then rotate the bulb counterclockwise in
order to release it.

Two types of bulbs are in use
The guide lugs on the twin-pole bulb are
at different heights, and it is only possible

turn the bulb gently. Do not use force. If
this does not work, take out the bulb and
turn it half a turn and try again.
