• If an accessory is not attached to the radio, ensure that the accessory connector cover is
attached to the radio side accessory connector.
• If the radio is submerged or exposed to a high force water spray, such as from a hose,
remove the accessory or accessory connector cover immediately and ensure that no water
is forced into the accessory connector/radio interface. Rinse and dry the area and re-attach
the accessory or accessory connector cover if leakage occurs.
• If the radio is exposed to a corrosive environment, such as salt water or corrosive gases
or liquids, rinse and clean the radio immediately to prevent damage to radio materials,
especially plated surfaces. Remove the battery and the antenna before cleaning.
• Do not disassemble the radio as you could damage radio seals and result in leak paths into
the radio. Any radio maintenance should be performed only by a qualified radio technician.
• Only Underwriter Laboratory (UL) approved service centers can open and service UL
certified radios. Opening or repairing at unauthorized locations invalidates hazardous
location rating of the radio.
• Do not pound, drop, or throw the radio unnecessarily.
• When cleaning the radio, do not use a high-pressure jet spray as this may exceed the depth
pressure and cause water to leak into the radio.
