ERR Message
Battery Status
When the battery has less than 10% power
remaining, display will start flashing and
batteries must be replaced immediately. If an
under voltage condition continues, the LCD will
show “OFF...” and the system will shut down.
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.

80%
60%

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.)
Power Button
Turn the power switch to ON position where
transmitter will be activated and LCD will lit up.
Turn the power switch to OFF position to shut
down the transmitter.
When the power switch is turned off, the LCD
will show “OFF...” (for Power Off) first and then
the system will shut down and no further
messages will be displayed.
“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.

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.

1. Performer should avoid holding the microphone over
or near the antenna section as this will deteriorate
transmission efficiency. Severe deterioration if

both hands.

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.
Disposal
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!
