Philips TAT1138 True Wireless Headphones

Hearing Protection

⚡ Pericol! To avoid hearing damage, limit the time you use the headphones at high volume and set the volume to a safe level. The louder the volume, the shorter the safe listening time.

Ensure you follow these guidelines when using the headphones:

• Listen at a comfortable volume for reasonable periods.
• Ensure you do not set the volume higher and higher as your hearing adapts.
• Do not turn up the volume so much that you cannot hear what is happening around you.
• Be cautious or temporarily discontinue use in potentially hazardous situations.
• Excessive sound pressure from headphones can cause hearing loss.
• Using headphones in both ears is not recommended while driving and may be illegal in some regions.
• For your safety, avoid distractions from music or phone calls while in traffic or other potentially hazardous environments.

General Information

⚠️ Attention! To avoid damage or malfunction:

• Do not expose the headphones to excessive heat.
• Do not drop the headphones.
• The headphones must not be exposed to damp environments (dripping or splashing). (Refer to the product's IP classification)
• The headphones must not be immersed in water.
• Do not charge the headphones when the connector or socket is wet.
• Do not use cleaning agents containing alcohol, ammonia, benzene, or abrasive substances.
• If cleaning is necessary, use a soft cloth and, if needed, slightly dampen it with a minimal amount of water or diluted mild soap.
• The built-in battery must not be exposed to excessive heat, such as from the sun, open flame, or similar heat sources.
• Risk of explosion if the battery is replaced incorrectly. Replace only with the same type or an equivalent.
• To achieve the specific IP protection rating, the charging port cover must be closed.
• Discarding a battery in fire or a hot oven, or mechanically crushing or cutting it, may result in an explosion.
• Exposing the battery to extremely high air pressure may result in an explosion or leakage of flammable liquid or gas.
• A battery subjected to extremely low air pressure may result in an explosion or leakage of flammable liquid or gas.
• To avoid fire risk, the equipment must be powered only by an external power source whose output complies with PS1 (with an output capacity of less than 15W).

Operating and Storage Temperatures and Humidity

• Store in a location where the temperature is between -20°C and 50°C, and relative humidity is up to 90%.
• Use in a location where the temperature is between 0°C and 45°C, and relative humidity is up to 90%.
• Battery life may be shorter in high or low temperature conditions.
• Replacing the battery with a different type risks severe damage to it and the headphones (e.g., in case of lithium battery types).

Charging the Battery

Note:

• Before using the headphones, place them in the charging case and charge the battery for 2 hours for optimal battery capacity and durability.
• Use only the original USB-C charging cable to avoid any malfunction.
• End the call before charging. Connecting the headphones to the charger will turn them off.
• If you do not use the headphones for a longer period, the battery will start to discharge. To avoid this, fully charge the battery at least once every three months.

In-ear Headphones

Recommendation: The charging case serves as a portable backup battery for charging the headphones. When the charging case is fully charged, it will fully charge the headphones three times.

Recommendation: Typically, a full charge takes 2 hours (for headphones or charging case) via USB cable.

Inserting the Earbuds

1. Check the orientation of the earbud (left or right).
2. Insert the ear tips into your ears and twist gently until they fit securely.

Pairing the Headphones with a Bluetooth Device for the First Time

1. The headphones must be fully charged and turned off.
2. Open the lid of the charging case. Remove the earbuds.

Diagram description: Shows opening the charging case and removing the earbuds.

➡️ The LED lights on both earbuds will flash blue and white alternately.

➡️ The headphones are now in pairing mode and can be paired with a Bluetooth device (e.g., a mobile phone).

3. Activate the Bluetooth function of your Bluetooth device.
4. Pair the headphones with the Bluetooth device. Consult the user manual of your Bluetooth device.

Note: After powering on, if the headphones cannot find a previously connected Bluetooth device, they will automatically enter pairing mode.

Single Earbud (Mono Mode)

Remove the left or right earbud from the charging case for use in Mono mode. The earbud will turn on automatically.

Note: Voice assistant is disabled in Mono mode.

Remove the other earbud from the charging case, and they will automatically pair with each other.

Note: The headphones store up to 4 devices. If you wish to pair more than 4 devices, the device that was paired longest ago will be replaced by the new device.

Connecting the Headphones to the Bluetooth Device

1. Activate the Bluetooth function of your Bluetooth device.
2. Remove the headphones from the charging case.

➡️ The blue LED light flashes.

➡️ The headphones will search for the last connected Bluetooth device and reconnect to it automatically. If the last connected device is not available, the headphones will enter pairing mode.

Recommendation:

• The headphones cannot connect to more than one device at a time. If you have two paired Bluetooth devices, turn on the Bluetooth function only on the device you wish to connect to.
• If you activate the Bluetooth function of your Bluetooth device after turning on the headphones, you will need to access the Bluetooth menu of the device and manually connect the headphones to the device.

Note:

• If you fail to connect the headphones to any Bluetooth device within 3 minutes, they will automatically turn off to save energy.
• On some Bluetooth devices, automatic connection may not occur. In this case, you need to access the Bluetooth menu of the device and manually connect the headphones to the Bluetooth device.
