MPK Test
This diagnostic requires the panel be disconnected from the MPK data cable.
This test allows the factory to test the MPK connection on the control panel.
Illumination Adjustment
This option allows the user to change the “Low” and “Medium” levels of green button illumination, the “Low” and “Medium”
levels of red button illumination, and the level of LED (display character) illumination. The “High” button levels are not ad-
justable.
The “Low” green level is used for normal button lighting. “High” green and “high” red are also used, but these are not adjust-
able.
Note: The amber color, which is used for output buttons, is created by combining Low green and Low red.
For each setting, use the LEVEL button to increase brightness and PRESET to decrease. Press TAKE to save the setting and
advance to the next color. Press CLEAR to exit.
Burn In
This test rotates through the button lamp and Display tests continually. Press CLEAR to cancel.
Keyboard Test

ing CLEAR twice exits.
Display Test
This test cycles through and displays all legal characters. The test will stop after one cycle. Pressing CLEAR exits. (On the
CP 3810, press the CLEAR button twice to exit.)
