6. BATTERY INSERTION

Step 1. Hold the microphone body and rotate the microphone

grip counterclockwise to remove it.

Step 2. Insert the battery 6LR61 (Alkaline 9 V) according to

the instructions attached to the inside of the battery
compartment. Pay attention to the correct polarity
when inserting the battery.

Step 3. Replace the microphone grip by sliding and rotating it

clockwise.

Battery replacement

• A brand-new battery will provide the power enough to operate the unit

continuously for 10 hours.

• As long as the battery has sufficient power for the microphone to function

properly, the orange LED will light. When the orange LED starts to fade and
then flash, replace it with a new one.

7. OPERATION

Step 1. Make sure that the receiver and the wireless microphone are of the same bank and channel (frequency).

Step 2. If they are not identical in bank channel, you have to adjust the bank and channel switches.

Step 3. Place the microphone ON/OFF switch in the ON position.

The orange LED indicates the circuit is active. Moving the knob strongly beyond the ON position locks
the switch in place.

Step 4. Make sure to shift the ON/OFF switch back to the OFF position after using the WM-4200 wireless microphone.

To release the switch from lock, move the knob strongly toward the OFF position.

8. OPERATIONAL HINTS

• The microphone's service distance is 3 – 150 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. It is recommended that the Scan
function (of the WT-4800) be used to avoid the frequency interference, which always searches and shows
idle frequencies.

• Should you have any questions regarding the use or availability of TOA wireless products, please contact

your local TOA dealer.

9. BANK/CHANNEL NUMBER SETTING

Step 1. Switch off the power. Rotate the microphone grip

counterclockwise to remove it.

Step 2. Using the supplied screwdriver, set the Bank setting

switch pointer to the desired bank number.

Step 3. Using the supplied screwdriver, set the Channel setting

switch pointer to the desired channel number.

Step 4. Replace the microphone grip.

Note: Make sure that the wireless microphone is identical to the

wireless tuner in both the bank and channel numbers.
Should the microphone's setting differ from that of the
tuner, the tuner does not receive the microphone signal.
