the units’ power sockets.

Lamp fails to switch on
• If this happens immediately after the last time the unit was
switched off, allow a few minutes between switching off and

had time to cool down - seek technical assistance from
your nearest Dealer.
• Check the state of the connection by interpreting the code
displayed by the system LEDs in accordance with Table 1.
