UniPakTM Transmitter Battery Installation 1. Open the transmitter door by pressing gently on the side-cover indentations and pulling back the hinged cover shown in Fig. Lift the battery-keeper arm, and carefully insert two fresh 1. 5V AA alkaline batteries, observing correct polarity as marked inside the battery compartment. Handheld Transmitter Battery Installation 1. While holding the upper part of the transmitter body by the translucant ring below the ball-screen, unscrew the lower body cover, slide it downward, and remove it to expose the battery compartment. Observe correct polarity as marked inside the battery compartment and carefully insert two fresh 1. 5V AA alkaline batteries. Insert the first battery and slide it down. Then insert the second battery into the space remaining. Make certain the batteries are fully seated in the battery compartment. Slide the lower body cover back up the body, then screw the housing together.

Setting Levels Correct adjustment of transmitter audio input, receiver audio output, and mixer/amplifier input and output levels is important for optimum system performance. ATW-T220 Handheld Transmitter The 2000 Series handheld transmitter has factory pre-set audio input levels. Factory setting is full clockwise, maximum gain. While speaking/singing into the microphone at typically loud levels, check the AF meter levels on the receiver. If all five AF meter bars are consistently illuminated and distortion is heard through the system, it may be necessary to adjust the transmitter audio input level. To adjust the transmitter audio input level, unscrew the lower body cover and slide it downwards, exposing the screwdriver and level trim control (Fig I). Remove the screwdriver and gently turn the level trim control counterclockwise until the topmost receiver AF level meter bar is illuminated only on audio peaks. Return the screwdriver to its clip and close and secure the lower body. No further transmitter gain adjustments should be needed, as long as the acoustic input does not change significantly. The small trimmer controls are delicate; use only the supplied screwdriver. [. . . ] The transmitter and the receiver should be as close together as conveniently possible, but no closer than three feet (1 m). The receiver antennas should be in the open and away from any metal. If mounted in a rack, have the unit on top, or use an ATW-RA1 kit to front-mount the antennas. The transmitter and receiver must be set to the same channel number. [. . . ]
