Operating Instructions
1. LCD screen on the transmitter and the RF
level/indicator shown on the receiver will be lit
when the microphone is turned-on, denoting
normal status. A blank LCD screen maybe due
to an incorrect battery polarity orientation.
2. The audio level or indicator show on the receiver
will be lit when there is audio line or
microphone input from the transmitter.
Caution
Remove the batteries if unused for a long period of
time to prevent battery leakage, corrosion and
causes damage to electronics.

Battery Status
10 0% 80 % 40 % 10 % 0%
Indicates the power remaining in the transmitter
battery. When the battery has less than 10% power
remaining it must be replaced or recharged. If an
under voltage condition continues, the LCD will show
“Poff” and the system will shut down to prevent
being overly discharged.
“Poff” - Power Off :
When the power switch is turned off, the LCD will
show “Poff” (for Power Off) first and then the
system will shut down and no further messages will
be displayed.
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.
