Safety Warnings

• Only use the supplied power adapter or a certified USB-C power adapter (5V DC, 3A or higher) with this lamp. Otherwise this lamp will not work properly and may even cause a fire.
• Do not place or hang any objects on this lamp, so as to avoid malfunction of this lamp.
• Route the USB-C power cord so as to avoid it from being pinched by items placed upon it or against it.
• If this lamp will not be used for an extended period of time, remove the USB-C power cord from the USB port and turn off the power of the wireless controller.
• This lamp is suitable for indoor use only.

• The wireless controller of this lamp has a built-in rechargeable lithium battery. Pay special attention to the following matters when using this lamp:

• Do not allow the wireless controller to be hit, dropped or placed in a high/low temperature environment (e.g., near a fire/heat source or in a closed car under the sun) to prevent the battery from being damaged or heated and causing a fire or explosion.

• If the wireless controller will not be used for a long period of time, charge it at least once a month or slide the power switch on the bottom of the wireless controller to OFF in order to avoid damage to the battery due to over-discharge.
• Rechargeable batteries are consumables and it is normal that their capacity will gradually decrease over time and with the number of times they are used.
• When travelling by air, remember to place this lamp in your carry-on baggage, not in checked baggage.

- This lamp is not suitable for USB-A port power supply. Insufficient power supply will cause the lamp to flicker.

- If this lamp is powered by a device other than the supplied power adapter, such as a monitor, laptop, desktop, USB hub, etc., it may be susceptible to an abnormality due to insufficient power supply. If this happens, use the supplied power adapter instead.

CAUTION

- If you encounter the following situations, please remove the USB-C power cord from the USB port immediately, and seek support from an authorized service agent or qualified technician:

• When the casing of this lamp is damaged
• When this lamp emits an abnormal smell
• When the LED light source flickers abnormally

• When the power cord is damaged or the wire inside is exposed

• Do not expose this lamp to humid environments (such as bathrooms, outdoors) to avoid short circuits and accidents.

Charging the Wireless Controller

Use a USB-C cable (not supplied) to connect the USB-C port on the wireless controller to the supplied power adapter or a certified USB-C port power supply (5V'DC/1A or higher) to start charging the wireless controller.

• When charging, the power indicator on the wireless controller will light up red.
• When fully charged, the power indicator will light up green.

- If the power indicator blinks red while the wireless controller is in use, the power level is too low. Charge the wireless controller as soon as possible.

- If the power indicator blinks red and green alternately during charging, it indicates abnormal charging. Use the supplied power adapter or replace the USB-C power cable. If the blinking persists, stop charging and seek support from an authorized service dealer or qualified technician.

- The wireless controller is not recommended to be charged from a USB-A port. Insufficient power supply will cause the power indicator to blink.

- Connect the wireless controller to a USB-C port that provides more than 5V DC/1A power to ensure proper charging.

- The wireless controller cannot be used as a mobile power source. Do not connect any other device to the USB-C charging port on the wireless controller.

- When fully charged, the wireless controller will provide approximately 3 months of standby time.

- If the battery is depleted, it will take about 120 minutes to fully charge the battery using a USB-C port with a power source of 5V DC/1A or higher.

- If you use the wireless controller while charging, the battery will take longer than 120 minutes to charge.

- If any of the following conditions occur while charging the wireless controller, stop charging immediately: liquid leakage, unusual odor, abnormally high heat, deformation of appearance, etc.

1. With the lamp on, tap and hold the Presence Detection button for 6 seconds. The Presence Detection indicator will blink.
2. Rotate the adjustment ring to adjust the away detection time: rotate the adjustment ring clockwise to extend the detection time, or rotate the adjustment ring counterclockwise to shorten the detection time. The current detection time setting is shown on the display panel in real time. You can adjust the detection time setting within 3, 5, 10 and 15 minutes.
3. If you finish the detection time setting, tap the Presence

Detection button again. The Presence Detection indicator and the Power indicator will flash. When they stop flashing, it means that the setting is memorized.

- The ultrasonic sensor will detect a conical area of 60 ± 10cm in front of the screen at a height of 50cm from the table.

- When the Presence Detection function is on, this function presets the light to turn off automatically after the user leaves the detection area for 5 minutes to save power.

- When the Presence Detection function is on, the Presence Detection (○) indicator light will flash for 30 seconds after the light is turned off manually, during which time the Presence Detection auto on/off function will be suspended. 30 seconds later the indicator light will turn off and the presence detection auto on/off function will resume normal operation, and the light will be turned on again automatically if you are still in the detection area at that time.

- Do not allow any object to block or cover the ultrasonic sensor on the lamp head to ensure that the Presence Detection function works properly.

- Do not insert or poke any objects into the ultrasonic sensor as this may affect the detection function.

- The Presence Detection function relies on the motion tracking technology. If you watch a movie in front of the screen for a long period of time in a fixed position, the sensor may determine that no one is present and turn off the lamp.
