Hearing Safety

To prevent hearing damage, limit the time you use the headphones at high volume and set the volume to a safe level. The higher the volume, the shorter the safe listening time.

• Listen at a reasonable volume for reasonable periods.
• Be aware of your hearing as you adapt to the volume.
• Do not turn the volume so high that you cannot hear surrounding sounds.
• Use caution or temporarily discontinue use in potentially hazardous situations.
• Excessive sound pressure from headphones can cause hearing loss.
• It is recommended not to wear both earbuds while driving, as this may be illegal in some areas.
• For safety reasons, avoid letting music or phone calls distract you while driving or in other potentially hazardous environments.

General Information

Pairing Your Earbuds with a Bluetooth Device for the First Time

1. Ensure the earbuds are fully charged and powered off.
2. Open the charging case lid and take out the earbuds. The earbuds will power on automatically. The master earbud's LED will flash blue and white alternately, while the other earbud's LED will be off.
3. The earbuds are now in pairing mode and can be paired with Bluetooth devices (e.g., your phone).
4. Turn on the Bluetooth function on your device.
5. Pair the earbuds with your Bluetooth device. Refer to your device's user manual.

Example Pairing Process:

1. Turn on the Bluetooth function on your device and select "Philips TAQ4120".
2. If prompted for a passcode, enter "0000" (four zeros). For devices with Bluetooth 3.0 or higher, a passcode is not required.

? Note: If the earbuds are powered on and do not find any previously connected Bluetooth devices, they will automatically enter pairing mode after approximately 15 seconds. You can then find and connect to the earbuds via your phone.

Single Earbud (Mono Mode)

Take out either the left or right earbud from the charging case for mono mode. The earbud will power on automatically.

? Note: Taking out the second earbud from the charging case will automatically pair both earbuds.

Pairing with Another Bluetooth Device

If you want to pair another Bluetooth device with your earbuds, simply disconnect the currently connected Bluetooth device and follow the standard pairing procedure with the new device.

? Note: The earbuds can store up to 4 paired devices. If you attempt to pair a fifth device, the earliest paired device will be replaced by the newest one.

Connecting to Bluetooth Devices

1. Turn on the Bluetooth function on your device.
2. Open the charging case lid and take out the earbuds. The white LED indicator will flash.
3. The earbuds will search for the last connected Bluetooth device and automatically reconnect. If the last connected device is unavailable, the earbuds will automatically enter pairing mode. You can then find and connect to the earbuds via your phone.

? Note: If you turn on the headphones before turning on the Bluetooth function on your device, you may need to manually connect the headphones via your device's Bluetooth menu.

? Note: On some Bluetooth devices, the headphones may not connect automatically. In such cases, go to your device's Bluetooth menu and manually connect the headphones.
