KEYPAD SYSTEM
The AVFM-II has a simple 3-button
calibration system. Operating and
calibration modes are shown on the
16-digit alphanumeric display. The
keypad is used to move around the
menu to calibrate the AVFM-II, and to
view operating mode and functions. A
beep is sounded as each key is pressed.
If the keypad is not used for 2 minutes,
the AVFM-II will automatically go to
RUN
mode (scrolling display). Use the
keypad to explore the Menu and
become familiar with its features.
