Changing of Frequencies
The frequency can be converted to either 50 or 60 cps to
suit that of the locale in which the projector is to be
used. The film will advance properly only when the fre­
quency Is adjusted correctly. Changing of frequency can
be done as follows:
1 Open the side cover by inserting a coin into the
* groove of the side cover lock and turning it counter­
clockwise.
О If the projector is used at the locale of 50 cps, the
^ supply belt should be around the larger pulley. If it
is around the smaller pulley the frequency is set at 60 cps.
Move the belt with your hand or a screwdriver if fre­
quency conversion is necessary.
3 Set the frequency conversion plug so that the figure of
the frequency to be used comes on top. For example,
if the projector is to be used in 50 cps, set the plug
into the socket showing the figure 50 on top.
Replacing of the Fuse
Check the fuse when the motor does not move after the
power is switched on. Replace with the 3-ampere fuse by
removing the fuse box inside the projector. In replacing
the fuse, first disconnect the electric cord from the power
supply.
