Sec 2: 2-2
2.2.1 APX 7000XE Radios Only
If the radio battery contact area has been submerged in water, dry and clean the radio battery
contacts before attaching a battery to the radio. Otherwise, the water could short-circuit the radio.
If the radio has been submerged in water, shake the radio briskly so that any water that is trapped
inside the speaker grille and microphone port can be removed. Otherwise, the water will decrease
the audio quality of the radio.
• The APX 7000XE radio has a vent port that allows for pressure
equalization in the radio. Never poke this vent with any objects, such as
needles, tweezers, or screwdrivers. This could create a leak path into the
radio and, the radio's submergibility will be lost.
• The pressure equalization vent is located under the main speaker grille
near the top left side. Never obstruct or cover the small opening on the top
left with any object, including a label. Ensure that no oily substances come
in contact with this vent.
• APX 7000XE radio is designed to be submerged to a maximum depth of
six (6) feet, with a maximum submersion time of 2 hours per U.S.
MIL-STD. Exceeding either maximum limit may result in damage to the
radio. For specific U.S.
MIL-STD details, see Section
page 2:8-33.
