Transmitter Setup

Battery Selection and Installation

An alkaline 9-volt battery is recommended. Make certain the transmitter power switch is Off before installing or changing batteries.

When inserting the battery, observe correct polarity as marked inside the battery compartment. The transmitter housings are designed to prevent incorrect installation of the battery; do not force the battery in. Reversed batteries may cause damage to the transmitter.

UniPak® Transmitter Battery Installation

1.Slide off the battery cover as shown in Figure D.

2.Carefully insert a fresh 9V alkaline battery, observing polarity markings.

3.Replace the battery cover (Fig. E).

Handheld Transmitter Battery Installation

1.While holding the upper part of the transmitter body just below the ball-screen, unscrew the lower body cover and slide it downward to expose the battery compartment (Fig. F). Do not attempt to pull the lower body farther down, or to gain access to the electronics.

2.Lift the white “battery keeper” arm until it sticks straight out from the mic body (no higher). Then carefully insert a fresh 9V alkaline battery, observing polarity markings.

3.Screw the body back together. Do not overtighten.

Battery Condition Indicator

The red battery condition indicator (Fig. H/I) should light strongly with a fresh battery. As the battery weakens, the indicator will grow dimmer. When the indicator becomes very dim or goes out, there is little life left in the battery. Replace it at once for continued operation of the transmitter.

All transmitters feature battery-save switches (Fig. D/F). As supplied, the switch is set in the High position for maximum range. Switching to the Low position increases battery life by reducing power. (Note: Effective range decreases when the switch is set in Low position.)

UniPak® Transmitter Input Connection

Connect an audio input device (microphone or guitar cable) to the input connector on the bottom of the transmitter. The cable connector latches automatically when inserted into the transmitter jack. To unlatch and remove the connector, simply pull up on the connector’s knurled metal collar.

A number of Audio-Technica professional microphones and cables are available separately, pre-terminated with a UniPak input connector (see www.audio-technica.com).

Transmitting Antenna

The UniPak transmitter includes a permanently attached flexible antenna. For best results, allow the antenna to hang freely and full length from the bottom of the transmitter. If the received signal is marginal, experiment with different transmitter positions on your body or instrument; or try repositioning the receiver. Do not attempt to remove, replace or change the length of the transmitting antenna.
