Caring for Your Radio
 If you experience hearing discomfort, ringing
in your ears, or muffled speech, you should
stop listening to the radio through your
headset or earpiece and have your hearing
checked by your doctor.
See www.motorola.com/hearingsafety for more
information.
 Your radio casting
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
leak paths into the
radio and the
radios
submergibility will
be lost.
 (For APX 4000 R
Radios Only)
Your radio is designed to be submerged to a
maximum depth of 6 feet, with a maximum
submersion time of 2 hours. Exceeding either
