Operation Mode  
 It is receiving state when power standby ; When the data port detects a data input, the radio automatically transmits. After the data transmission, it turns to receiving state.
   
Notes  
1Adopt small rippled and stablized power supply or battery. 
2The antenna should be kept away from the power supply. 
3Power supply capacity should meet 5/12V/500mA 
4The distance between the experimental stations should be farther than 5 meters 
5Install the Antenna in high place, no shelter within 30 meter coverage 
Tips: After the radio connected to the antenna, the distance between the radios should be more than 10 meters to avoid too strong signal caused blocking!

Notice:


1Use the min. grain wave and high anti-jamming switch power or batteries;

2The power capacity must meet D.C. 5~12V,more than 800mA output current

3The space between the experiments Radio should be more than 5m. The antenna should span on the high to increase the distance of electric wave. It is important for using shortwave communication equipment in the city.

4After connecting the antenna to the Radio, the space between the Radios should more than 10m, so avoid signal backup.

5The antenna plywood should nip in the connection inside the antenna, but not nip the antenna projectile, so avoiding the performance of the antenna.

High frequency cable don’t come down directness, circle a circuit and fix up it on the frame for the best.
