ERR no03 The frequency you want to program is above the switching bandwidth of the transmitter. Use a receiver with an appropriate frequency group. (At this time the microphone is still operating and the frequency remains unchanged. To clear the displayed "ERR" message, switch the handheld transmitter off and on again.) ERR no04 The frequency you want to program is below the switching bandwidth of the transmitter. Use a receiver with an appropriate frequency group. (At this time the microphone is still operating and the frequency remains unchanged. To clear the displayed ERR message, switch the handheld transmitter off and on again.) Group & Channel : When both the group and channel numbers are displayed, it means that you are using the pre-programmed frequency of the receiver.

Transmitters Charging 18500 Charging Caution Note: Transmitter cannot be powered on with charged battery. Method 1:
a. Ensure battery is inserted correctly with + top side. b. c. If battery is inserted correctly it could be due to self battery protection mechanism. Insert the transmitter into the charger to re-charge for 10-20 seconds to wake-up the battery. It should work. If charger cannot be used, reverse the battery insertion for 10-20 seconds, wake up the battery with correct polarity. It should work. Method 2:
a. Power off the transmitter before open the hinged cover. Press battery protection circuitry reset button once to wake-up battery. Power on the transmitter.
