Ascertain the power is turn "ON" to see battery
status.
! Normal Battery: Red indicator is on for a
second and goes off after power on.
! Weak Battery: Red indicator stays on
continuously after power on. Recharge or
insert a new recharged battery.
! No red indicator light: battery is
completely drained or polarity inserted
incorrectly.

! Remove grill in counter clock direction.
! Press and hold both sides of microphone
capsule module and remove gently.
! Ascertain the battery is inserted according to its
correct polarity. A click is heard once correctly
inserted and grill can be closed properly. No
click is heard and grill cannot be closed
properly if battery is inserted with the wrong
polarity.
NOTE: Transmitter cannot be powered on with a
charged battery.
a. Check for correct polarity insertion
(+ facing up).
b. If inserted with correct polarity and still
cannot be powered on it could be due to
battery protection mechanism is in effect.
Insert the whole transmitter back to the
battery charger for 10 seconds to “wakeup” and power on again.
c. If battery charger is not used, reverse
battery polarity for 10 seconds then reinserted with correct polarity to wake up
the battery. Power on again.
MP-80 Battery Charger (Optional)
MP-80 Charger charges both transmitters and
18500 rechargeable batteries.

Rear cap has an On/Off switch protection
The patented color rear cap serves two purposes; it
provides easy channel identification and protects
the on/off switch. It is designed to allow the on/off
switch to either be exposed or concealed as
desired. You can avoid unintended switching off of
the microphone by rotating the color rear cap 180
degrees to cover the on/off switch completely. The
cap can be removed by gripping it firmly and
pulling; be sure to push it firmly into place when
replacing it on the microphone.
NOTE: During microphone usage, the color rear cap
must be installed.
Press both sides and pull out to remove rear cap

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.

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!
