● The light stick will not function properly during the concert if the seat information is not registered. If the seat information cannot be entered through the app, please visit the help desk at the venue on the day of the concert.

● Malfunction may occur if the batteries are not properly inserted into the light stick.

● Throughout the concert, the light stick will be controlled by our system and the LED will light up in various colors.

● The connection of the Bluetooth ranges up to 10 meters. However, the effective range can vary depending on obstacles (people, metal, walls, etc.) and signal conditions.

● A Bluetooth antenna is built into the light stick. The sensitivity of the Bluetooth connection can be heightened by pointing the built-in Bluetooth antenna towards the Bluetooth device. If there is an obstacle between the device and the light stick, data may not be properly received.

● Wireless connection may fail under the following conditions:

‐ When the light stick is covered with metal, etc. – When the light stick is inside a pouch or bag.

‐ When the light stick is used in wireless LAN environment (microwave, mobile phone, or other environment affected by radio waves).

– When the light stick’s built-in antenna is covered by hands or surrounded by people. ‐ When there are other wireless connection problems.

● Since Bluetooth and Wi-Fi (IEEE802.11b / g) devices use the same frequency (2.4GHz), using Bluetooth near other wireless LAN devices may cause signal interference. In this case, follow the steps below:

1. When connecting the light stick to a Bluetooth device, keep it at least 10 meters away from other wireless LAN devices.

2. Place the light stick and the Bluetooth device as close as possible. Turn off the wireless LAN device when trying to connect to Bluetooth near the wireless LAN device (within about 10m).

3. The RF emitted from Bluetooth devices can affect the operation of devices such as electronic medical devices.

4. To create a safe Bluetooth connection, the light stick supports safety functions that comply with the Bluetooth standards, but depending on its settings, these safety functions may not be sufficient. Be careful when connecting to Bluetooth.

● We shall not be responsible for the lack of information on the use of the Bluetooth technology.

● We shall not guarantee that the light stick can be connected to all Bluetooth devices.

● The Bluetooth device used for connection must comply with and should be certified to the Bluetooth standards specified by the Bluetooth SIG.

● Even if the connecting device complies with the above Bluetooth standards, the device may not be connected or function properly depending on the functions and specifications of other devices.

● Depending on the connecting device, it may take some time to set up the Bluetooth connection.
