Anleitung Zusammenfassung
USA IC-M802 Canada CAN Other OTH To upgrade quality, any electrical or mechanical parts and internal circuits are subject to change without notice or obligation. NEVER connect the transceiver to an AC outlet or to a DC power supply that uses more than 16 V. This will ruin the transceiver. DO NOT expose the transceiver to rain, snow or any liquids. DO NOT reverse the polarities of the power supply when connecting the transceiver. DO NOT apply an RF signal of more than 20 dBm (100 mW) to the antenna connector. This could damage the transceiver’s front end. ORDERING PARTS REPAIR NOTES Be sure to include the following four points when ordering 1. Make sure a problem is internal before disassembling the replacement parts: transceiver. 2. DO NOT open the transceiver until the transceiver is disconnected from its power source. 1. 10-digit order numbers 2. Component part number and name 3. DO NOT force any of the variable components. Turn them slowly and smoothly. 3. Equipment model name and unit name 4. Quantity required 4. DO NOT short any circuits or electronic parts. An insulated tuning tool MUST be used for all adjustments. 5. DO NOT keep power ON for a long time when the trans< SAMPLE ORDER> ceiver is defective. 1110004080 S.IC .PC2709T IC-M802 MAIN UNIT 5 pieces 6.
