EXPLICIT DEFINITIONS

WORD

DEFINITION

RWARNING

Personal injury, fire hazard or electric

shock may occur.

 

 

CAUTION

Equipment damage may occur.

NOTE

If disregarded, inconvenience only. No risk

of personal injury, fire or electric shock.

 

 

 

The IC-R8500 complies with essential require- ments of the 89/336/EEC directive for Electromagnetic Compatibility. This compliance is based on conformity with the ETSI specification prETS300

684 (EMC product standard for Commercially Available Amateur Radio Equipment).

PRECAUTIONS

RINDOOR USE ONLY! NEVER expose the IC-R8500 or AC adapter to rain, snow or any liquids.

RNEVER connect the receiver to an AC outlet directly. This may pose a fire hazard or result in an electric shock. Always use the supplied AC adapter or connect to a 13.8 V DC power source.

RNEVER connect to an AC outlet that exceeds the suggested voltage for each AC adapter version. This could cause a fire or ruin the AC adapter and/or receiver.

RNEVER use non-rated fuses. Non-rated fuses could cause a fire or ruin the receiver.

NEVER let metal, wire or other objects touch any internal part or connectors on the rear panel of the

receiver. This will cause electric shock.

AVOID using or placing the receiver in areas with tem- peratures below –10°C (+14°F) or above +50°C (+122°F).

AVOID placing the receiver in excessively dusty envi- ronments or in direct sunlight.

AVOID placing the receiver against walls or putting anything on top of the receiver. This will obstruct heat dissipation.

RESPECT other people’s privacy. Information over- heard but not intended for you cannot lawfully be used in any way.
