Change UV Lamp Life

In this screen, you can set the number of operating hours before receiving the
replace UV lamp warning. For most UV lamps, the output of UV light
decreases at a constant rate. Typically, after 6,000 hours of operation the
lamp will output 80% of the UV light it did when it was new. This option
allows you to set operational life of the UV lamp, in 100 hour increments.

From the UV Settings menu screen, use the

and

buttons on the touchpad to highlight the

Set UV Life

option-it will turn white when selected. Press

OK

to

enter the Set UV life screen. Use the

and

buttons

to increase or decrease the lamp life in 100 hour
increments, until the desired value is displayed, and then
press

OK

. The screen will then return to the UV

Settings screen.
