Note: If the lens, CCD and board in item 12-15, it is neces-
sary to adjust again. Item 12-15 adjustments other than
these should be carried out in sequence. For 14 and
15, carry out adjustment after sufficient charging has
taken place. In case of carrying out adjustment item 12
and 13 after adjusting item 14 and 15, adjust item 12

4. Color Viewer
1. Turn on the switch and wait for 30 minutes for aging to take
place before using Color Pure.
2. The luminance adjustment control on the color viewer
should be set to around the middle position (memory 5)
during use.
3. The fluorescent lamps which are used in the color viewer
are consumable parts. After the cumulative usage time
reaches 2000 hours, the color temperature will start to increase as the usage time increases, and correct adjustment will not be possible. When the cumulative usage time
reaches 2000 hours, all of the fluorescent lamps should be
simultaneously replaced with new lamps.
