Quick Setup Guide(Download Manual):

1. Connect your antenna to the ANT port.
2. Connect your radio to the TRX port and adjust the output power of your radio to about 2W.
3. If necessary, connect the ACC port to your radio’s ACC port.
4. Connect one end of the supplied DC cable to a DC power supply(13.8V is recommended) or a battery, with the other end to the amplifier’s DC power port.
5. Put your radio into TX mode and observe the output level of your power amplifier. If the output power level is lower than 50W, please increase the output power of your radio, vice versa. But in any case, do not set the output power of your radio above 5W.
6. Power protection may be activated when an antenner tuner is used. Do not use the amplifier while an antenna tuner is in tuning.
