Safety Symbol and Message Conventions
Safety symbols and messages described below are used in this manual to prevent bodily injury and property
damage which could result from mishandling. Before operating your product, read this manual first and
understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.
WARNING Indicates a potentially hazardous situation
which, if mishandled, could result in death or
serious personal injury.
When Installing the Receiver
• Do not expose the unit to rain or an environment where it may be splashed by water or other liquids, as
doing so may result in fire or electric shock.
• Use the unit only with the voltage specified on the unit. Using a voltage higher than that which is specified
may result in fire or electric shock.
• Do not cut, kink, otherwise damage nor modify the power supply cord. In addition, avoid using the power
cord in close proximity to heaters, and never place heavy objects -- including the unit itself -- on the power
cord, as doing so may result in fire or electric shock.
• Avoid installing or mounting the unit in unstable locations, such as on a rickety table or a slanted surface.
Doing so may result in the unit falling down and causing personal injury and/or property damage.
• To prevent lightning strikes, install the unit at least five meters away from a lightning rod, and yet within the
protective range (angle of 45°) of the lightning conductor. Lightning strikes may cause a fire, electric shock
or personal injury.
• Since the unit is designed for in-door use, do not install it outdoors. If installed outdoors, the aging of parts
causes the unit to fall off, resulting in personal injury. Also, when it gets wet with rain, there is a danger of
electric shock.
When the Receiver is in Use
• Should the following irregularity be found during use, immediately switch off the power, disconnect the power
supply plug from the AC outlet and contact your nearest TOA dealer. Make no further attempt to operate the
unit in this condition as this may cause fire or electric shock.
· If you detect smoke or a strange smell coming from the unit.
· If water or any metallic object gets into the unit
· If the unit falls, or the unit case breaks
· If the power supply cord is damaged (exposure of the core, disconnection, etc.)
· If it is malfunctioning (no tone sounds.)
• Do not place cups, bowls, or other containers of liquid or metallic objects on top of the unit. If they
accidentally spill into the unit, this may cause a fire or electric shock.
• Do not touch the unit's antennas during thunder and lightning, as this may result in electric shock.
When the Microphone or the Transmitter is in Use
• To prevent the electromagnetic wave from badly influencing medical equipment, make sure to switch
off the unit's power when placing it in close proximity to the medical equipment.

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.
14. TROUBLESHOOTING
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 is switched on via the RX
SETTINGS menu.
Receiver LCD contrast poor Check the LCD contrast. Enter the receiver RX
SETTINGS menu, select LCD
and press then rotate the “Jog-
Wheel” to adjust the contrast.

19
Poor range or sound dropouts Receiver Reception lamps [A
and B] are flicking or RF signal
level meter turn light off..
The system must be set up
within recommended range.
The transmitter must be used in
line of sight from the receiver.
Check the channel scan, confirm
nearby source of interference,
and change the receiver and the
transmitter to a different channel.
Check the mute level setting. For
normal range we recommend a
mute setting of 4-6.
Confirm the battery indication,
and replace the transmitter
battery.
