Handling Precautions
The MOTOTRBO Series Digital Portable radio meets
IP57 specifications, allowing the radio to withstand
adverse field conditions such as being submersed in
water.
• If the radio has been submersed in water, shake the
radio well to remove any water that may be trapped
inside the speaker grille and microphone port. Trapped
water could cause decreased audio performance.
• If the radio’s battery contact area has been exposed to
water, clean and dry battery contacts on both the radio
and the battery before attaching the battery to the
radio. The residual water could short-circuit the radio.
• If the radio has been submersed in a corrosive
substance (e.g. saltwater), rinse the radio and battery
in fresh water then dry the radio and battery.
• To clean the exterior surfaces of the radio, use a diluted
solution of mild dishwashing detergent and fresh water
(i.e. one teaspoon of detergent to one gallon of water).
• Never poke the vent (hole) located on the radio chassis
below the battery contact. This vent allows for pressure
equalization in the radio. Doing so may create a leak
path into the radio and the radio’s submersibility may
be lost.
• Never obstruct or cover the vent, even with a label.
• Ensure that no oily substances come in contact with the
vent.
• The radio with antenna attached properly is designed to
be submersible to a maximum depth of 1 meter (3.28
feet) and a maximum submersion time of 30 minutes.
Exceeding either maximum limit or use without antenna
may result in damage to the radio.
• When cleaning the radio, do not use a high pressure jet
spray on the radio as this will exceed the 1 meter depth
pressure and may cause water to leak into the radio.
Do not disassemble the radio. This could
damage radio seals and result in leak paths into
the radio. Radio maintenance should only be
done in service depot that is equipped to test
and replace the seal on the radio.
