Keypad Beeper and Display Brightness
The RoadRunner contains a keypad beeper that provides feedback to
the user by emitting a short chirp sound each time a key is pressed. In
some applications, it may be necessary to mute this beep, and this can
be done using the keypad sequence
<Maint><Beeper>
or the MBX command.
The display contrast can also be adjusted over a wide range for ease of
viewing at any angle and under varying lighting conditions. Use the
keypad sequence
<Maint><Contrast>
or the CCV command to adjust the display.
