2、rETS300 684 (EMC product standard for Commercially Available Amateur Radio Equipment). UNPACKING PRECAUTIONS IMPORTANT READ THIS INSTRUCTION MANUAL CAREFULLYbefore attempting to operate the receiver. SAVE THIS INSTRUCTION MANUAL. This instruction manual contains important safety and oper- ating inst

3、ructions for the IC-R8500. EXPLICIT DEFINITIONS RINDOOR USE ONLY! NEVER expose the IC-R8500 or AC adapter to rain, snow or any liquids. RNEVERconnect the receiver to an AC outlet directly. This may pose a fi re hazard or result in an electric shock. Always use the supplied AC adapter or connect to a

4、 13.8 V DC power source. RNEVERconnect to an AC outlet that exceeds the suggested voltage for each AC adapter version. This could cause a fi re or ruin the AC adapter and/or receiver. RNEVERuse non-rated fuses. Non-rated fuses could cause a fi re or ruin the receiver. NEVERlet metal, wire or other o

5、bjects 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 10C (+14F) or above +50C (+122F). AVOID placing the receiver in excessively dusty envi- ronments or in direct sunligh

6、t. AVOID placing the receiver against walls or putting anything on top of the receiver. This will obstruct heat dissipation. RESPECT other peoples privacy. Information over- heard but not intended for you cannot lawfully be used in any way. i Accessories included with the IC-R8500: Qty. AC adapter (

NOISE BLANKER/AFC SWITCH NB/AFC Activates the noise blanker function or automatic fre- quency control function. The noise blanker is used for removing pulse-type noise when SSB, CW or AM mode is selected (p

19、.15). The automatic frequency control tunes the displayed fre- quency automatically when an off-center frequency is re- ceived. It activates when FM or WFM is selected (p.14). AUDIO FREQUENCY GAIN CONTROL AF GAIN (p. 13) Rotate clockwise to increase the audio output; rotate counterclockwise to decre

20、ase the audio output. AUTOMATIC GAIN CONTROL AGC (p. 15) Toggles the time constant of the AGC circuit be- tween “slow” and “fast.” When “fast” is selected, “AGC-F” appears. Cannot be used in FM or WFM modes. SQUELCH CONTROL SQUELCH (p. 14) Varies the squelch threshold level (to mute noise when recei
