When It Isn't Working

If your wireless system does not appear to be working, the suggestions below will allow you to determine if the wireless equipment is really bad or if there is some other problem. If the system is basically working but there are other problems such as noisy audio or poor range, see the links at the bottom of this page for suggestions on solving these types of difficulties.

  • Make certain that the transmitter battery is in good condition.

  • Make certain that the transmitter control switch is all the way to the "on" position and not still in the "standby" position.

  • Double-check that the wireless transmitter and receiver are on the same frequency. It is easy to accidentally mix up transmitters when more than one system of the same type are in use.

  • Turn on the receiver and make certain that its power indicator is illuminated. Also make certain that the antennas are installed and not touching each other or another object.

  • Turn the transmitter on and bring it to a position about 10 feet (3 m) from the receiver antennas. Observe the receiver "RF," "Tuner" or "RF Level" indicator and verify that it is illuminated.

  • If the receiver RF indicator is not on, try replacing the transmitter battery with a brand new, fresh alkaline battery. If the receiver RF indicator still does not illuminate, the system is most likely defective and should be serviced.

  • If you have another transmitter on the same frequency, try these tests again with the receiver.

  • If the RF indicator is on, try speaking loudly into the microphone while observing the "AF," "AF Peak" or "AF Level" indicator on the receiver.

  • Make certain that the receiver AF level control is set at maximum.

  • If the AF indicator still does not illuminate, and the transmitter is a body-pack unit with a plug-in microphone, make certain that the microphone connectors are undamaged and secure.

  • If the AF indicator still does not illuminate and the transmitter is a body-pack unit, the microphone could be defective. If a spare mic is available, substitute it for the original microphone and again speak loudly while observing the AF indicator.

  • If the transmitter is a handheld unit or there is still no audio indication with the test microphone connected, the system is most likely defective and should be serviced.

  • If the AF indicator does illuminate when speaking into the microphone, but there is no sound in the audio system, check the receiver audio with headphones (if the receiver has a headphone output).

  • If the headphone audio is working, or the audio cannot be tested with a headphone, try turning up the mixer or amplifier input control.

  • If there is still no audio in the system and your wireless is plugged into a mic-level input, try replacing the wireless with a wired microphone. If the wired microphone also does not work, the problem is not in the wireless system.

  • If the wired microphone does work, reconnect the wireless and retest.

  • If there is still no system audio, the wireless system is probably defective and should be serviced.

Other suggestions:
  • For body-pack systems: If the audio is intermittent or noisy when the wearer moves, the problem might be a bad microphone cable. Try a spare microphone or a working microphone from another Audio-Technica wireless system.

  • If no spare microphone is available, try carefully and gently flexing the microphone cable where it enters the microphone capsule and at the connector. If the audio cuts in and out, or is noisy when the cable is flexed, the microphone cable probably is bad.

  • Bad batteries are a common cause of wireless problems. Always make certain to have fresh, new alkaline batteries on hand, and always check the transmitter battery first if there are problems with a system.

  • Ensure that the transmitter battery is secure and making good contact.

  • If the receiver audio is noisy, the problem might be interference. See Quick Tips - Avoiding Interference and Resolving Interference Problems for additional suggestions. If the problem is poor range, it could still be an interference problem. For other suggestions on improving range, see Quick Tips - Maximizing Range and Maximizing Range.
