Step 1. Switch off the power. Rotate the microphone grip
counterclockwise to remove it.
Step 2. Using the screwdriver housed in the microphone
body, set the Channel selector switch pointer to
the desired channel number.
Step 3. Replace the microphone grip.
Note
Make sure that the wireless microphone is identical to the
wireless tuner in the channel number.
Should the microphone's setting differ from that of the
tuner, the tuner does not receive the microphone signal.

8. PAD SWITCH
The input sensitivity can be decreased by 0 dB, –6 dB or –12 dB with the PAD switch.
Select the appropriate level so that the output sound is not distorted when the volume
control knob of the tuner is set at the 2 o'clock position.
If a loud voice distorts the output sound, decrease the sensitivity by shifting the PAD switch
to the –6 dB or –12 dB position.
Note: The PAD switch is factory-preset to 0 dB.
The table at right shows the relationship
between the PAD switch positions and the
maximum input levels.
9. OPERATION
Step 1. Confirm that the wireless microphone and the wireless tuner are identical in the channel number.
If not identical, turn off the power ON/OFF switch, then set the channel number to the same channel
number as the tuner.
Step 2. Hold down the power switch for one second or more to turn on the power.
Then, confirm the green LED of the Power/Battery lamps will light.
Step 3. Hold down the power switch for one second or more to turn off the power after use.
10. OPERATIONAL HINTS
• The microphone's service distance is 3 – 120 m. When the microphone 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.
• 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. (As to dealing with the
interference, refer to the operating instructions of the wireless tuner.)
• Should you have any questions regarding the use or availability of TOA wireless products, please contact
your local TOA dealer.
• If the output sound is distorted at the large volume level, use the microphone by shifting the PAD (input
sensitivity reduction) switch to the –6 dB or –12 dB position to decrease the sensitivity.
• Attach the supplied rolling stopper as needed, preventing the microphone
from rolling and dropping onto the floor.
