Philips TAT1138 True Wireless Headphones

Important Safety Instructions

Hearing Safety

Danger

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

When using headphones, follow these guidelines:

• Listen at a reasonably adjusted volume for a reasonably long period.
• Be cautious and do not constantly increase the volume, as your hearing adapts.
• Do not set the volume so high that you cannot hear what is happening around you.
• In potentially dangerous situations, be cautious or stop using the headphones temporarily.
• Excessive acoustic pressure from headphones can cause hearing loss.
• Using headphones that cover both ears is not recommended while driving. This may be illegal in some regions.
• In traffic or other potentially dangerous environments, for your own safety, prevent music or phone calls from distracting you.

General Information

Caution

• Do not expose the headphones to excessive heat.
• Do not drop the headphones.
• The headphones must not be exposed to dripping or splashing water. (Refer to the IP rating of the specific product.)

• There is a risk of explosion if the battery is replaced incorrectly. Replace the battery only with the same or an equivalent type.
• To achieve the stated IP rating, the charging slot cover must be closed.
• Disposing of a battery in a fire or hot oven, or mechanically crushing or cutting it, may result in an explosion.
• Leaving a battery in an environment with extremely high temperatures can cause an explosion or leakage of flammable liquid or gas.
• A battery exposed to extremely low air pressure may result in an explosion or leakage of flammable liquid or gas.
• To prevent fire hazards, the device is powered only by an external power source with a PS1 output (output capacity less than 15 W).

• 2 Multi-function button (MFB)
• 3 LED indicator (charging case)
• 4 USB-C port for charging

Getting Started

Charging the Battery

Charging Case

Connect one end of the USB-C cable to the charging case and the other end to a power source.

Earphones

Remove the earphones and peel off the insulation stickers. Place the earphones back into the charging case and close the lid. The earphones will then start charging.

Tip: The charging case serves as a portable power bank for charging the earphones. When the charging case is fully charged, it can fully charge the earphones 3 times.

Tip: Under normal conditions, it takes 2 hours to fully charge via USB cable (earphones or charging case).

Note: Before using the earphones, place them in the charging case and charge the battery for 2 hours to achieve optimal capacity and lifespan. Use only the original USB-C charging cable to prevent any damage. End the call before charging. The earphones will turn off when connected for charging. If the earphones are not used for a long time, the rechargeable battery will start to lose its charge. To prevent this loss, fully charge the battery at least once every three months.

How to Wear

Inserting Earphones into Ears

1. Check if the earphone is left or right.
2. Insert the earphones into your ears and rotate them slightly until they fit securely.

First-time Pairing with Bluetooth Device

1. Ensure the earphones are fully charged and turned off.
2. Open the charging case cover. Remove the earphones.

The LED indicators on both earphones will start flashing alternately white and blue. The earphones are now in pairing mode and ready to be paired with a Bluetooth device (e.g., mobile phone).

3. Turn on the Bluetooth function on your Bluetooth device.
4. Pair the earphones with the Bluetooth device. Refer to the user manual of your Bluetooth device.

Note: If the earphones cannot find a previously connected device after turning on, they will automatically enter pairing mode.

Pairing Earphones with Another Bluetooth Device

If you want to pair the earphones with another Bluetooth device, simply press and hold the MFB button on both earphones for 5 seconds to put the earphones into pairing mode. Place them back into the charging case and then remove them from the charging case again. Recognize the second device as during normal pairing.

Single Earphone (Mono Mode)

To use mono mode, remove either the right or left earphone from the charging case. The earphone will turn on automatically.

Note: The voice assistant is disabled in mono mode. When the second earphone is removed from the charging case, both earphones will automatically pair with each other.

Note: The earphones store up to 4 devices. If you try to pair more than 4 devices, the oldest paired device will be replaced by the new one.

Using the Earphones

Connecting Earphones to a Bluetooth Device

1. Turn on the Bluetooth function on your Bluetooth device.
2. Remove the earphones from the charging case.

The blue LED indicator will start flashing. The earphones will search for the last connected Bluetooth device and automatically reconnect. If the last connected device is not available, the earphones will enter pairing mode.

Tip: The earphones can only be connected to 1 device at a time. If you have paired two Bluetooth devices, enable Bluetooth only on the device you want to connect to. If you enable the Bluetooth function on the Bluetooth device only after turning on the earphones, you will need to go to the Bluetooth device's menu and connect the earphones manually.

Note: If the attempt to connect to a Bluetooth device fails within 3 minutes, the earphones will automatically turn off to save battery life. For some Bluetooth devices, the connection may not be automatic. In such cases, you need to go to the Bluetooth device's menu and connect the earphones manually.
