After removing the battery pack from the unit, secure it in the
connected charger.
To do this, turn it upside down and slide it along the guides at the top
of the charger until it clicks into place - see the following picture:
When the red light on the side of the charger illuminates, charging of
the battery has begun.
When the light turns green the battery is fully charged.
You can then remove it (by pressing the button on it and pulling it
out towards the button) and reattach it to the unit - sliding it in until
you hear a "click".
Note: If you do not use the unit for more than 3 months, it is
recommended to periodically connect it to the charger to fully charge
it.
This will have a positive effect on the battery life.
