Operation is subject to the condition that this device does not cause harmful interference. Operation is subject to the following conditions: 1) This device may not cause harmful interference and 2) this device must accept any interference received, including interference which may cause undesired operation. Two antennas feed two completely independent RF sections on the same frequency; automatic logic circuitry continuously compares and selects the superior received signal, providing better sound quality and reducing the possibility of interference and dropouts. [. . . ] Can be connected to an unbalanced aux-level input of a mixer, guitar amp or tape recorder. POWER INPUT JACK: Connect the DC plug from the included in-line AC adapter. CORD HOOK: Loop the small DC cord around the cord hook to keep the DC plug from pulling out accidentally. 5 Transmitter Controls And Functions Battery Selection Two 1. 5V AA alkaline batteries are recommended. 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. 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.

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. 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. Do not force the trimmers beyond their normal 180° range of rotation. Return the screwdriver to its storage clip when not in use. To change channel automatically 1. The Automatic Scan/Set Mode will automatically scan for and set the next open channel. [. . . ] For permanent or temporary installation; mounts to 5/8"-27 threads. ATW-RA1 Rack-mount antenna kit brings antenna inputs to the front of receiver for ease of setup, or when receiver is enclosed in a metal rack. NOTE: Two adapter kits are required when mounting two receivers side-by-side in a single 19" rack space.
