Cleaning Methods

Clean the Communications Unit regularly to keep it in optimum operating condition.
• For daily cleaning, use a soft, dry cloth.
• If dry wiping does not remove all of the dirt, use a diluted mild detergent (2%) and wring out the cloth
thoroughly before wiping.
• Leaving rubber items, plastic items, or tape on the Unit for an extended period of time may leave
stains. Remove any such items from the Unit when cleaning.
Precautions for Correct Use
Never use benzine, paint thinner, or any other volatile cleaning solutions or chemical wash cloths
for cleaning. These products can damage the coating on the Unit.
