5.2 Lamp Replacement
Key in the date of replacement in the format of month-
day-year. For instance, if the lamp is replaced on
March 1, 2010, key in the date as shown below.
[3] → [ENT] → [1] → [ENT] → [2][0][1][0] → [ENT]
Thus, the date of lamp replacement is stored in
memory. At the same time, the cumulative turn-on
time of the Hg lamp is cleared to zero (0), and the turn-
on count is reset to 1.
NOTE: The logbook data is reset when the numeric value
of the year and [ENT] are keyed in. Therefore,
even if the same year as that of replacement is
indicated, the year must be numerically input
followed by pressing the [ENT] key.
