3000 Series Professional UHF Wireless Systems ATW-3110a UniPak™ Transmitter System ATW-3141a Handheld Dynamic Microphone System Installation and Operation
Professional UHF Wireless Systems Installation and Operation This device complies with part 15 of the FCC Rules. Operation is subject to the condition that this device does not cause harmful interference. This device complies with INDUSTRY CANADA R.S.S. 210, en conformité avec IC: RSS-210/CNR210.
Receiver Installation Location For best operation the receiver should be at least 3 ft. (1 m) above the ground and at least 3 ft. away from a wall or metal surface to minimize reflections. The transmitter should be at least 3 ft. from the receiver, as shown in Figure A. Keep antennas away from noise sources such as digital equipment, motors, automobiles and neon lights, as well as away from large metal objects.
Receiver Controls and Functions Front Panel Controls and Functions (Fig. B) 1. POWER SWITCH: Press Power switch in and the receiver readouts will light. 2.
Receiver Controls and Functions (Continued) When the receiver is in the Menu or Edit mode, its audio output is silenced. Once control-setting operations are completed (or Escape is used), normal receiver operation will resume with its audio output restored. While in the Edit mode, if no action is taken for approximately 30 seconds (no buttons pressed), the receiver will “back out” to the Menu mode.
Transmitter Controls And Functions Refer to Figures E, F, G and H on pages 18 and 19 for an overview of transmitter features and controls. PWR.LOC LCD Window The Liquid Crystal Display presents a great deal of setup and operating information clearly and conveniently (See examples in Fig. J). The LCD in the transmitters is designed for greatest contrast and best viewing with the window rotated somewhat away from the viewer (about 30 degrees), not straight-on, for a more convenient holding/viewing position.

Transmitter Setup Battery Selection and Installation Each transmitter uses two 1.5V AA batteries, not included. Alkaline type is recommended. Always replace both batteries. Make certain the transmitter power is Off before replacing batteries. UniPak™ Transmitter Battery Installation 1. Open the battery compartment door by sliding the catch down (Fig. K). (If no batteries are inside, the door will not spring open by itself.) 2.
System Operation Switch on the receiver. Do not switch on the transmitter yet. Selecting/Setting Frequency Selection of the desired operating frequency is made through the function menus. It’s usually best to start by setting the receiver’s frequency, to determine there is no local interference on that frequency. Then, always make certain to set the transmitter to the receiver’s exact frequency.
System Operation (Continued) Transmitter On… Turn on the transmitter by pressing and holding the Power/Mute button (Fig. E/F) for a second or two, until the red power indicator and the LCD window have come on. Set Transmitter Audio Input Level A 4-position audio input gain setting, selected through the function menu, serves to match the audio input level to the transmitter for best modulation with minimum distortion.

Ten Tips to Obtain the Best Results 1. Use only fresh alkaline batteries. Do not use “general purpose” (carbon-zinc) batteries. 6. The receiver and transmitter must be set to the same frequency. 2. Position the receiver so that it has the fewest possible obstructions between it and the normal location of the transmitter. Line-of-sight is best. 7. A receiver cannot receive signals from two transmitters at the same time. 3.
Troubleshooting Guide Receiver is not on (LCD window does not light). • Receiver Power switch is not pressed in. • Small DC power cord from included in-line power supply is not plugged into jack on back of receiver. (Use the cord hook to secure it.) • The in-line power supply is not plugged into AC power outlet. • AC power is not present at the AC outlet. Receiver is on (LCD window lights) • No sound • Alert light is OFF: ✓ “RF”, “AF” and “BATT” legends do not appear in LCD… • Receiver is in the Menu mode.
Troubleshooting’s First Line of Defense: Factory-Default Settings Incorrect settings on the receiver and/or transmitter can make the wireless system’s operation seem poor, or even “dead.” To eliminate the possibility that incorrect function settings are the source of problems, restore both the receiver and the transmitter to their factory-default settings. RECEIVER – To return all receiver functions to their original factory-default settings: 1. First, turn the receiver off. 2.
