Safety & Warnings
NEVER connect the receiver to an AC outlet or to a DC power supply that uses more than 16 V. This will ruin the receiver. DO NOT expose the receiver to rain, snow, or any liquids. DO NOT reverse the polarities of the power supply when connecting the receiver. DO NOT apply an RF signal of more than 20 dBm (100 mW) to the antenna connector as this could damage the receiver’s front end. Ensure a problem is internal before disassembling the receiver and DO NOT open the receiver until it is disconnected from its power source. DO NOT force any 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 receiver is defective. Read the instructions of test equipment thoroughly before connecting equipment to the receiver.
