Suggestions for Receiver
Management:
Different types of facilities will use different
approaches for receiver management and earphone
sanitation. Following are some alternatives that other
customers have used successfully:
1.
Regular users purchase their own receiver and
take care of their own batteries and earphone.
2.
Some facilities label the receiver and earphone
with the names of regular users so each person
uses the same receiver and earphone.
3.
Ushers issue receivers to people who request
them. Earphones are sanitized after use. Foam
ear cushions can be replaced or washed with a
mild detergent, rinsed thoroughly and air-
dried. The EAR 022 Surround Earphone can
be sanitized with an alcohol pad.
4.
The receivers are stored in a multiple
compartment storage case with a credit card or
driver's license left as collateral for the
receiver.
5.
Regular users purchase their own earphone or
headphone and bring them to use with
receivers at the facility.
Troubleshooting:
Transmitter “Power” light not on.
1.
Make sure the wall transformer is plugged into
the transmitter and the power switch or any
remote power switch is on..
2.
Make sure the electrical outlet is on.
3.
Make sure the MOD1 is on. The TX3 shuts off
when there is no 95kHz modulation signal.
4.
Make sure the 24VAC power supplies are
working.
No sound through receivers.
1.
If some of the receivers work but others don’t,
check for bad batteries or earphones on the
receivers that aren’t working.
2.
If none of the receivers work, check to see if
the power and 95 kHz carrier cable are
connected to the transmitter and the “Power”
like is ON.
3.
Check to see if the modulator is connected
properly to the sound system. The audio level
lights should be flashing on the modulator.
4.
Make sure the “eye” is not covered up on the
receiver. There must be clear line of sight
between the receiver eye and the transmitter
panel.
Sound through the receivers is weak
and noisy.
1.
Hold a receiver in front of the Infrared Test
LED on the front of the MOD 1 modulator and
listen to the signal. If the signal is weak and
noisy here, check the Input Level switch and
Input Level Control settings. Increase the input
signal level from the sound system by turning
up a mixer control. If the signal sounds okay,
you may need to re-position the transmitter
panels or add additional panels.
Buzzing or humming noise in sound
system.
1.
Check for ground loops or noise on the input
signal. Call your Authorized Dealer or
Williams Sound for help.
