TIPS AND TROUBLESHOOTING

Tips for getting the best performance

• Maintain a line of sight between the transmitter and receiver antennas.
• Keep the receiver and antennas away from large metal objects.
• Avoid placing the receiver near computers or other RF generating equipment.
• Point the receiver antennas straight up.
• Avoid placing the receiver in the bottom of an equipment rack unless the antennas are remotely located.

Troubleshooting

Some common problems and their solutions are identified in the table below. If you are unable to solve a problem, contact your dealer.

Problem

|

Solution

---|---
No sound; RF light(S) not glowing.| • Make sure the transmitter POWER switch is ON and the receiver is plugged into a power source.
• Check battery.
• Check receiver squelch setting.
• Check receiver antenna connection(s).
• Make sure antennas are in line of sight of transmitter.
No sound; RF lights glowing.| • Turn up receiver audio VOLUME control.
• Check for proper connection between receiver and audio mixer unit.
Received signal is noisy or contains extraneous sounds with the transmitter on.| • Check battery.
• Remove local sources of RF interference.
• If using a guitar or other instrument, check connections. Two transmitters may be operating on the same frequency. Locate and tum one-off.
• Signal may be too weak. Reposition antennas. If possible, move them closer to transmitter.
Noise from receiver with transmitter off.| • Adjust receiver squelch control.
• Remove local sources or RF interference.
• Reposition receiver or antennas.
Momentary loss of sound as transmitter is moved around performing area.| • Reposition receiver and perform another “walk through” lest and observe the RF indicators. If audio dropouts persist, mark these dead spots in the performing area and avoid them during the performance.
