MANPACK BATTERY NEAR END OF ITS LIFE. Transmit as little as possible. Use
the lowest RF switch setting which still Jets you communicate. When possible, set
RT FCTN to
VEHICLE SYSTEM BATTERY DEAD. If you have a dismount radio, remove an RT
from its mounting adapter (or power supply adapter): then assemble a manpack
HOLD UP BATTERY (HUB) DEAD. If presets are cleared when the power is cut off,
the HUB might be dead. If this happens, re-load the presets: then keep the RT FCTN
switch set to an operating position (do not set FCTN switch to
on mounting adapter or power supply adapter (vehicular radios) set to ON (do not
set CB1 to OFF).
VEHICULAR ANTENNA BROKEN. Try communicating on a higher SC frequency. If
you have a dismount radio, remove the antenna cable from the RT ANT connector;
then connect the manpack antenna to the ANT connector.
CONTROL-MONITOR FAULTY. Maintain radio operation by local control. Set the
RT FCTN switch to SQ ON. Set all other controls as needed.
EXPOSURE TO NUCLEAR RADIATION. If you cannot contact another station after
a nuclear event, do the following steps:
a. Reset RT: Set FCTN to
then to SQ ON.
b. Test RT. Set RT FCTN to TST. Check displays for proper indications (page 5-4).
c. Check FH sync time. Press l l l /TIME button three times and note if the seconds
are running. If they are, go on to step d. If they arent, go on with steps c(1)
l Manpack: Check battery life condition. Remove battery
from back of RT and reinstall it. Reset battery life condition.
l Vehicular: Set mounting adapter (or power supply adapter) CB1 to OFF;
then back to ON.
FH operators: Set FH sync time. Use the nets time standard. If a time
standard is not available, contact NCS; use late entry or cue proce-
d. Communicate. Set RT FCTN to normal operating position; then contact the de-
FILL CABLE DAMAGED. Substitute vehicular cable between RT AUD/DATA connec-
tor and mounting adapter.
