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

6. CHANNEL NUMBER

SETTING by MANUAL

Step 1. Press the SET key for about 3 seconds until the displayed channel number blinks.

Step 2. Select the desired channel number with the SET key, and once the desired number is

reached, release the SET key. After about 5 seconds, the receiver automatically sets

channel and the blinking number turns to steady light.

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.

7. CHANNEL NUMBER

SETTING by

INFRARED SYNCHRONIZATION

Step 1. Confirm that the receiver is set the channel number and the transmitter is

turned the power on, and open the battery case on the transmitter.

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

the channel number display.

Step 2. After channel scan finishes, the idle channels are displayed in turn.

Step 3. Press the SET key and the SYNC key at the same time, the receiver sets the

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.

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.
