Thermal Fuses—Your

Projector is equipped with two ther­
mal fuses to prevent overheating. If
the AudioViewer/Projector gets too
hot, the fuse on the motor will open
and power to the AudioViewer/Pro­
jector will be shut off. When the
AudioViewer/Projector cools, the fuse
will reset automatically and power
will be restored. If the second fuse
(located near the lamp-mounting
bracket) opens, it will not reset. Call a
KODAK Equipment Service Center
to have it replaced and the Audio­
Viewer/Projector repaired (if neces­
sary). Be sure to correct the cause of
overheating before using the Audio­
Viewer/Projector again.
NOTE; The KODAK EC Auto­
matic Timer and the KODAK
EC Sound-Slide Synchronizer
