2.3 Lockng and unlocking the mechanism
Giotto fixtures have a mechanical locking
system for the moving parts.
Moving head and yoke must be locked
every time the fixture is transported,
using either a suitable flightcase or the
original packaging, which have suitable
shock-resistant support devices.
ALWAYS remember to unlock the mecha-
nism BEFORE switching the fixture on!!!
Locking and unlocking procedure is car-
ried out by turning the two knobs on the
yoke, following the printed instructions.
2.4 Replacing dichroic filters
As well as the CMY mixing system, the Giotto also has a wheel fitted with 5 high quality selected
dichroic filters (ø51.8mm). If operators require to replace these with other colours, once the
cover has been opened (see chapter 2.1) find the
filter wheel, open it extremely carefully, remove
the old filter and fit the replacement.
This procedure must be carried out by qualified
personnel with the fixture switched off and after
waiting at least 30 minutes for the internal parts
of the moving head to cool down.
2.5 Periodic cleaning and checks
The fixture should be cleaned every 300 approximately (or whenever necessary) using compres-
sed air to remove dust which may have built up.
The paint used can be cleaned with alcohol or similar products: in this case, always use a non-
abrasive cloth. Make absolutely certain to avoid damaging the display by pressing too hard on it.
To ensure perfect fixture efficiency, an overall check every 600 running hours is advisable.
Electrical and mechanical parts must be checked by qualified technical personnel.
