Suggestions For Receiver Management

Different types of facilities use varying approaches to receiver management and earphone sanitation. Following are some options

that customers have used successfully:

1. Regular users purchase or are given their own receiver and also take care of their own batteries and earphones.

2. The facility labels a receiver and earphone for each regular user. The facility maintains the units.

3. Ushers issue receivers to people who request them.

4. 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.

5. The receivers can be stored in a multiple compartment storage case with a credit card or driver’s license left as collateral

for the receiver.

6. Regular users purchase their own earphone or headphone and bring them to use with receivers at the facility.
