GENTZ is easy to operate.
Place the road bike on a stable stand etc.
Remove the installed endcap.
Insert GENTZ into either left or right side of handlebar.
GENTZ is designed to fit tightly into the handlebar. Please make sure to insert it firmly.
Insert the other non-buzzer endcap that comes with the GENTZ package into the opposite side of handlebar.
After insertion, press on the buzzer to test if it sounds.
The buzzer sound switches to intermittent beeping (buzzer ON: 0.1 seconds / buzzer OFF: 0.05 seconds) when the battery becomes low.
Charge the battery with a USB cable when the sound has switched to intermittent beeping.
