Accessing a SMART projectors service menu to reset the lamp timer.
Using the little black remote (part#03-00131-20) press the following Arrow Keys in this order (this may take several attempts): Down, Up, Up, Left, Up
This will display the service menu. In the service menu scroll down to "Lamp Timer Reset" and select ok. This resets the projectors internal lamp timer.
Keep in mind this does not mean your lamp has that many hours, it's only a timer of operating hours of the projector. So, if you change the lamp with a new one and the lamp timer is not reset the lamp timer will no longer be an accurate representation of the actual lamp hours. This is why it's important to reset the lamp timer every time you change a lamp in a projector.
