Step 1: Charge or Install Batteries
If your Matrix model is rechargeable:
Place both devices in the charging case, aligning the contacts.
Plug in using the included cable.
Allow 2–3 hours for a full charge before first use.
If your Matrix model uses disposable batteries:
Open the battery door on each device.
Insert the appropriate battery size (check your model's guide — typically size 312 or 13).
Close the battery door firmly. The device will power on automatically.
Step 2: Select Your Ear Tips
Try the medium dome first.
Insert by pulling the outer ear gently upward and back, then placing the dome in the ear canal.
The fit should feel secure with no pressure pain. Try other sizes if needed.
Step 3: Power On
Rechargeable models: Power on automatically when removed from case.
Battery models: Close the battery door to power on.
You'll hear a confirmation tone in both ears.
Step 4: Bluetooth Pairing
Ensure Bluetooth is enabled on your phone.
For iPhone: Go to Settings → Accessibility → Hearing Devices.
For Android: Go to Settings → Connected Devices → Pair New Device or Accessibility → Hearing Aids.Your Matrix aids should appear in the list. Tap to pair.
Follow any on-screen prompts.
Download the Matrix companion app if available for your model.
Step 5: Adjust and Explore
Use the physical button or the companion app to cycle through listening programs (e.g., quiet, noisy environment, TV streaming).
Start in a comfortable, quiet setting for your first few hours.
Allow yourself 1–2 weeks to fully acclimate to amplified sound — this is completely normal.
Getting the Most Out of Your Matrix Aids
Clean ear tips and domes regularly (see our Cleaning and Maintenance article).
Store in their case when not in use.
Keep away from moisture unless your model is rated water-resistant.
