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. To upgrade quality, any electrical or mechanical parts and internal circuits are subject to change without notice or obligation. ORDERING PARTS REPAIR NOTES Be sure to include the following four points when ordering 1. Make sure a problem is internal before disassembling replacement parts: the transceiver. 2. DO NOT open the transceiver until the transceiver is 1. 10-digit order numbers disconnected from its power source. 2. Component part number and name 3. DO NOT force any of the variable components. Turn 3. Equipment model name and unit name them slowly and smoothly. 4. Quantity required 4. DO NOT short any circuits or electronic parts. An insulated tuning tool MUST be used for all adjustments. 5.
