Press the lock of the battery holder to the centre of the housing and pull out the battery holder
like a drawer. Insert the battery. The battery is correct if the positive pole points to the housing
base of the remote control. Slide the battery holder back into the remote until it clicks into
place.
When shipping, the battery is already installed in the remote and protected against discharge
by a transparent plastic foil. Remove the plastic foil prior to first use.
