Instructions

System connection

• Please connect the power adapter in the box with the “POWER IN” connector of the receiver.
• Select “LINE OUT” / “MIC OUT A / B” to audio as a required system.
• Install the receiver antennas to the “ANT A / B” on both sides of the receiver rear panel.

Note: Plug the power adapter into an AC grid that meets the specifications.

Install the battery

• Hand-held transmitter: Unscrew the battery cover counterclockwise, insert two standard AA5 batteries according to the battery according to the “+” and “-” polarity signs in the battery compartment, and screw the battery cover on.
  • Waist-mounted transmitter: Pull the battery compartment cover hook downwards to open the battery cover, insert two standard AA5 batteries into the battery according to the “+” and “.” polar signs in the battery compartment, and close the battery cover.

On / Off

• Receiver: Set the boat shape to the “I” position, the power indicator light is on, and the boot is successful; otherwise, it is turned off.
• Handheld transmitter: press the switch for 2 seconds to turn on, and press it for 2 seconds to turn off under normal use. 4. Handheld transmitter frequency synchronization setting
• Press the 2 key (SELECT) to search the receiver channel (when the LED search symbol stops turning, it means the automatic search is completed).
• Turn on the power of the transmitter, point the infrared (IR) port at the infrared transmission window of the receiver, and hold down the 6 key until the transmission and reception are synchronized (the receiver LCD screen will display the RF signal and intensity)

Receiver automatic/manual frequency search

• Turn on the phone
• In the current interface, press 3 to jump down, and press 4 to jump up, each step is 500K.
  • Tip: Transmitting equipment such as mobile phones and two-way radios are prone to interfere with this system. When using them, try to stay away from such equipment and avoid potential sources of interference
  • Tip: The setting method of the A / B channel of this system is the same
  • Special Note: Use the following techniques to improve the performance of this system. The transmitter and antenna maintain an unobstructed straight relative position. Do not place the receiver near metal surfaces or near any digital equipment.
