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

Tip Continuous or each depression of the SET key permits the display to cycle through the
channel numbers.
On the receiver side, when the dot LED by the channel number LED is blinking at
selecting channel number, this means that the channel has already been occupied.
Note Make sure that the transmitter is identical to the receiver in the channel number.
Should the microphone's setting differ from that of the receiver, the receiver does not receive the
radio signal from the transmitter.
On the transmitter side, the power switch turns on, the channel
number display turns on the light for about 30 seconds, and
then this display turns off the light. When SET key presses in
this condition, this display turns on the light for about 30
seconds.

Step 2. Bring the IR port in the transmitter within 20cm of IR port on the receiver.
Step 3. Press the SYNC key on the receiver for about 3 seconds. When the
channel data be transmitted successfully from the IR port on the receiver,
the displayed channel number flashes.
Step 4. When the channel number are synchronized
successfully between the receiver and the
transmitter, the displayed channel number in
the transmitter blinks for about 3 seconds,
Note On the transmitter side, even if the channel
number display turns off the light, the display
turns on again when IR synchronization
succeeds.
8. CHANNEL
SCAN
Step 1. Press the SET key and the SYNC key at the same time for about 3 seconds.
Channel scan begins, and an idle channel number is indicated blinking on

idle channel automatically.
Note Before starting the channel scan, turn off all transmitters and any other
equipment that could cause the interference during the performance so it will be detected during the
channel scan.
If there are no idle channels, the channel number is displayed blinking as a “-“.
And then the channel before starting the channel scan is set again.
Multiple System Setup
Set up each system one at a time, confirm each system is assigned a different
channel, and leave the transmitter powered on. Otherwise, the channel scan from the other receiver will
not detect as the occupied channel.

BATTERY ALARM INDICATON
• When the battery capacity in the corresponding transmitter becomes low, the dot LED of the numerical LED
on the receiver and the transmitter blinks. Replace the transmitter battery.
11
10.
OPERATIONAL HINTS
• The transmitter's service distance is 3 – 100 m. 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.
• The proper operation of your wireless system may be interfered with by other system operating on the same
frequency. In such cases, change the operating frequency of your system.
• 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.
