1 INSTRUCTION MANUALiC- r8500 COMMUNICATIONS RECEIVERThe iC-r8500 complies with essential require-ments of the 89/336/EEC directive forElectromagnetic Compatibility. This compliance isbased on conformity with the ETSI specification prETS300684 (EMC product standard for Commercially AvailableAmateur Radio Equipment).UNPACKINGPRECAUTIONSIMPORTANT READ THIS INSTRUCTION MANUALCAREFULLY before attempting to operate THIS INSTRUCTION MANUAL. Thisinstruction manual contains important safety and oper-ating instructions for the DEFINITIONSRINDOOR USE ONLY!

2 NEVER expose theIC-R8500 or AC adapter to rain, snow or any the RECEIVER to an AC outletdirectly. This may pose a fire hazard or result in anelectric shock. Always use the supplied AC adapter orconnect to a V DC power to an AC outlet that exceeds thesuggested voltage for each AC adapter version. Thiscould cause a fire or ruin the AC adapter non-rated fuses. Non-rated fusescould cause a fire or ruin the metal, wire or other objects touch anyinternal part or connectors on the rear panel of thereceiver. This will cause electric using or placing the RECEIVER in areas with tem-peratures below 10 C (+14 F) or above +50 C(+122 F).

3 AVOID placing the RECEIVER in excessively dusty envi-ronments or in direct placing the RECEIVER against walls or puttinganything on top of the RECEIVER . This will obstruct people s privacy.
