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 2000/ APX 4000 (Two Knobs) 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 adjacent to the battery contact
opening of the main chassis. Never touch the equalization vent. Ensure
that no oily substances come in contact with this vent.
• The APX 2000/ APX 4000 (Two Knobs) 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.
