Instructions:
Accessories Introduction:
One power amplifier, one power cord, one output cable, one input cable

Appearance Introduction:
- Aluminum heat sink, 2pcs fans, fan grille protection, stainless steel shell, hexagonal screws, silicone feet, laser screen printing
- Small size, easy to carry, sturdy stainless steel housing, compact design

Interface Introduction:
- Input port, antenna port, power supply port, switch (gear selection), signal indicator has 4 grids
 
Introduction of Switch and Gears:
- Gear 1: magnify approximately 10 times, input 1W and output 10W; input 2W and output 20W, and so on.
- Gear 2: about 20 times magnification, input 1W and output 20W; input 2W and output 40W, and so on.
- Attention: When the power is high, the output power will be compressed. It means that it is not the input of 5W and then the output is 100W.
- OFF Gear: The power amplifier is in the through state, and the sending and receiving are not amplified.
 
Indicator Introduction:
- When it is on, it means that the power amplifier is in amplifying state;
- The more lights lit, the greater the input signal;
- Input power indication range, 1 light lit at 0.5W, 3W full mark, minimum 0.1W can be driven.
 
Introduction of Automatic Speed Regulation Fan:
At room temperature, the fan speed is very low and there is basically no sound. As the temperature of power amp increases, we can see that the speed of the fan is gradually increasing, about 800 rpm, and there is still no noise. After the power amplifier is full power for 5 minutes, the fan starts to run at full speed, and the speed is about 1800 rpm. If it does not transmit, after the temperature of the power amplifier drops, the fan speed will return to about 800 rpm.
 
Support Modes:
- Analog format: For NFM, AM
- Digital system: For P25, C4FM, NXDN, D-STAR
 
Wiring Test:
Get a handset radio, a power meter, connect the power cord, input cord, output cord, and then power on to test.
 
Applications:
1. When there is only a handset radio and high power is needed.
2. Digital handset radio require high-power and long-distance communication.
3. Self-driving team tour, on-site command, relay station.
