remaining it must be replaced or recharged. If an
under voltage condition continues, the LCD will
show “OFF...” and the system will shut down to
prevent being overly discharged.

ERR: Error Code

If the LCD displays “ERR” after turning on the
power, it indicates the operation is not correct. The
error codes are as follows:

ROM-ER → Transmitter does not have the initial

data so the microphone is completely
dead and cannot be programmed.

ERROR1 → Failure on RF circuitry, frequency

cannot be programmed.

NO----OR3 → Frequency to be programmed into

the transmitter exceeds the highest
frequency of the designated
frequency band of the transmitter.

NO----OR4 → Frequency to be programmed into

the transmitter exceeds the lowest
frequency of the designated
frequency band of the transmitter.

**Note:

NO----OR3 and NO----OR4 will not change the

transmitter's original frequency and the

transmitter will still operate normally with the

error message on display. To remove the error

message from the display panel, please switch

off the transmitter and switch it on again.

MUTE Control Set-Up

MUTE control enables audio to be muted or

un-muted temporarily.

NOTE: Plug in the device before power on the

High Frequency Bypass

a. When other microphones are in use, some

changes may be needed to another microphone
before adding it to the system in order to avoid
high frequency interference, as illustrated in
diagram (1).

b. When a high frequency radio wave causes

interference, it normally affects the system by
generating a persistent noise or by deteriorating
the frequency response. In an effort to
ameliorate these problems, a 330PF bypass
condenser can be added on the cartridge as
shown in diagrams (1) and (2). If this method is
not possible, another option is to add a bypass
condenser on the 4-pin XLR connector as shown
in diagrams (3) and (4).

Battery Removal and Installation

! Pushing down both snap locks on the sides to

open battery compartment cover. Take out the

one

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.

(Figure 4)(Figure 3)

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.

31

Dispose of any unusable devices or batteries
responsibly and in accordance with any
applicable regulations.

Disposing of used batteries with domestic waste
is to be avoided!

Batteries / NiCad cells often contain heavy
metals such as cadmium(Cd), mercury(Hg) and
lead(Pb) that makes them unsuitable for
disposal with domestic waste. You may return
spent batteries/accumulators free of charge to
recycling centres or anywhere else batteries/
accumulators are sold.

By doing so, you contribute to the conservation
of our environment!
