Frequently Asked Questions - PHLHA48 Pyle

How do I adjust the volume on my Pyle PHLHA48 hearing aid?

Use the volume knob located on the device. Gently rotate it upwards to increase volume or downwards to decrease. Start at position 2 or 3 to test normal function.

What should I do if my hearing aid produces a whistling sound?

Whistling (acoustic feedback) can be reduced by: lowering the volume, ensuring the earplug fits snugly (try a larger size), or gradually turning up the volume after placing the device away from your ear to avoid reflection.

How do I change the battery?

Open the battery compartment, remove the old battery, and insert a new DC 1.4V battery with correct polarity. Close the compartment securely.

How should I clean my hearing aid?

Use the provided cleaning brush to remove dust from the sound hole and microphone. Wipe the enclosure with a dry cloth or a cloth slightly dampened with special hearing aid detergent. Avoid liquid entering the device.

Who should not use this hearing aid?

Do not use if you have acute otitis externa, eardrum inflammation, chronic suppurative otitis media (active infection), or allergies to the materials. It is not suitable for non-air conduction hearing loss or severe hearing impairment.

How do I select the correct earplug size?

The device comes with three earplug sizes (small, medium, large). Choose the one that fits your ear canal snugly to prevent sound leakage and whistling. Users with larger ear canals should use the large size.

Can I wear the hearing aid while showering?

No, remove the hearing aid before showering. Store it in a cool, dry place. Avoid exposure to water, high humidity, or temperature extremes.

What should I do if the volume becomes too low?

Low volume often indicates a low battery. Replace the battery with a new one. Also check that the volume knob is set correctly and the sound hole is not clogged.

How should I store the hearing aid when not in use?

Turn off the power and store in a cool, dry place. Avoid direct sunlight, heat, and high magnetic fields. Keep out of reach of children to prevent choking hazards.

Is it normal to hear my own voice louder when first using the hearing aid?

Yes, first-time users may experience ear fullness or heightened own voice. This usually subsides within three months as you adapt. Adjust the earplug fit and volume to comfort.

II. APPLICATION SCOPE

Used for hearing compensation of air-conduction hearing loss suffers

III. USING METHOD

1. SEE THE POSITION AS SHOWN IN THE FIGURE

VOLUME ADJUSTMENT

BATTERY INSTALLATION

2. VOLUME ADJUSTMENT

Firstly, adjust the volume knob to the position of 2 or 3 to test whether the volume of hearing-aid is normal:

Use the thumb to press the knob to rotate upwards or downwards lightly and slowly to the appropriate sound.

3. SELECTION OF THE APPROPRIATE EARPLUG

The appropriate earplug shall be selected. Users with large ear canal select the large earplug. Earplugs with three different sizes are equipped with the device (ensuring the close fit of earplug and ear canal. Otherwise, it will give rise to the sound feedback, causing whistler accordingly)

4. WHISTLER

It's also called acoustic feedback, which is a normal phenomenon occurring in working of hearing aid. It is more likely to occur to the one with larger power and higher power. In the event of it, the following methods shall be used for improvement:

1. Reduce the volume
2. Fit the earplug and air canal closely or replace with larger earplug, ensuring the sound not leaked or leaked as little as possible
3. Turning up gradually, and then leave the hand away from the ear, avoiding acoustic reflection. At this moment, the whistler will be controlled.

IV. METHOD OF USE ACCESSORIES

Select the appropriate earplug according to the size of ear canal

clear the hearing-aid regularly according the method as shown in the figure
