“You’re suffocating me!”
That’s what your AN/TRC-190 line-
of- sight (LOS) multichannel radio ter-
minal and your AN/TRC-191 radio ac-
cess unit (RAU) would tell you if they
could talk.
The LOS radio terminal and the
RAU need that cooling airflow inside
the shelter to prevent temperatures
from climbing and equipment from
overheating.
Here’s how to make sure your shel-
ters breathe a little easier if you don’t
have air conditioning or if it’s not up
and running:
Door Vent
Hold down the heat by opening the
vent cover in the shelter door to let in
fresh air. Open the cover wider in the
hot season.
Mobile Subscriber Equipment . . .
Battery Box Vent
Make sure you open the exhaust vent
for the lead-acid battery box. Also make
sure the battery box fan is running. If
it’s not, report it. The exhaust vent and
the fan work together to draw fumes
away from the batteries to the outside
of the shelter. Trapped inside, those
fumes need only a spark to ignite.
The fans not only draw warm air out
of the shelter, they also help get rid of
dust.
Never pile gear in front of the fans.
That blocks the airflow.
Inspect the door and fan vent filters
for dirt, bugs and debris. Clogged fil-
ters block airflow. Remove filters and
rinse them in clean water. Let them air
dry.

Fan Vents
Likewise, open the fan vent covers

to ON to get the ventilation fans
working.
