Put the TX antenna 150cm far from RX antenna, power on, use soft label or hard

tag to test until the RF4200 system alarms, the buzzer sounds “di...di...di.....”and also

the leds on rx board flashing, then it means the system is working normally. The alarm

sound volume is controlled by P201 on the RX board. The volume has low, medium

and high optional. Factory setting is medium. Testing the 4*4 soft label, the detection
