Mania EFX fixtures use a slow-blow fuse for protection against current
overload. An indication that the fuse may have blown is that when power
is applied and the lamp is switched on, no light is produced.
If the fuse blows repeatedly, there is probably a fault. Disconnect the
fixture from power and data and contact a Martin service technician.
Never bypass the fuse or replace it with one of another type or rating.
To replace the main fuse:
1. Disconnect the power cable.
2. Pry open the fuse holder next to the
power cable inlet with a flat-head
screwdriver and remove the fuse.
3. Replace the fuse with one of the
same type and rating. Fuse ratings
are listed on serial number labels and
under "Electrical" on page 49.
4. Replace the fuse holder before
reapplying power.
