYSTEM-
LOCAL-… In the Mobile mode the alphanumeric display shows ‘ZONE CHANNEL’. In the System mode both the
Repeater and the Mobile Radio may transmit at the same time. In the Local mode the display shows ‘RLOC
CHANNEL’. (‘ZONE’ is the selected Mobile zone name while ‘CHANNEL’ is the selected Mobile channel name.)
When the LOCAL or SYSTEM repeat modes are 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 LOCAL and SYSTEM
repeat modes.
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
Vehicular Repeater 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/Repeater 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 LOCAL and SYSTEM repeat modes. Instead, this portion of the
alphanumeric display shows the status of the Repeater in these two modes together with 'MOBILE XMIT' and
'MOBILE BUSY' status indicators.
The following tables summarize indicators for different Repeater states:
