Phonak Nathos Troubleshooting And Maintenance

HOW IT WORKS…
Sound comes in via the microphones, is amplied by the
hearing aid (powered by the battery) and travels through the
hook, tubing and mould into the person’s ear. The hearing aid is
ON when a battery is in place and the battery compartment is
closed and is OFF when the compartment is open (older aids
have a switch: 0 = off and M = on).
IS THE HEARING AID WORKING?
Turn the hearing aid on and cup it between your hands. If your
hearing is OK, you should hear it whistle.
Newer aids usually play a little tune a few seconds after starting
– turn the aid on and hold it near your ear (but not too close!) –
if you hear the tune, the aid is probably working.
