Cellular Phone and Hearing Instrument Compatibility
Hearing instrument performance with cellular phones may vary based on the indi-
vidual hearing system or the cell phone being used. If your hearing system and cell
phone are not compatible you may experience a buzzing or clicking noise while using
the two in conjunction. If this is the case with your current hearing system and cell
phone, consult with your hearing healthcare professional to see if there are options to
improve the sound quality.
Measures you can take to prevent this situation:
•
When purchasing a hearing system, be sure to test it with your existing phone to
determine compatibility.
•
When shopping for a new cell phone, be sure to test it with your hearing system
before purchasing.
For additional guidance, please, consult your cell phone provider.
Removing/Inserting the Battery
Open the battery door by putting your fingernail under the nail
grip and pulling gently until the battery door is completely open.
Remove the used battery from the battery compartment.
Tip
: Hold the instrument over a table or a soft surface in case
the battery falls out.
Remove the film from a new battery and place the new battery
into the battery compartment, matching the plus (+) sign on flat
side of the battery to the plus sign in the battery compartment.
A magnifying glass and good lighting may be helpful in seeing these small markings.
The correct battery size for your CIC instruments is a 10A.
Close the battery compartment tightly but do not use force - it should close very easily.
Your hearing system should now be on.
