Resetting the Burner Hour Counter

1. Press the center section @ of the reset switch ² on the front panel to

reset the counter reading to "000.0".

}The hour counter shows elapsed time in hours. The service life of a

mercury burner is 300 hours. For safety's sake, replace the burner when

the hour counter reads "300.0".

1. The service life of the mercury burner is 300 hours. In order not to

impair the safety of the equipment, replace the burner when it has

been used for 300 hours (USH-103OL, HBO103W/2). The burner

may crack if used beyond the specified life time.

When the end of the burner's service life is near, flickering is likely

to increase. It is therefore recommended to replace the burner

according to the purpose of observation.

* This value assumes light cycles composed of 2 hours of lighting

and 30 minutes of extinction (with the USH-103OL). Do not turn it

on and off at a shorter cycle than the above, for this will shorten the

service life of the burner.

2. Before replacing the burner, wait at least 10 minutes, or until the

burner and lamp housing have cooled down, after turning the burner

off. Before removing the burner, confirm that the main switch is "

(OFF) and unplug the connecting cord from the output connector

of the power supply.

Refer to page 16 for details on replacement procedure.

3. After replacing the burner, reset the hour counter to "000.0" as out-

lined above.
