Nikon DIAPHOT 300 - Operations on Components; ON;OFF Switching of Power. 1

IV. OPERATIONS ON COMPONENTS
1. ON/OFF switching of power
NOTE
• Before turning the power on, make sure that the input voltage
to the power supply unit corresponds to the available line
voltage.
• The microscope uses a 12V, 100W halogen lamp bulb as the
standard light source. Do not use any other lamps. (See
page 53.) If a lamp bulb of over-rated wattage is used, the
light intensity adjusting circuit may be damaged.
• -CAUTION - Do not touch the lamphouse or place any
heat-sensitive object near it, since the lamphouse becomes
extremely hot during use. Also use great care not to bring
volatile substances (such as gasoline, thinner, alcohol, etc.)
close to the lamphouse. Such exposure may result in
inflammation or other dangers.

Connect the power supply unit and lamphouse with the lamphouse cable.
To turn the power on, turn the power switch on the power supply unit front panel to
the "1" position. The lamp goes on. (At this time, the pilot lamp on the power
supply unit front panel also goes on.)
To turn the power off, turn the power switch to the ”0" position. The lamp goes
out. (The pilot lamp on the power supply unit also goes out.)
