Safety & Warnings
NEVER connect the transceiver to an AC outlet or to a DC power supply that uses more than 9 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.
When servicing intrinsically safe versions of the IC-F35 / IC-F45, the following conditions must be met. Failing to satisfy any of these conditions will invalidate the INTRINSICALLY SAFE certification:
1. Servicing the transceiver should only be undertaken by suitably qualified personnel in a non-hazardous area. Never attempt to remove the case in a hazardous area.
2. ONLY the approved battery, ICOM’s CM-140, may be used.
3. USE ONLY safety critical components as specified in the parts list (SECTIONS 7), should replacement of any item be necessary.
Make sure a problem is internal before disassembling the transceiver.
DO NOT open the transceiver until the transceiver is disconnected from its power source.
DO NOT force any of the variable components. Turn them slowly and smoothly.
DO NOT short any circuits or electronic parts. An insulated tuning tool MUST be used for all adjustments.
DO NOT keep power ON for a long time when the transceiver is defective.
DO NOT transmit power into a signal generator or a sweep generator.
ALWAYS connect a 40 dB to 50 dB attenuator between the transceiver and a deviation meter or spectrum analyzer when using such test equipment.
READ the instructions of test equipment thoroughly before connecting equipment to the transceiver.
