SOLUTION
n Check the power cord on the Transmitter and make sure it is
powered on.
n Make sure both the transmitter and the receiver are set to the
same frequency.
n Make sure the earpiece is plugged into the receiver.
n Make sure receiver is on and the battery is good.
n Make sure both antennas are correctly attached.
n Listen to the headphone monitor on the transmitter to check
audio feed.
n Make sure all antennas are fully inserted and secured onto
jacks.
n Try to maintain line-of-sight between transmitter and receiver.
n Try the other frequency in case interference is limiting the
range.
n Check for television channel interference.
n Make sure the PA715 antenna is not remote mounted.
n Make sure no other transmitters are operating on your
frequency.
n Make sure transmitter input level is 0 dB ±3 dB for optimum
performance.
n Listen to the headphone monitor on the transmitter to check
audio feed.
n Try and maintain a minimum of 10 ft. between transmitter an-
tennas and receiver when using multiple transmitters.
n Make sure transmitter input level is 0 dB ±3 dB for optimum
performance.
n Switch the transmitter pad to –10 dBV position if the input is
too low.
