1. This device may not cause interference.
2. This device must accept any interference, including interference that may cause undesired operation of the device. This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment.

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. Antenna Connection: Connect an antenna to each of the antenna connectors 9 on the rear panel. Fig. 2. Antenna connectors provide an 8-volt DC bias to work with MIPRO antenna boosters. If the antenna cable is longer than 10 meters, it is advisable to  install an antenna booster to ensure optimal reception.
2. Power Connection: Connect the power supply to the receiver DC input 10 and plug it into an AC power source. Fig. 2.
3. Audio Output Connection:
   (A) When connecting the audio output to the MIC IN jack of the mixer or amplifier, switch output level switch 13 to 0 dB. When connecting to LINE IN jack, set output level switch to +16 dB when using balanced XLR connector or set output level switch to  +10 dB when using unbalanced (6.3 Ø ) connector. When connecting to an amplifier with non-standard gain, set output level switch to -6 dB when there is distortion at the maximum output level.
   (B) Output for electric guitar/bass: Use a 6.3 @ phone cable. One end to receiver’s unbalanced output jack and the other end to guitar/bass amplifier’s input jack.
   Switch the output level to the “+10 dB” position.
   (C) Use an XLR cable to connect the receiver audio output jacks 11 15 17 to a mixer or an amplifier’s MIC IN jack.
   (D) Use a PHONE cable to connect the unbalanced phone jacks 12 16 18 to a mixer or an amplifier’s LINE IN jack.
   (E) To mix the multiple channel outputs, connect to the mixed output jacks 11 or 12 and switch the output switch 14 to the MIX position. Fig. 3
   (F) See Fig. 4 for a 3-pin XLR connector wiring diagram.

Receiver Operation

1. Before turning on the receiver, ensure all transmitters are powered off and the mixer’s volume control is set to a minimized setting. When the receiver is turned on and the LED screen glows, it is working normally.
2. RF meter level 27 glows when a transmitter is powered on. Once the audio signal is received from the transmitter, the AF level meter glows in accord with signal strength. The system is abnormal if the RF indicator or AF meter does not glow, then  adjustment or repair might be required.
3. (For ACT-311/ACT-312 only) The microphone volume is adjusted at the amplifier or mixer. No adjustment is needed at the receiver.

Rackmount Installation for Receivers

1. Single half-rack or single full-rack receiver: Install the optional rack mount kit and fasten with screws on both sides. Fig. 5

2. Receiver Rack-Mount Kits (optional). Fig. 6
   

3. Fasten the receivers on an EIA standard 19-inch rack case. Fig. 7

4. For ideal reception range, install the receiver at least 1 meter above the ground and away from EMI / RFI “noise” sources. Besides, place the transmitter at least 1 meter away from the receiving antenna, as shown in Fig. 8.
   

5. Proper install of antennas affects the operating efficiency of the receiver.
   The main principle is to minimize the distance between the receiving antenna and transmitter for best reception quality.

6. Use MIPRO supplied antennas to ensure proper receiver sensitivity.

7. The antenna connector provides an 8V DC bias output. Short circuits should be avoided.

8. Install MIPRO directional antennas and boosters if extended reception distance is required.

9. Use the antenna distributor in the multiple channel wireless systems to simplify the antenna installation and improve receiving efficiency.

10. For multiple wireless systems operations, it is recommended to select MIPRO’s factory preset interference-free channels within the same group to ensure optimum performance.
