BATTERY INSTALLATION
The transmitter is powered by a standard alkaline or lithium 9 Volt battery. It is important that you use ONLY an
ALKALINE or LITHIUM battery for longest life. Standard zinc-carbon batteries marked “heavy-duty” or “long-
lasting” are not adequate. Ni-cad rechargeable batteries will only provide 1.5 hours of operation, or less, and will
run down quite abruptly. Unless it is cold, alkaline batteries provide over 4.5 hours of operation. Lithium batteries
can be used to provide up to 14 hours. Care should be taken not to leave a fully discharged lithium battery in the
transmitter, as swelling of the battery can make it difficult to remove from the compartment. The battery status
circuitry is designed for the voltage drop over the life of alkaline batteries.
To open the battery compartment, press outward on the cover door in the direction of the arrow as shown in the
drawing. Only firm, sliding pressure is needed to open and close the battery door. Swing the door open and take
note of the polarity marked inside showing the location of the positive (+) and negative (-) terminals. You can see the
large and small contact holes inside the battery compartment with the door open.
Insert the battery correctly and close the cover by pressing the door closed and across, reversing the opening
procedure illustrated above. If the battery is inserted incorrectly, the door will not close. Do not force the door
closed.
OPERATING INSTRUCTIONS
1) Install a fresh battery according to the instructions above.
2) Insert the microphone plug into the input jack, aligning the pins; be sure that the connector locks in.
3) Attach the antenna to the SMA connector on the top of the transmitter.
4) Mute the sound system.
5) Turn the transmitter power switch to the “ON” position.
6) Position the microphone in the location you will use in actual operation.
7) While speaking or singing at the same voice level that will actually be used, observe the MODULATION LEDs.
Adjust the AUDIO LEVEL control knob until the LEDs begin to light. Start at a low setting where neither LED
lights as you speak.
