Before the Soundcheck
1. Check the transmitter battery and replace or recharge it if necessary. Use fresh alkaline
batteries only.
2. Adjust the level of the receiver to the amplifier or mixing console.
3. Check the performance area for dropouts. If you find any dropouts, try to eliminate them
by repositioning the antennae or the receiver.
4. The receiving antennas should be placed so that the distance between receiving antennae
and transmitter is at least 3 m. If necessary, use remote antennae (GPA 700).
5. To avoid popping try holding the microphone at a slight angle below the mouth.

Positioning of Transmitters if Interference occurs
Put all transmitters
in their position and switch them on. Switch each transmitter off
one at a time and check the receiver for interference in the corresponding channel. In case of
interference, move the transmitter one at a time to find out which one is causing the
interference. Exchange the transmitters among themselves or change the carrier frequency
until the system is operating without any interference. The interference is possibly eliminated
by changing the squelch.

What to Do against Feedback
Feedback is caused
by your microphone getting too close to a loudspeaker.
We recommend:
• Reduce the volume of the sound system.
• Move away from the loudspeaker.
• Turn the microphone away from the loudspeaker.
• Power supply is interrupted, power supply
unit is not connected to the mains and / or
to the NE 500 receiver
• Connect the power supply unit to
the mains and / or to the NE 500
• Switch on the transmitter
• Make sure that transmitter and
receiver are on the same frequency
• Extend the receiving antennae
• Check the antenna cables
