OPERATION (continued)
AUTO FREQUENCY SETTING
1. Select one of the microphones and power it ON.
2. On the receiver, press the
SCAN
button for channel A or B and the receiver will begin to scan for the best
available frequency.
3. After the receiver completes its search and sets the frequency on the LED Control Display, hold the desired
microphone close to the wireless receiver so both the infrared receiver on the microphone and the infrared
transmitter on the wireless receiver are in a direct unobstructed line of sight. Press the
ACT
button for the
selected frequency to be transmitted to the microphone.
4. Confirm the desired frequency was set by pushing the power button on the microphone to toggle between
CH
and
MHz
on the LED display. If successful, the
CH
and
MHz
on the receiver channel should match on the
microphone.
5. Repeat this process for the other channel and microphone or repeat this process again if there are any
issues.
6. Adjust the volume control dials for each channel (A&B) accordingly and test.
