Transmitter operating in the UHF frequency range. The WTU-2 combines

frequency agility and ease of use . The transmitter operates within a 28 MHz

wide segment in 25 kHz steps.

The RF coverage range of the WTU-2 beltpack communicating to a receiver

may be up to 100 meters (328 ft).

The high quality audio circuitry and advanced Radio Frequency (RF) signal

processing offer broadcast quality signal-to-noise ratio and audio clarity.

System features include:

• Durable Painted Metal Case.

• TB-4M Audio Connector.

• Permanent Flash Memory for frequency/setting storage.

• On-Loc prevents accidental power off (when set).

• LCD Display for ease of viewing.

• Flexible quarter wave screw-on Antenna.

Quick set-up:

1. With the Power Switch on the transmitter OFF, install fresh batteries into

the transmitter.

mixer/amplifier or other device during set-up adjustments.

Place the transmitter Power Switch to the ON position.

3. The Battery light near the Off/On switch will flash once and then go off.

If the light does not flash, a bad battery is the most likely cause.

The display will also come on briefly displaying the current frequency

group and channel and the battery level. Note: Anytime Power is

removed and turned back on, the GP/CH/Bat screen will be displayed.
