18. Altering the operating voltage and frequency (Reserved for technical staff only)
If the factory preset operating voltage and frequency do not correspond to those in use in your country of operation, you may alter the settings as described in the following paragraphs. Incorrect selection of operating voltage and frequency will seriously compromise the functioning of the projector.
Opening up the projector
To carry out the following procedures, the projector housing should be open, Instructions for opening up the unit can be found in sections 19 of this manual.
18.1 Selecting the voltage on the autotransfomer
After having opened up the rear of the unit: 1) Locate the autotransformer on the left of the unit.
2) Select a voltage from amongst 100, 115, 208, 230 and 240V by removing cable n° 8 and moving it to the required voltage. To determine which is the correct tap, refer to the sticker located on the autotransformer.
Connections 9, 7 and 15 should not be moved under any circumstances. If in doubt, consult the circuit diagram or refer the unit to specialist trained personnel. 4) If the operating voltage selected is either 100 or 115V, replace the 5 Amps T fuse (which is suitable for 208/230/245 V operation) with one rated at 8 Amps T. The fuseholder is located near the base of the unit. The operation should be reversed should the voltages be reversed.
8AT @115V 5AT @230V 5) Operating frequency may now be set (if necessary) as shown in the next section.
