2AI2E-SEEMEESEEMEE RADER TAILLIGHT

SEEMEE R300 USER MANUAL EN SEEMEE R300 IN THE BOX Seat post mount USB-C charging cable MJ-6556 Saddle mount (sold separately) WARNING ! START GUIDE 1. To prevent inadvertent switching on, please keep the light unit in lockout mode before transport or storage. 2. DO NOT disassemble, modify, remanufacture, puncture, or damage the device or batteries. 3. The SEEMEE R300 radar taillight does not replace cyclist attentiveness and good judgment. Always operate the bicycle in a safe manner. Failure to do so could result in severe injury or death. The SEEMEE R300 can be connected to bike computers with the radar ANT+ protocol. It includes both Lights ANT+ and Radar ANT+ protocols. The SEEMEE R300 radar taillight detects approaching vehicles up to 140 meters away. The radar detects approaching vehicle speed from 10 to 160 km/h (from 6 to 99 mph). NOTE: The radar does not detect vehicles traveling at the same speed as your bike. The radar detection angle is 35° horizontally and 45° vertically. The radar can detect up to eight approaching vehicles. ON/OFF: Press and hold the power button for 1 second to turn the taillight on/off. When the taillight is on, the radar function is activated by default. RADAR FUNCTION ON/OFF: 1. Press and hold the radar button for 1 second to turn the radar function on/off. 2. The radar function can be turned on/off separately. When only the radar is turned on, the taillight will enter only radar mode. RADAR INDICATOR: 1. When the radar is working, the indicator will circle clockwise with red light. 2. When the radar is abnormal, the indicator will keep flashing white. CHANGE MODE: When the taillight is on, click the power button to cycle through LowHighNight FlashDay Flash Eco FlashLow... OPERATION INSTRUCTIONS The SEEMEE R300 can be connected to bike computers with the radar ANT+ protocol. It includes both Lights ANT+ and Radar ANT+ protocols. The SEEMEE R300 radar taillight detects approaching vehicles up to 140 meters away. The radar detects approaching vehicle speed from 10 to 160 km/h (from 6 to 99 mph). NOTE: The radar does not detect vehicles traveling at the same speed as your bike. The radar detection angle is 35° horizontally and 45° vertically. The radar can detect up to eight approaching vehicles. PAIR WITH A BIKE COMPUTER Note: Place your bike computer and taillight within 3 meters. Keep 10 meters away from other ANT+ sensors when pairing. 1. Turn on SEEMEE R300 and activate its radar function. 2. Turn on your bike computer, go to Menu>Sen- sors>Add Sensors> Radar>Search All. 3. Select SEEMEE R300 (random number), and click "Add". 4. When pairing successfully, the sensor shows that "Radar" and "Lights" are connected. With a connected bike computer, enter "Light Mode" and select the corresponding brightness level. Or customize the taillight lighting mode on a compatible computer, e.g., automatically adjust the lighting mode and brightness according to ambient light. MEMORY FUNCTION: When the taillight is turned on again, it will automatically turn to the last selected lighting mode. VIBRATION FUNCTION ON: When the taillight is off, press and hold the power button and radar button for 3 seconds until the taillight lights up constantly at maximum output. When the vibration function is on, the taillight will enter sleep mode after 5 minutes of inactivity and automatically activate when a vibration is detected. When the taillight detects vibrations, it will automatically turn on and light up with the last selected lighting mode. VIBRATION FUNCTION OFF: When the taillight is off, press and hold the power button and radar button for 3 seconds until the taillight keeps flashing quickly at maximum output. LOCKOUT/UNLOCK: Press and hold the power button for 3 seconds to enter lockout mode and all other functions will be temporarily deactivated. Click the power button or radar button, and the indicator will flash red. In lockout mode, press and hold the power button for 3 seconds to unlock the taillight. OUTPUT / RUNTIME *The taillight modes are subject to the identification display of the bike computer's Light Mode control interface. Due to the different computer brands you use, here may be slightly different. *All data are measured in accordance with ANSI/NEMA FL 1-2009. The test was conducted at a temperature of 25°C and a wind speed of 25 km/h. The runtime may vary depending on external temperature and ventilation conditions, and these deviations may affect the result of testing. 14.5h 8h 11.9h 16.2h 32.7h 19.5h 26.5h 38.4h NIGHT FLASH DAY FLASH ECO FLASH LOW LUMENS LUMENS HIGH 0-100LM 24h 100h 0-3-3-10LM 10-50LM 15LM 50LM 20.1h 26.3h 54h / ONLY RADAR MODE GROUP RIDE MODE 1LM 5LM RADAR ON RADAR OFF NIGHT FLASH HIGH LOW ECO FLASH DAY FLASH GROUP RIDE Light up in the last selected radar flash mode RADAR FLASH MODE RADAR NIGHT FLASH RADAR DAY FLASH 0-300LM 0-60LM RADAR FLASH OFF 0-300LM ONLY RADAR MODE MODE With a connected bike computer, enter "Light Mode" and select the corresponding brightness level.
