Hearing
Aid Compatibility Production Solution
Manufacturing facilities can take advantage of the
production solution for HAC testing. A pickup coil mounted in the
Acoustic Fixture provides a Go/No Go quick check (no measurements
taken). This will verify the magnetic coil in the handset is functioning
on the production floor.
Non Magnetic Handset Fixture (Optional)
The HAC System can be supplied with a non-magnetic handset fixture to
help in making measurements. As you see in the photo below it has two knobs on left and right that are used to hold the handset firmly without
damaging it. There are also two adjustable support posts under the handset to hold the handset the correct vertical
attitude. The handset is placed such that the receiver is level with the two square sections that are marked with blue lines. The support posts are adjusted so that the handset
receiver is supported securely and is level in all directions. The blue lines are on the fixture to help the operator orient the Tibets coils at the 0 degree, 90 degree and 270 degree positions are required in the specification.
