After a successful interconnection, "SLAV" will be lit continuously on the display of the given speaker, which means that both speakers are paired with each other and connected to each other. One speaker will reproduce the left channel and the second right channel speaker.

The speaker on which “BLUE” is lit is the host speaker, and the speaker labeled “SLAV” will be a connected speaker (Slave).

4 On your Bluetooth device (phone, tablet, etc.), search for available Bluetooth devices. For details, refer to the operating instructions of the device.

When Crater L appears on the display of your Bluetooth device, select it and wait until a confirmation message with the Crater L appears on the display of your Bluetooth device and a beep sounds from that device and the Blue indicator stops flashing and stays lit.

Now both speakers can simultaneously play music via Bluetooth in real stereo sound.

Follow the steps in "Playing via Bluetooth from a Bluetooth Device" to play.

5 Disconnect two paired speakers

To clear the TWS pairing memory, press and hold ▷.

Notes:

• This function requires 2 Crater L speakers on.
• If no Crater L speaker is connected to another Bluetooth device before TWS pairing, you will need to pair.
• If both Crater L speakers have already been paired with another (third) Crater L speaker, the TWS pairing memory must be cleared first, otherwise the two speakers cannot be paired successfully.
  Press and hold ▷ on both of these speakers to clear their pairing memory.

More details

Wireless BLUETOOTH technology

BLUETOOTH wireless technology is a short-range technology that enables wireless data communication between digital devices such as PC and digital camera. Wireless BLUETOOTH technology works within a range of about 10 m.

The two devices are connected to each other, but some devices can be connected to more than one device at a time.

No cable is required for the connection, nor is it necessary to place the devices opposite each other as with infrared technology. For example, you can use the device even if it is in a backpack or pocket.

The BLUETOOTH standard is an international standard supported and used by many companies around the world.

Maximum communication range

The maximum communication range may be shorter in the following conditions. There are obstacles such as people, metal or a wall between this system and the BLUETOOTH device.

A LAN device is used near this system. A microwave oven is used near this system.

Electromagnetic radiation generating equipment is used near this system.

Interference from other devices

BLUETOOTH and wireless LAN (IEEE802.11b / g) devices use the same frequency, so if you use this system near a wireless LAN device, microwave interference may occur, which may result in poor communication speed, noise, or poor connection. In this case, do the following.

Use this system at least 10 m from a wireless LAN device.

If you use this system less than 10 m away from the wireless LAN device, turn off the wireless LAN device.

Interference from other devices

Microwaves emitted by BLUETOOTH devices may affect the operation of electronic medical devices. Turn off both the system and the BLUETOOTH device in the following places, as there is a risk of danger.

Near flammable gases, in hospitals, trains, planes or petrol stations.

Near automatic doors or fire alarms.

Notes

- In order to use the BLUETOOTH function, the connected BLUETOOTH device must have the same profile as this system.

- Even if the profiles are the same, the devices may work differently depending on their specifications.

- Due to the characteristics of wireless BLUETOOTH technology, the sound reproduced by this system is slightly delayed compared to the sound from the BLUETOOTH playback device during a telephone call or listening to music.

- This system supports security standards that comply with BLUETOOTH standards to ensure a secure connection when using BLUETOOTH wireless technology. However, depending on your settings, security may not be enough. Be careful when communicating using BLUETOOTH wireless technology.

• We are not responsible for information leakage during BLUETOOTH communication.

- A device with BLUETOOTH function is required to ensure compliance with BLUETOOTH standards specified by the Bluetooth SIG standard and authentication. Even if the connected device complies with the above BLUETOOTH standards, some devices may not be able to be connected or may not work properly depending on the functions or technical specifications of the device.

- Depending on the BLUETOOTH device connected to this system, the communication environment, or the operating environment, noise or outages may occur.

Troubleshooting

Warning:

If you're having trouble with this device, try this report. If precautions do not help, do not attempt to remove the device cover or repair it yourself. There is a risk of electric shock.

Bluetooth connection issues

Bluetooth signal is interrupted:

The effective distance between the speakers and the device is up to 10 m.

The signal will be interrupted if the distance between the Bluetooth device and the speakers is more than 10 m.

The Bluetooth device will find several other Bluetooth devices during the search:

Wait for the search to complete and select “Crater L” to pair. Do not hold the mobile device too close to the speaker when using the phone to avoid echo (feedback).

There is no sound from the microphone
