Helping People Hear
Step 5:
Locate the Tuning Coil. (See figure on previous page). Each tuning coil is a
small, square, shiny metal can with a screwdriver slot in a tuning slug in the top
center. The Tuning Slug is usually black or gray.
Step 6:
With the earphone or headphone supplied with the receiver plugged into the Ear
Jack, turn the volume control to a comfortable level, and listen for the transmitted
signal.
Step 7:
Gently put the tip of the tuning wrench into the slot in the tuning slug. Be careful
not to push hard on the slug so as not to damage the threads in the coil, and do
not screw it down more than 3 turns into the coil.
Step 8:
Turn the tuning slug in a counter-clockwise direction about two turns. Then,
slowly turn the tuning slug in the clockwise direction until the signal is heard.
There may be two signal points heard. The one which is received first is a false
response. Be sure to continue tuning slightly further to the correct point, which
will be much louder. Tune back and forth to find the center of the point of best
response to the program being heard.
Step 9:
Mark down the date, and if a new frequency has been chosen, mark it down
inside the receiver case for future reference.

ANAGEMENT
Different types of facilities will use different approaches for receiver management and
earphone sanitation. Below are some options that customers have used successfully.
þ
Regular users purchase their own receiver and take care of their own batteries and
earphone.
þ
Some facilities label the receiver and earphone with the names of regular users so each
person uses the same receiver and earphone.
þ
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.
þ
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.
þ
Regular users purchase their own earphone or headphone and bring them to use with
receivers at the facility.
