WHT-15 Handheld Microphone Transmitter

1.Unscrew the BATTERY COMPARTMENT COVER (12) and remove, exposing the BATTERY HOLDER (13). Insert a fresh 9V ALKALINE BATTERY (14), observing the correct polarity as marked, and screw the cover back on to the microphone. Make sure the cover is screwed on completely. A fresh alkaline battery can last up to 15 hours in use, but in order to ensure optimum performance, it is recommended that you replace the battery after every 10 hours of use.

2.Turn on the WHT-15 by sliding the OFF/STANDBY/ON SWITCH (15) to the STAND- BY position (transmitter on, audio muted) or the ON position (transmitter and audio both on). The BATTERY INDICATOR LED (16) will give a single quick flash, indicating usable battery strength. In the case of a dead or low battery, the LED will either not go on at all or will stay on continuously, indicating that the battery should be replaced with a fresh one. To preserve battery life, turn the transmitter off when not in use.

3.The microphone is now ready to use. The TX LED INDICATOR (5) on the 401 receiver should now be lit, indicating a received signal from the transmitter. When ready to speak, slide the transmitter switch to the ON position. Adjust the volume of the receiver as per the Audio Output Microphone Connection section of the above 401 receiver instructions. The AF LEVEL LED DISPLAY (9) on the 401 receiver will light up to 5 LEDs (4 green and 1 red) for all

input signals. Occasional flickering on and off during use of the top red LED indicator in this display is normal, however if the red LED stays on continuously, it means the signal is too loud and there is the possibility of overload distortion. If this occurs, back off from the microphone until the red LED indicator only flickers on peaks.

[Note: Observe care in selecting P.A. volume, transmitter location and speaker placement so that acoustic feedback (howling or screeching) will be avoided.]

[Note: Microphone elements can easily be destroyed by the buildup of salts and minerals from perspiration and saliva. It is good practice to put a windscreen on the mic element at all times to protect it.]
