5.3.4.1 Checking the battery 
WARNING
!
Risk of fire and explosion due to faulty battery
The safety electronics on damaged or faulty batteries 
may fail. The residual voltage can cause a short 
circuit. The batteries may self-ignite and explode.
The battery needs to be checked before it is charged 
for the first time.
 Press the On-Off button (battery).
 If none of the LEDs on the operating and charge 
status indicator light up, the battery may be 
damaged.
 The battery can be charged if at least one of the 
LEDs on the operating and charge status indicator 
is fully lit up, but not if all of them are.
 Once the battery has been charged, insert the 
battery on the bicycle.
 Never charge a defective battery.
