3. Setup
3.1 Initial Programming
The Rexton Targa P/HP 5 is a computer-programmable device. For optimal performance, it requires professional programming based on your individual audiogram. Please consult with your hearing care professional for initial setup and adjustments. If purchasing online, you may need to provide your audiogram to the seller for remote programming.
3.2 Battery Insertion
To insert or replace the battery:
- Gently open the battery compartment door.
- Insert a fresh standard hearing aid battery (typically size 675 for P/HP models) with the positive (+) side facing up.
- Close the battery compartment door firmly until it clicks into place.
3.3 Fitting the Hearing Aid
The Targa P/HP 5 models come with an ear hook. Ensure the ear hook is securely attached to the hearing aid. The lightweight earmold option provides a secure fit and directs sound effectively into your ear. Place the hearing aid behind your ear and gently insert the earmold into your ear canal.
4. Operating Instructions
4.1 Power On/Off
To turn the hearing aid on, fully close the battery compartment door. To turn it off, open the battery compartment door slightly.
4.2 Volume and Program Adjustment
Use the rocker switch on the hearing aid to:
- Adjust Volume: Press the top part of the rocker switch to increase volume, and the bottom part to decrease volume.
- Change Programs: A short press on the rocker switch may cycle through different listening programs (e.g., quiet environment, noisy environment, music). Your hearing care professional will program these settings.
4.3 TeleCoil Function
In places equipped with an induction loop (often indicated by a 'T' symbol), you can activate the TeleCoil function to hear speakers more clearly. Select the 'T-program' using your rocker switch or app, if available. This streams audio directly from the induction loop to your hearing aid, reducing ambient noise.
4.4 Multi-Channel Information Processing
Figure 4: The hearing aid's multi-channel processing helps distinguish speech from noise in various environments like home, quiet settings, and outdoors.
The Targa P/HP 5 utilizes multi-channel information processing to distinguish speech from noise, even in challenging environments. This allows for better listening experiences in various situations.
4.5 Optional Audio Shoe
For enhanced listening in very noisy environments, you can replace the battery housing with an optional audio shoe. This allows a speaker's voice to be streamed directly to your ears via an external microphone, bypassing much of the ambient sound.
5. Maintenance
5.1 Daily Cleaning
- Wipe the hearing aid daily with a soft, dry cloth to remove earwax and debris.
- Use a small brush or wax pick to clean the earmold and ear hook openings.
- Ensure the microphone ports are clear of any obstructions.
5.2 Moisture and Dust Protection
Figure 5: The Nano coating resists water vapor, sweat, and dust, enhancing the device's longevity.
The Targa P/HP 5 features a nano coating that resists moisture, sweat, and dust. While this provides excellent protection, it is not waterproof. Avoid submerging the hearing aid in water and remove it before showering or swimming. Store the hearing aid in its case when not in use, preferably with the battery compartment open to allow air circulation and prevent moisture buildup.
5.3 Battery Care
- Always use the correct size and type of battery.
- Remove depleted batteries immediately to prevent corrosion.
- Store new batteries in a cool, dry place, away from children and pets.
6. Troubleshooting
6.1 No Sound or Weak Sound
- Check if the battery is inserted correctly and is not depleted. Replace if necessary.
- Ensure the battery compartment is fully closed.
- Check for earwax or debris blocking the earmold or ear hook. Clean thoroughly.
- Verify the volume setting is appropriate.
- Confirm the correct program is selected.
6.2 Whistling or Feedback
