HOW TO USE：

Taillight switch：
Lightly touch the taillight switch in OFF state: turn on the device, then lightly touch the switch again to cycle through five modes: constant -> strobe ->slow strobe ->breathing flash -> warning flash;
If the power on status exceeds 5 seconds and the taillight switch is lightly touched, it will shut down;
Long press the tail light switch in the power on state: turn off;

Radar switch:
Tap the radar switch to switch the radar function on and off;

Radar function prompt:
When the radar function is turned on, the light flashes twice;
When the radar function is turned off, the light goes from the brightest to the extinguished;

Note:

1. The tail light function and radar function are independent of each other and can work independently;
2. When the tail light battery is low, the radar function will be automatically turned off to ensure that the tail light can work properly.

Brake sensing function:
Whether the taillight function is turned on or the radar function is turned on, it will automatically enter the brake sensing function;
When a brake action is detected on the bicycle, the taillights will be highlighted for 3 seconds to alert pedestrians or vehicles behind;

Radar function:
When a vehicle is detected behind or entering the monitoring distance, the taillights will be highlighted for reminder, and the buzzer will emit a “beep” sound to alert the user;
When a vehicle is detected behind or entering a distance of 10 meters, the taillights will flash to remind the user, and the buzzer will emit two beeps to alert the user;

How to turn on/off the buzzer:
Double click the radar switch: turn on/off the buzzer.
When the buzzer is turned on, it emits two beep sounds;
When the buzzer is turned off, it emits one beep sound.

Regarding automatic sleep mode:
When the product does not sense movement within 30s, it will automatically enter sleep mode, and the tail light function and radar function will be turned off. When vibration is detected, it will automatically exit sleep mode and return to the pre sleep state.
