E. REMOTE MONITOR AND CONTROL WITH ABS
This equipment is OPTIONAL and can be used to satisfy FCC remote control requirements.
The Remote Monitor is used to monitor the operational status of the transmitter and will allow the
operator to turn RF on or off and adjust power levels. The following items are monitored or controlled:
1. Transmitter on/off function
2. Power output level monitor and adjust
3. AC Line voltage status — With ABS you can be notied if there is a power failure at the side.
4. Various other custom options are available. Specify these at the time the transmitter is purchased
and they will be included if possible.
Remote monitoring requires a phone line connection. Information can be accessed via a PC Terminal or
via a “VOICE COMMAND LINE.” Either option is standard with this system.
The Auxiliary power unit requires a battery connection. A common car battery (12 VDC) can be used
with a charger as an ABS. This will run the Monitor and provide access to transmitter status for several
hours.
A manual for this equipment is provided by the Manufacturer and is included in the UTX3KW-A package
shipped with the transmitter. This manual is only included if this option was purchased for delivery
with the transmitter.
REFER TO INSTRUCTION MANUAL PROVIDED WITH THIS PACKAGE.

on the desired operating channel.
Detail operation of the Modulator with schematics and parts list is provided by the equipment manufac-
turer.
