Hearing Aid Anatomy
Check that the battery is working
The hearing aids will make a feedback noise that sounds like whistling when they are not in the ear. Hearing this sound is the best way to tell if the battery is working. A great way to test this is to remove the hearing aid from the ear and give it a very gentle squeeze bringing the ear mould close to the microphone on the device.

Fitting the hearing aid
To fit the hearing aid pull the Helix and the Anthelix away from the Tragus, enlarging the Concha area.
Guild the mould into the ear canel.
The top of the mould should sit in the Fossa Triangularis, not on top.
The Antitragus, Intertragal notch, Tragus and Fossa Triangularis should hold the mould in place.
If you hear whistling feedback, it may need to be reinserted.

Battery Replacement
Ezra's hearing aids are running on small size 13 button batteries. Each battery lasts approximately 1 week. Ezra will usually tell you if his hearing aids are not working, however not always. If you notice Ezra's hearing aids flashing, it means his batteries need replacing. Otherwise if Ezra is not being attentive, having trouble understanding or following instructions in might be good to ask him if they are working. Even then he may say he is fine. The other way of checking is taking them out of his ears and doing the feedback test. We recycle our batteries, so please feel free to pop them in a zip lock bag in his kit and we'll collect them through the year.
Each hearing aid has a different procedure to change the battery. However its as simple as using the little door hook, prying open the door and replacing the battery.

Cleaning & Blockages
When there is a blockage, whether it be from ear wax or discharge, the hearing aid is unable to transmit sound from the receiver into the ear. Ezra may tell you that he cannot hear or that its 'not working', if he doesn't please watch for signs that he is not paying attention, such as no responding, or doing a task correctly. It's always good to do the feedback test even if Ezra says it's not working. If the blockage is deep in the hard plastic hook it's best to remove the hearing aid from the ear for the day and we will get Hearing Australia to replace the hook. If the blockage is in the soft tubing or the mould it's a lot easier to remove yourself, and will only take a few minutes.

Keeping Them Dry
The Dry Cup.
Unfortunately Ezra's hearing aids are not water resistant and need to stay dry. (Wearing them in light to medium rain is ok, and fine if he is wearing a hooded raincoat.)
If they do end up in water it's best to work fast to get them into the dry cup.
- Remove the battery, and tube with mould attached.
- Place a dry capsule into the bottom of the dry cup and place the hearing aid into the dry cup basket.
- Secure for 8 hours or overnight.

Roger microphone
Roger
The Roger microphone connects directly to Ezra's left hearing aid and has a range of about 20m if there are no walls or obstacles in the way. On full charge its about 11 hours use.
