OPERATION IN BAD WEATHER. If you are operating your radio in unusual weather,
do the PMCS more often. Keep your radio controls as clean as you can (especially
the keyboard and display). Keep your radio shaded from the sun as much as possible
when operating in a hot climate.
Your radio should operate under any of the following conditions:
l Moist heat (tropics)
l Ocean spray
l Sand or dust storms
l Dry heat (deserts)
l Salty air
OPERATION IN LOW TEMPERATURES. Keep ice off of your equipment. Cables may
become brittle if they are exposed to cold weather. Do not bend them at sharp
angles. Make sure the vehicular charging system is strong enough for you to commu-
nicate. Batteries lose their power when they get cold. lf you have a dismount radio,
check the battery life condition more often. Log battery life condition each time you
assemble or disassemble manpack.
If you have SC or FH presets in the RT, do not set FCTN
if the temperature drops below +20° F. You may cause the presets
to be cleared by shutting off RT power.
Your radio has been tested and it is water tight. You do not have to make special
preparations for water crossing. After fording, remove any mud or other foreign mat-
ter as soon as you can.
