WARNING
Operation of the AN/PRC-90 without adequate rf shielding is prohibited
except during a bonafide emergency situation. Keep the function switch in
the OFF position at all times when not in emergency use and operate the
VOL control in the minimum position during voice transmissions. Failure
to observe these precautions will shorten battery life and could result in
equipment failure or disrupt actual search missions. If the unit is issued in
a sealed container, do not break the seal until the emergency conditions
have stabilized.
