• The blue LED indicator goes out when the battery is fully charged.

• After charging, remove the in-ear headphones from the charging bays in the charging case.

• Disconnect the charging case from the USB power adapter or other USB power source, if applicable. c) Using the in-ear headphones

• Select the most suitable ear bud from the 2 supplied sizes and place it over the sound outlet on the earphone (4). Place both in-ear headphones into your ears. Observe the markings ‘L’ and ‘R’, with ‘L’ for the left ear and ‘R’ for the right ear.

• The microphones (3) on the headphones must point downwards towards your mouth.

• The area next to the microphone is a sensor area (5). This sensor area acts as a touch button for controlling different functions of the in-ear headphones. A light press is all that is required to use it. d) Switching on the in-ear headphones and stereo pairing

• The in-ear headphones are designed for stereo pairing (TWS). To pair the in-ear headpho- nes after charging, insert them into the charging bays in the charging case and remove them again after a short time. After removal, the headphones switch on automatically and stereo pairing begins. A conrmation tone conrms that the headphones have been paired successfully.

• If stereo pairing of the right and left earphones is not successful within 3 minutes, the headphones switch off automatically. Start another pairing attempt by briey inserting the headphones into the charging bays in the charging case. e) Pairing the in-ear headphones with a Bluetooth device Automatically pairing the in-ear headphones Both devices must be paired before wireless transmission between your Bluetooth device (audio device) and the product (in-ear headphones) is possible. This process is also called ‘pairing’.

• Place the in-ear headphones and your Bluetooth audio device at a distance of approxi- mately 1 m from one another and avoid interference that may affect signal transmission (for example, do not place the devices near strong electromagnetic elds or metal objects or be- hind reinforced concrete walls). If necessary, switch off other interfering Bluetooth devices.

• Ensure that the Bluetooth function is switched on and that your Bluetooth device has all of the necessary Bluetooth drivers installed. Visit the manufacturer's website to download and install the latest drivers.

• Switch the Bluetooth device on and enable pairing mode.

• Follow the instructions for your Bluetooth device to pair it. These may vary depending on the manufacturer and design. The device now searches for Bluetooth devices within reception range.

1. To enter pairing mode, remove the in-ear headphones from the charging case. If necessary,

insert them briey into the charging case for activation, then remove again. Stereo pairing begins automatically.

2. The LED indicator on both in-ear headphones (5) ashes red and blue alternately to indi-

cate that pairing mode is active. A sound indicates that stereo pairing has been successful. You can also remove only one headphone from the charging case and pair it with the mobile device individually. In that case, stereo sound will not available as stereo pairing will not have been completed.

3. Select the device ID of the in-ear headphones (‘RF-TWS-500’) in the list of available Blu-

etooth devices on your audio device (e.g. mobile phone, laptop) to pair the in-ear head- phones with the device. You will hear a brief conrmation sound once pairing has been successful.

4. If the devices do not pair, insert the in-ear headphones into the charging case and try pairing

the devices again. If you move your mobile device and in-ear headphones out of range, you will hear a warning sound. The product then tries to connect to the mobile device again. If the- se connection attempts remain unsuccessful for 3 minutes, the in-ear headphones switch off automatically. Manually pairing the in-ear headphones (True Wireless Stereo)

1. Ensure that the cover on the charging case is closed.

2. To enter pairing mode on the in-ear headphones, briey touch the sensor area (5) of the

right and left headphones twice at the same time. Stereo pairing begins. The red and blue LEDs ash.

3. As soon as the right and left headphones are connected, open the charging case to pair

a mobile device with the in-ear headphones via Bluetooth. The red and blue LEDs of both headphones begin to ash alternately. Use your mobile device to search for the in-ear head- phones (ID ‘RF-TWS-500’) and pair them with the device. A conrmation sound indicates that pairing was successful. If you delete the paired in-ear headphones from the list of paired devices on your mobile device, you must also complete stereo pairing again. Otherwise, you will only hear audio from one in-ear headphone. f) Control with your mobile device You can control all functions, such as playback and other functions, using the con- trols on your audio device (mobile device). See the operating instructions for your device. g) Music playback

• Connect the in-ear headphones to an audio playback device via Bluetooth.

• Start playback on your audio device.

• You can select the volume and track (skip to the next/previous track) with your audio device.

• While playing a track, briey touch the sensor area (5) of one of the headphones twice to pause the track. Press again twice to resume the track/audio le. h) Answering/ending phone calls and dialling When the products is paired with a mobile phone via Bluetooth and you receive an incoming call, the current track is paused and the speaker plays a ringtone.

• To answer an incoming call, briey touch the sensor area (5) of the right or left headphone twice. You will hear a beep.

• To end the call, briey touch the sensor area (5) of the right or left headphone twice. You will hear a beep. The call is terminated.

• To cancel dialling, briey touch the sensor area (5) of the right or left headphone twice. You will hear a beep. The dialling attempt is aborted.

• To reject a call, use the controls on your mobile device.

• Use the usual controls on your mobile device to answer your calls, such as redialling the last number that you dialled, etc. If possible, speak in the direction of the microphone (3) when making a call and ensure that the microphone is not obstructed.

i) Changing the volume

You can adjust the volume settings using the controls on your audio device. j) Troubleshooting Problem description Possible cause Solution The headphones cannot be switched on. The batteries are at. Insert the headphones into the charging case. (If the charging case no longer has power, charge the case with the charger rst). The headphones cannot be charged. The charging contacts on the headphones are not properly connected with the pins in the charging case. Remove your headphones, adjust the charging con- tacts slightly and insert the headphones back into the charging case. Ensure that the charging contacts are properly con- nected with the pins in the charging case. The headphones cannot be switched off. The software requires a restart due to improper operation. Insert the earphones into the charging case to reset them. The headphones cannot be found or pairing fails. The headphones do not en- ter pairing mode. Activate the headphones to enter pairing mode. Refer to the section ‘e) Pairing the in-ear headphones with a Bluetooth device’. The Bluetooth function on the device being paired is deactivated. Activate the Bluetooth func- tion on your device to pair the mobile device with the in-ear headphones again. Keep the in-ear headphones away from credit cards and magnetic storage media. Data on these devices could be lost due to demagnetisation.

• Ensure that all of the latest Bluetooth drivers are installed on the device that you want to pair.

• Please note that the control functions on the in-ear headphones are not supported by all audio devices (e.g. smartphones). Visit the website of your smartphone manufacturer and check the list of functions for your device (the AVRCP protocol must be supported). Up- dating your device may help to resolve the issue.

• If there is no audio in the in-ear headphones, try increasing the volume. If the issue persists, re-establish the Bluetooth connection or pair the devices again.
