ERR Message
!When “ERR” appears in the display it indicates
that an operational error has occurred. Please
refer to the following codes to diagnose which
error you are experiencing.
ERR no01 EEPROM is not being programmed or
internal data error.
ERR no02 For testing only.
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.
!“Channel” Only : If “Channel” only is
displayed, it means that you are using a
frequency which is not pre-programmed.

Battery Removal and Installation
!Pushing down both snap locks on the sides to
open battery compartment cover. Take out the
two batteries. (Figure 3)
!Insert one charged 18500 rechargeable battery
into the battery compartment according to the
correct polarity (- and +) as shown in (Figure 4)
. Then close the battery compartment cover
tightly.
Caution
Remove the batteries if unused for a long period of
time to prevent battery leakage, corrosion and
causes possible damage to electronics.

Caution
Note: Transmitter cannot be powered on with
charged battery.
Method 1:
a. Ensure battery is inserted correctly with + top
side.
b. 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.
c. 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.
