Disposal

200 5-08- 13

Dispose of any unusable devices or batteries responsibly and in accordance with any applicable regulations.

Disposing of used batteries with domestic waste is to be avoided!

Batteries / NiCad cells often contain heavy metals such as cadmium(Cd), mercury(Hg) and lead(Pb) that makes them unsuitable for disposal with domestic waste. You may return spent batteries/ accumulators free of charge to recycling centres or anywhere else batteries/accumulators are sold.

By doing so, you contribute to the conservation of our environment!

Antenna Installation:

! Install 2 separate antennas on the antenna sockets on the rear panel.

illustrated in (Figure 1/Figure 2).

Connecting the power supply:

! AC Power Operation: Connect the AC power cable to the AC Input Jack , then

plug the other end into an AC outlet having the correct voltage and rating, (See Figure 2)(ACT-828)

! DC Power Operation: Connect the output end of AC/DC power supply to DC 12V

Input Jack , then plug the power supply unit into an appropriate AC outlet as

shown in (Figure 3). (Caution: Be sure the power supply is connected to an AC outlet with the correct voltage and rating.)

(Figure 3)

(Figure 4)

Audio Output Connection:

Level Switch Setting Position for Unbalanced Output:

! When connecting from receiver's unbalanced output to the “LINE-IN” jack of a mixer

or amplifier or “Electric Guitar”, switch the Level Switch to “LINE” position. Low sensitivity may occur if switch to the wrong level position. When connecting from receiver's unbalanced output to the “MIC IN” jack of a mixer or amplifier; switch the Level Switch to “MIC” position. Louder or quieter volume of microphone may occur if switch to the wrong level position. When using electric guitar, don't use “MIC” position as it may have generated insufficient level.

Connection Method of Unbalanced Output:

! When receiver and mixer/amplifier is under short distance. Or the connectors of

receiver/mixer/amplifier are "PHONE” types. Using audio output cable attached with “PHONE PLUG” type, connect one end from the unbalanced output jack, of the receiver, and the other end to the “LINE-IN” input jack of the mixer/amplifier, as shown in (Figure 1/Figure 2).

! Balanced Output Switch: 2 levels of output gain are available: LINE or MIC

Select the most appropriate output level to interface with your mixer or amplifier. If distortion is experienced, adjust the level control to a lower setting until the desired output is attained.

Balanced Output: Using audio output cables with 3 pin "XLR" type connectors, connect one end to the balanced output socket of the receiver, and the other end to the "MIC IN" input of the mixer or amplifier, as shown in (Figure 1/Figure 2). (The configuration of the 3-pin connector is as shown in (Figure 4))

Electric Guitar Output: Using an XLR to 1/4” Jack type connector cable (use Pins 1 and 2 only) connect to guitar input socket on amplifier. Make sure that the gain level is set at 0dB on both receiver and transmitter.
