System Operation (continued)

		To change channel automatically
		Press and hold the Set/Scan button for about two seconds. The current
		channel will flash three times quickly; then the system will begin to
		scan for the next open channel. When it finds an open channel, it will
		flash the open channel three times and then set the channel. (If an
		open channel is not found, the automatic scan will return to the original
		channel and flash 5 times.)
		Transmitter On…
		Before turning on the transmitter, use the provided screwdriver to set
		the transmitter channel selector switches (Fig. D on page 2 and Fig. H
		on page 3) to the same number that is displayed on the receiver. Select
		channels 1-8 (channels 9 and 0 are for service use). The transmitter
		may be either on or off when changing channels (frequencies). When
		changing channels with the transmitter on and unmuted, the LED will
		turn red as the adjustment is being made; it will turn green when the
		channel is set.
E		(When changing channels with the transmitter on and muted, the LED
N		will remain red during and after channel adjustment, as long as the
		transmitter is muted; when the transmitter is unmuted, the LED will
		turn green.)
		The transmitters have a soft-touch Power Switch. When the
		transmitter is “on,” the transmitter produces both RF and audio.
		When the transmitter is switched on and in normal operation, the
		receiver’s diversity indicators will display which antenna is active.
		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-T702 Handheld Transmitter
		The 700 Series handheld transmitter trim (volume) control (Fig. H on
		page 3) has factory pre-set audio input levels. Factory setting is full
		clockwise, maximum gain.
		Set the receiver’s AF Level control to its full clockwise position
		(maximum). (Fig. C on page 2).
		While speaking/singing into the microphone at typically loud levels,
		check the AF peak indicator on the receiver. If the AF peak indicator is
		easily 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 trim
		control (Fig. H on page 3). Remove the screwdriver and gently turn the
		trim control counterclockwise until the AF peak indicator 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.

		CAUTION! 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
		ATW-T701 UniPak™ Transmitter
		Trim controls in the UniPak transmitter (Fig. I) will enable you to use
		microphones or instruments with different output levels.
	See illustration figures page 3

1 For MIC: Set MIC (microphone trim) control fully clockwise (maximum) and INST (instrument trim) control fully counter clockwise (low).

For INSTRUMENT: Set INST (instrument trim) control fully clockwise (maximum) and MIC (microphone trim) control fully counterclockwise (low).

2.Set the receiver’s AF Level control to its full clockwise position (maximum). (Fig. C on page 2).

3.Plug the mic or instrument into the transmitter and power up the system.

4.For MIC: Make an initial adjustment of the mixer’s level controls that will allow audio through the system.

For INSTRUMENT: Make an initial adjustment of the instrument amplifier input level control that will allow audio through the system.

5.For MIC: While speaking/singing into the microphone at typically loud levels, check the AF peak indicator on the receiver. If AF peak indicator is easily 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, gently turn the microphone trim control counterclockwise until the AF peak indicator is illuminated only on audio peaks.

For INSTRUMENT: While playing the instrument at typically loud levels, check the AF peak indicator on the receiver. If AF peak indicator is easily 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, gently turn the instrument trim control counterclockwise until the AF peak indicator is illuminated only on audio peaks.

6.For MIC: While again speaking/singing into the microphone at typically loud levels, adjust the mixer’s input trim control so the highest sound pressure level going into the microphone causes no input overload in the mixer, and yet permits the mixer’s channel and output level controls to operate in their “normal” range (not set too high or too low).

For INSTRUMENT: While again playing the instrument at typically loud levels, adjust the receiver’s AF Level control so the highest signal level causes no input overload in the instrument amplifier and yet permits the amplifier’s input level controls to operate in their “normal” range (not set too high or too low).

Note: If the mixer cannot be adjusted to operate in its normal range without distortion, adjust the receiver’s AF Level Control (turn counterclockwise) until the mixer/amplifier is no longer overloaded.

Note: RF power may be set to high or low via the RF power select switch on the side of the UniPak transmitter. (Fig. I.) While the high setting normally provides maximum operating range, the low setting will help extend battery life. The low setting may also be preferred in multi-channel systems, or when operating very close to the receiver, to reduce the possibility of interference or overload.

RF Interference

Please note that wireless frequencies are shared with other radio services. According to the National regulations, “Wireless microphone operations are unprotected from interference from other licensed operations in the band. If any interference is received by any Government or non Government operation, the wireless microphone must cease operation...” If you need assistance with operation or frequency selection, please contact your dealer or Audio-Technica.
