TE102 Digital Hearing Aid

The TE102 is a digital RIC hearing aid featuring advanced digital signal processing, 50-channel WDRC (Wide Dynamic Range Compression), and 50 EQ channels. It's designed for people with mild to moderate-severe hearing loss.

Unlike simple amplifiers that boost all sounds equally, the TE102 intelligently processes different frequencies to provide clear, natural sound quality.

Getting started is easy:

1. Charge the charging case fully
2. Open the case lid and remove the hearing aids
3. The aids will automatically power on and activate hearing mode in about 7 seconds
4. Choose the right ear tips and wear them securely
5. Start with Volume Level 1 and adjust gradually

The TE102 has 8 volume levels:

Default: Volume Level 1 (20dB) out of the box.

The charging case has 4 touch buttons below the screen:

• Left side (+/-): Controls left ear volume
• Right side (+/-): Controls right ear volume

When you change volume, you'll hear a "beep" confirmation sound, and the screen will display the current level. You can also adjust via the mobile app.

Long press any "+" button for 3 seconds to cycle through the 4 scene modes:

Each mode has a unique voice prompt when selected.

Yes! The TE102 comes with the CJ-A01 TV Companion as standard. It uses low-latency wireless technology to transmit TV audio directly to your hearing aids with a range of up to 15 meters in open spaces.

When powered on, the hearing aids automatically search for Auracast broadcasts for 5 minutes. Once found, they'll automatically connect and you'll hear a "beep-beep-beep" confirmation sound.

It depends on your TV:

• If your TV supports Bluetooth: No TV Companion needed! Connect your hearing aids directly via Bluetooth.
• If your TV doesn't have Bluetooth: You'll need the TV Companion. Connect it to your TV with a cable, and it wirelessly transmits audio to your hearing aids.
• Alternative: You can also simply wear your hearing aids while watching TV without any special connection.

This depends on your TV's audio output settings. Most TVs stop external audio when connected to Bluetooth devices or a TV Companion.

Options for watching together:

• Check TV settings for "Simultaneous Audio Output" or similar options
• If not available, enable the TV Companion's microphone mode to pick up external sound

When connected, there are two types of sound:

The TV Companion has its own power supply and continues broadcasting even when the TV is off. When the TV turns off, it stops sending audio to the TV Companion, but the Companion keeps transmitting "empty" signals.

What to do:

• To restore normal hearing: Turn off the TV Companion (or unplug it). The hearing aids will beep and automatically restore normal hearing mode.
• To continue watching: Simply turn the TV back on. Audio will resume automatically.

Yes! The TE102 supports Bluetooth 5.3. To connect:

1. Open your phone's Bluetooth settings
2. Search for "CZ-B801"
3. Connect to the device
4. You'll hear "Connect" voice prompt
5. Use the app to view device info and control settings

Reset options:

• Clear pairing: With aids in case (lid open), press button near Type-C port for 3 seconds
• Re-pair left/right aids: Press same button for 8 seconds
• Factory reset: Remove aids from case, press button for 16 seconds

The hearing aids have IP22 water resistance — suitable for light sweat or minor splashes. The charging case is not waterproof.

Regular maintenance:

• Clean ear tips regularly
• Keep sound outlet clean
• Check and clean wax guard
• Keep charging contacts dry and clean

No manual activation needed! UV disinfection starts automatically when:

1. Hearing aids are placed in the case
2. The case lid is fully closed
