Operating instructions

Introduction

We understand that hearing loss affects one’s quality of life. That is why we are dedicated to building the highest quality hearing aids. Your new hearing aids will soon be indispensable to you and will bring new pleasure and enjoyment to your life.

A period of adjustment may be needed to become accustomed to your new hearing aids and the renewed world of sounds you will experience. The adjustment time varies for each individual and may be from as little as a couple of weeks to as long as several months. Allow yourself time to become familiar with those sounds you have not heard for a long time.

Before operating your hearing aids, please read these operating instructions thoroughly.

Your HD 350

hearing aid

Your HD 350 hearing aids should fit comfortably and easily over the top of your ears.

l Step 1: Place the hearing aid over the top of your ear.

l Step 2: With your index finger, hold the sound

tube where it attaches to the ear dome and gently push the dome into your ear canal until it is just inside your ear canal.

l Step 3: Place the retention guard of the sound

tube into the bowl of your concha.

Be sure to open the battery door after removing the aids from your ears, as this will turn the aids off and conserve battery power.

Proper

placement

on ear

If you are wearing hearing aids on both ears, it is important to use the correct device in each ear. The sound tubes are marked with «red» lettering for the Right ear and «blue» lettering for the Left ear. To turn your hearing aid «on», you simply need to close the battery door after inserting a battery.

There are two ways to turn your hearing aid «off»:

1. Grasp the notch on the battery door and pull it until one click is felt. Your aid is now «off».

2. You may choose to open the battery door completely, which will also turn off the hearing aid.

Turning the

hearing aid

on and off

In fact, when the hearing aid is not in use, it is recommended that you open the battery door and remove the battery. This helps to prevent excessive battery drain and allows for proper ventilation of the hearing aid.

The HD 350 is equipped with a low battery detection system, which continuously monitors battery life.

When the battery becomes low, the low battery warning sequence consisting of 3 double beeps is initiated. After the warning beeps are complete, normal operation resumes.

The low battery warning sequence will repeat every 10 minutes until the battery becomes critically low. At that time, the end of the battery life warning sequence consisting of 6 double beeps is triggered. The device is then muted and put into low power sleep mode.

Battery

information

Battery replacement will then be required.

The life of your hearing aids’ batteries will vary depending on length of daily use and listening environments. When the hearing aid batteries go dead, remove them immediately and replace them with new batteries. Batteries may be purchased from the

HearingDirect.com website.

Important: Always discard used batteries in accordance with your local disposal regulations. Small batteries can be harmful if swallowed. Keep batteries out of the reach of pets and small children. In case of ingestion, contact your doctor immediately.

Follow these steps.

l Step 1: Lift the notch at the edge of the compartment and swing open the door. Do not force it. Remove the battery.

l Step 2: Remove the tab on the 10A

battery, slide in the battery with the «+» side up, matching it to the «+» on the battery compartment door.

l Step 3: Swing the door into the closed

position. The compartment should close easily. Do not force it. If resistance is noted, check that the battery is inserted correctly.

Replacing

your hearing

aid battery

The following instructions will assist in extending the life of your hearing aids.

You should inspect your hearing aids daily and clean them periodically to control wax build-up. To clean, very gently wipe the surface with a soft, dry cloth or moist cleaning wipes made especially for hearing aids. Do not allow water or liquid to enter any openings on the aids. The sound tube delivers the amplified sound from the hearing aid into the ear. It is important that these components fit properly in your ear. The materials used in your hearing aids are of the highest quality available, and the likelihood of an allergic reaction is low. Please don’t attempt to modify the shape or length of the sound tube yourself. The tube and dome should be cleaned regularly according to the instructions on the following pages.

Cleaning your

hearing aid

Cleaning the

exterior of

the aid

The wearing of a hearing aid may accelerate the accumulation of ear wax. This can easily be removed by your doctor. You should not use cotton swabs to clean your ears, due to the risk of pushing the wax deeper into the ear canal.

Remove the sound tube from the hearing aid by gently twisting the tube 90° and pulling it straight off, away from the main aid.

To clean the

sound tube

and ear dome

Use a damp cloth to clean the exterior of the sound tube and dome. Use the cleaning rod (provided in storage case) to clean the sound tube and dome. Lightly push the cleaning rod through the sound tube, inserting it in the opening where the tube attaches to the body of the aid and push out through the dome.

Do not rinse or submerge these parts in water, as there is a risk of damage if a water drop becomes trapped in the sound tube. If this should occur, it will prevent sound from coming through the tube and may be harmful to the hearing aid’s electronics.

Re-attach the sound tube onto the body of the aid by holding the sound tube in one hand and the hearing aid in the other hand. Line up the sound tube and the connecting end of the aid, push the sound tube straight onto the aid body. There is no need to rotate the sound tube when re-attaching.

The sound tube and the dome may need to be changed if the sound tube becomes stiff, brittle, kinked or damaged. When you change the domes, make sure they are securely fastened to the sound tube before inserting them in your ear. Failure to change the dome in accordance with the instructions could result in injury.

Hearing aids are exposed to moisture in the form of humidity and perspiration while being worn. The daily use of a dehumidifying system or drying kit is recommended. These accessories may be purchased from the HearingDirect.com website.

Your HD 350 hearing aid is equipped with a filter. This filter is located at the front and top of the aid and prevents moisture and debris from getting into the hearing aid. If the hearing aid seems to have lost power and changing the battery does not correct the situation, the

filter may be blocked and needs to be changed. Use the repair/return form available to download at HearingDirect.com.

If it is necessary to store your hearing aids for an extended amount of time, follow the steps below for proper storage.

1. Remove the batteries.

2. Clean the aid according to the instructions on page 12.

3. Place the aids in a cool, dry place. Either their original container or a hearing aid dehumidifier is recommended.

Extended

storage

You may use your HearingDirect.com hearing aid with either a mobile or landline telephone. Finding the optimal position for holding a telephone may require practice for some individuals, and one or more of the following suggestions may be helpful.

Hold the phone up to your ear as you would normally or you may want to try holding the telephone towards the top of the ear (closer to where the microphone is). If the hearing aid whistles, try repositioning the phone receiver so that it is not against the ear or completely covering the hearing aid. Individual differences in hearing loss, ear shape and size may influence how much hearing benefit your

HearingDirect.com hearing aid can provide when used with a phone.

Telephone

These hearing aids feature multiple volume memory settings for different listening situations. The push-button control is used to switch between memories that have been programmed. Simply select your preferred option.
