Cleaning
ALWAYS turn OFF the power, unplug the power cord and remove the battery before
cleaning.
The exterior of the system and display may be wiped with a clean, soft, and lint-free cloth.

the cloth and wipe.
An air gun is recommended for cleaning water and dust. For salty water please clean with
fresh water then blow-dry with an air gun.
