e) Testing the Rechargeable Battery Charge Condition
The current charge condition of the ight battery can be tested
easily at any time.
For this, briey push the on/off button (1) at the ight battery. For
approx. two seconds, the four LEDs show the current charge
condition.
When the ight battery is discharged, only LED 1 will be lit; if it
is fully charged, all four LEDs will be lit. At a partially discharged
ight battery, e.g., LED 1 and LED 2 would be permanently lit
and LED 3 may ash.
The display of the rechargeable battery voltage above
the four LEDs only serves as a general indication. The
precise battery voltage can be read in operation of the
quadrocopter at the transmitter display if necessary.
