Disposal

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!

Receiver Installation

1. Install two detachable antennas to Antenna Input Connectors 0.
2. Plug DC plug into the DC Input Jack~ and the power cord, into a power outlet.
3. Audio Output Connection: (A) Using audio output cables with “XLR” or “Cannon” type connectors, connect one end to the balanced output jacks~. of the receiver, and the other end to the “MIC IN” input jack of the mixer or amplifier.
   The configuration of the 3-pin connector.

(B) Using audio output cable attached with “6.3mm Phone Jack” type, connect one end from the unbalanced output jack0 9, 13, of the receiver, and the other end to the “LINE-IN” input jack of the mixer or amplifier.
(C) For mixed output, switch Balanced& Unbalanced Mixed Switch 11 to MIX.
(D) Guitar Amplifier Connection: Plug a 6.3 0 both end cable, one end to Unbalanced B 6.3 0 Audio Output Jack of receiver and one end to input socket of electric guitar amplifier. Adjust “Level Switch” of receiver to “+10dB” position.

4. Receiver Rackmount Installation:
   (A) Can be installed into an EIA-standard 1 U Rack and fasten with optional rackmount kit.
   (B) For ideal reception and performance, install the receiver at least 1 meter (3 feet) above the ground and away from EMI / RFI “noise” sources.
   

Receiver Operating Tips

1. Minimize mixer/PA volume and power is off for transmitter before powering on the receiver.
2. Adjust Sensitivity Level Adjuster 5 for ideal receiver sensitivity level. When “NOISE” indicator 4 is lit when transmitters are powered-on or during performance it indicates the receiver is receiving interference signals.
3. Loud noise may bursts when transmitter is powered off, but NOISE indicator is lit indicating receiver is experiencing interfering signals. Adjust Sensitivity Level Adjuster to the left (counter clock) to minimize the interference noise. Change to a new receiver with a different frequency may be required if unable to overcome the interfering noise.
4. Under normal circumstances, the RF LED indicators 2 lights up when a transmitter is turned on near the receiver to indicate the receiver is ready for normal operation. Once sounds enter into the microphone the Audio LED indicators 3 will illuminate according to the strength of sound level. If the LEDs do not illuminate or sound is not present at the output, the system is not functioning properly and must be checked.

Receiver CAUTION

1. Since the installation of the antenna influences the operating efficiency of the receiver, the most important rule is to minimize the distance as much as possible between the receiving antenna and the microphone for the best reception and performance.
2. The output voltage of the external DC power supply should not be below 12V, otherwise it will not work properly. If the voltage is over 15V some components of the receiver will be damaged due to excessive current draw.
3. Use supplied antennas to ensure ideal receiver sensitivity.
4. Use MIPRO external antenna systems for extended reception range.
5. Use an antenna divider system to simplify multiple receiver antennas installation for improved reception quality.
6. For multiple compatible channels operation, use the non-interference frequencies within the same group for best frequency coordination.
