System Setup

1. Connect the included AC power supply to the rear of the receiver and turn on the receiver.
2. Standard Display
   The standard display shows the preselected group, channel, RF power level.
   

Group
Push the SET button one time, the GROUP blink, Push the up and down buttons to set the desired group (01-10), Press SET again to confirm.The display will return to standard after a short period of time of non-activity automatically.
NOTE: Each group 01-10 consists of 10 channels, each corresponding to a specific frequency.

Channel
After the step of setting group, press the SET again, the CHANNEL blink. Push the up and down buttons to set the desired channel (01-10), Press SET again to confirm. The display will return to standard after a short period of time of non-activity automatically.

RF Power
After the step of setting channel, press the SET again, the POL “4” blink ( as below picture1). Push the up and down buttons to set the desired RF Power level (1-4), Level 1 shows two lines of signals, the corresponding RF power is 5mW; Level 2 shows four lines of signals, the corresponding RF power is 10mW; Level 3 shows six lines of signals, the corresponding RF power is 30mW; Level 4 shows full lines of signals, the corresponding RF power is 100mW ( as below picture2). And when the LCD display in the standard status, it can push the up and down buttons to set the desired RF Power level.
NOTE: The larger RF power, the Longer distance.

IR Synch
Anytime press the SET button and hold for 1 second, the receiver start to send the infrared signals (as below picture ), then put the belt- pack receiver’s IR port close to the Transmitter/Main unit’s IR port , the receiver has to be synchronized to the same frequency (group and channel) before using.
Note: The receiver have to be turned off and return- on while transmitter send infrared signals. After a successful sync, the receiver’s blue LED RF indicator lights up.
