13. OPERATIONAL HINTS
• When the transmitter user moves in a facility, signal dropouts (momentary losses of signal reception) may
be encountered. These dropouts are caused by the building's architectural designs or materials which block
the travel of or reflect the radio signal. If this occurs, the user needs to change locations for better signal
reception.
• Confirm the good line of sight between the transmitter and the receiver. Do not place the large obstructions
(ex. Concrete walls or large metal obstructions) between the transmitter and the receiver. In addition keep
the receiver away from the metallic beams and obstructions as these can adversely affect the antenna pick-
up pattern and induce the interference.
• Set the transmitter AF gain so the receiver VU indicates 0 db with occasional peaks to +6 dB.
• Hold the microphone within 20cm from the sound source. Move the microphone closer for a warmer sound
increased. And do not cover the grille with hand.
• Keep your mouth 15 – 20 cm away from the lavalier microphone for the best possible sound reproduction. In
case of the Omni-directional response, it will pick up sounds from all directions. It is better that the
microphone is placed closer to the sound source. Take care not to bring your mouth too close to the
microphone (within 5 cm) as this impairs speech clarity if you speak loudly.
• In case of the headset microphone, by adjusting the gooseneck, locate the microphone with the supplied
windscreen in front of your mouth, and position it 3 – 5 cm away from your mouth for the best sound
reproduction. When the microphone is too close to your mouth or you speak too loud, speech clarity will be
impaired, making it hard for the audience to hear announcements.

Issue
Condition
Solution
No operation of Transmitter
Check the capacity of the
battery
Replace the current battery with
a fresh one of the correct
Alkaline “AA” type.
No RF signal on receiver
Receiver Reception lamps
[either A or B] , mute indicator ,
and RF signal level meter do not
light.
Check the transmitter and
receiver are “Tuned” to the same
channel.
No sound
Receiver Reception lamps
[either A or B] or RF signal level
meter lights.
Confirm the connections of all
sound system or gain.
Sound distorted
VU bar graph on the receiver
shows too high.
Confirm the transmitter gain.
Reduce the gain of the
transmitter if the VU meter shows
over 6dB.
Confirm the receiver XLR mic-
line switch for a correct match to
your Mixer/Amplifier.
AF Signal low level with high
background noise
VU bar graph on the receiver
shows low.
Adjust the transmitter gain so the
VU bar graph shows 0dB with
6dB peaks.
External Head amplifiers not
operating
Receiver Reception lamps
[either A or B] , mute indicator ,
and RF signal level meter do not
light.
Check for shorts in the leads and
ensure the receiver
PHANTOM
PWR

menu.
Receiver LCD contrast poor
Check the LCD contrast.
Enter the receiver
