Safety & Warnings
Use only the specified AC voltage described on the AC power socket. Other voltages may cause repeater damage or personal injury. Do not expose the repeater to rain, snow, or any liquids. Do not reverse the polarities of the power supply when connecting the repeater. Do not apply an RF signal of more than 20 dBm (100 mW) to the antenna connector, as this could damage the repeater’s front end. Ensure a problem is internal before disassembling the repeater. Do not open the repeater until it 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 repeater is defective. Do not transmit power into a signal generator or a sweep generator. Always connect a 40 dB or 50 dB attenuator between the repeater and a deviation meter or spectrum analyzer when using such test equipment. Read the instructions of test equipment thoroughly before connecting equipment to the repeater.
