4. The Battery Backup field specifies the output power of the
station when a low DC supply voltage is detected by the station.
This field is intended primarily for use in DC-powered
applications such as running off a car battery.
The Battery Backup setting should be 10 watts or less and
should typically be lower than the Normal setting. The station
will switch from the Normal to the Battery Backup power
setting when A+ on the backplane drops below approximately 12
volts for UHF R4 or approximately 11 volts for all other ranges.
NOTE: Because the PDR 3500 can draw up to 10 amps
during high-power transmission, there can be a
significant drop in voltage through a DC power cable.
If the station reverts to low-power mode while
operating off of DC, a shorter DC cable may help.
5. In DC-powered applications, the Over Air and Over Wireline
Alarm Tone fields specify whether the station will transmit an
alert tone when a low-voltage condition is detected. Setting
either of these fields to “ENABLED” will cause the station to
periodically transmit a beep via that path (air or wireline) while
operating at the Battery Backup power setting. See the
Interpreting Alarm Tones heading of the Troubleshooting
section of this manual for more information.

under the Channel Information heading.
For instructions on performing Rx or Tx Wireline Alignment, please
refer to the Quantar RSS User’s Guide (68P81085E35).
