SAFETY PRECAUTIONS
1. The applicable lamp housing is a mercury burner configuration Olympus lamp housing (U-ULH, U-ULS100HG,
U-LH100HG, etc.)
2. The high pressure mercury burner (mercury arc lamp) used should be a USH102D burner (mfd. by Ushio Electric) or
HBO103W/2 burner (mfd. by OSRAM).
The ultraviolet rays emitted by the burner are harmful for the eyes and should not be directly looked at with
unprotected eyes. Consequently, the burner should never be turned ON as long as the lamp housing is not
mounted on the microscope.
3. When the burner hour counter of the power supply unit indicates 200 or 300 hours, turn the main switch to “O" (OFF) and
allow the mercury burner to cool for at least 10 minutes before replacing it.
High-pressure gas is sealed within the mercury burner. Thus, if it is continued to be used past its service life
expectancy, the glass tube may deform and may sometimes rupture.
4. When disposing of the mercury burner, always follow national and local laws and guidelines.
5. The power supply unit contains high-voltage components. Never attempt to modify or disassemble the power supply unit.
6. High voltage is applied to ignite the mercury burner. To prevent any hazards, always turn the main switch on the power
supply unit to “O" (OFF), unplug the power cord plug from the mains outlet and disconnect the mercury burner socket
cord plug from the U-RFL-T and wait for at least 10 minutes before replacing the burner.
7. Never switch the main switch to “I" (ON) while the mercury burner socket connection cord plug is not plugged in.
