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.

General Tips for Improving System
Performance
1. Performer should avoid holding the microphone over
or near the antenna section as this will deteriorate
transmission efficiency. Severe deterioration if
performer directly covers up the antenna section with
both hands.
2. Many performers tend to hold the microphone by the
top grille. Unfortunately, this position seriously
degrades both the sound quality and directionality of
a microphone. Even the most expensive microphones
will have its original sound quality compromised by
this method. Grabbing a microphone by the grille will
isolate the capsule's acoustic resonance circuit and or
change the capsule resonator's frequency. This
results in an inferior performance in both frequency
response and the separation of directionality. In
addition, a palm's sound-focusing effect will tend to
strengthen resonances in certain frequencies and can
cause unwanted echo.
3. A proper technique is required for using directional
microphones because the distance between the
microphone and your mouth has a significant impact
on sensitivity and performance. There is an inverse
relationship between microphone sensitivity and the
distance from the mouth to the microphone.
Consequently, performers with a ''weaker'' sound
level cannot expect to hold the microphone too far
away from their mouth and compensate by turning
up the amplifier volume to increase the sound level
as this can easily cause echo or feedback. In
contrast, performers with a ''louder'' sound level
should not hold the microphone too close as this can
easily result in distortion by causing the amplifier
system to be overloaded.

4. Furthermore, a large-diaphragm directional
microphone has a very distinct proximity effect.
When the microphone is close to the mouth, the
bass response is strengthened as the distance gets
closer. Therefore, if a performer's sound is
insufficient in bass, they can hold the microphone
closer and use the proximity effect to help
compensate for the lower bass level. Conversely, if a
performer's voice is too heavy in the bass register,
increasing the distance between the microphone and
their mouth will decrease the proximity effect and
reduce the bass response, thus making their voice
become clearer and brighter.
5. It is recommended to keep the grille and sponge
windscreen clean to avoid any substance blocking the
proximity effect of the microphone.
Notes
1. Refer to actual product in the event of product
description discrepancy.
2. Frequency range and maximum deviation comply
with the regulations of different countries.

WARNING
1. FOR OUTDOOR USE:
To reduce the risk of fire or electric shock, do not
expose this apparatus to rain or moisture.
2. UNDER WET LOCATION:
Apparatus should not be exposed to dripping or
splashing and no objects filled with liquids, such as
vases should be placed on the apparatus.
3. SERVICE INSTRUCTIONS:
CAUTION - These servicing instructions are for use by
qualified service personnel only. To reduce the risk of
electric shock, do not perform any servicing other than
that contained in the operating instructions unless you
are qualified to do so.
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!
