Selecting an Eartip

Selecting an eartip:

No two ears are exactly alike. The eartip that is most comfortable is the best choice, but it must seal well to prevent feedback (whistling) and provide proper protection.

When changing eartips make sure the eartip ﬁts securely on the stem of the device.

moistening may ease insertion.

• When using foam eartips: Roll

down or compress the foam eartip before inserting. Hold the eartip in place for about 5 seconds while foam expands to create a tight seal in the ear canal.

no compression is needed; simply push it into your ear.

Removal

a slow

twisting

motion.

• After removal, place your

device(s) in a protective case.

Batteries

Zinc-Air Batteries

Use commonly-available #10 zinc-air hearing aid batteries. They are easy to ﬁnd in pharmacies, online, and at various retail locations.

• Zinc-air batteries have a long shelf life, but once

the tab is removed, battery life is about 9 days for continuous operation.

• Battery life is about 2 weeks if the devices are turned off after each use.

• Once the tab is removed, zinc-air batteries may self-discharge in about 4 weeks whether used or not.

• The discharge rate varies with temperature and humidity.

• It is sometimes possible to prolong the life of a battery by replacing the tab over the air holes, but results vary.
