Safety Precautions
Safety Precautions
T o prevent damage to the equipment and operating
personnel, please observe the following precautions:
Make sure that the voltage source contains a satisfactory
path to ground.
Do not operate the unit where fluids can come into
contact with the electrical components.
When changing the bulb:
• Disconnect the electrical supply.
• Allow the unit to cool.
• Use a 4 watt fluorescent lamp, which you can purchase
from your authorized Navitar dealer .
There are no user serviceable components (other than
changing the lamp). Opening the unit will expose
dangerous voltage levels and sensitive electronic
components. A qualified technician should perform all
repairs.
T o prevent the unit from damaging condensation and
thermal shock, certain procedures must be followed:
• In cold weather, always put the unit in a moisture proof
container or enclosure before transporting.
• Either keep the unit warm during transportation, or allow
sufficient time for it to warm up at the destination. Keep
the unit in the original moisture proof package while it
warms up. (The goal is to prevent warm, moist air from
striking the cold electronic and optical components,
which will cause damaging condensation.)

not touch the lamp during operation or when collapsing
the arm.
• Clean the lens and LCD monitor screen with an air
spray or soft dry cloth.
