No sound output, RF/AF LED(s) are not glowing | • Make sure the microphone and receiver power |
| switches and receiver are set to the ON position. |
| • Check microphone charge to ensure there is |
| sufficient power. Charge mic if necessary |
• Check receiver’s AC power connection.
• Make sure antennas are firmly connected and extended to an optimal position.
• If necessary, reduce the distance between the microphones and receiver.
• Turn up the receiver’s VOLUME level controls.
• Check for proper connection between receiver and external amplifier/mixer.
• Talk into the microphone and observe the receiver’s RF/AF signal LED’s. If they glow, the problem is elsewhere in the sound system.
