Keypad Functions
ON/OFF Key
The ON/OFF key, represented by the standard ON/OFF symbol,
turns the M130 ON or OFF (note: the ON/OFF key must be held until the
display turns on or off). Upon power on, the M130 will perform a self-test,
displaying the Meriam product ID, and all segments for approximately 1-2
seconds, then go into the mode in use when unit was powered off. The
firmware version is displayed at the end of the self-test.
BACKLIGHT Key
The BACKLIGHT key, represented by the standard light-bulb
symbol, turns the green display backlight on and off. The backlight will
remain on for approximately 20 seconds if not manually turned off. To
override the auto shut off timer, press and hold the BACKLIGHT key to turn
the backlight on. After holding the key for approximately 2 seconds, the
backlight will flash off and back on. Release the key now and the backlight
will remain on until manually turned off or until power is cycled.
SETUP Key
The SETUP key enters or exits the setup mode and is also used to go
back one menu level. The SETUP icon is displayed while in the setup mode.
Setup menus are shown in the bottom (alpha-numeric) row of the LCD. The
SETUP key also ends simulation activities.
