LCD Screen Adjustment
The first items are adjustments to the
Liquid Crystal Display, allowing the
installer or user to tailor the contrast
and backlight intensity to suit the cockpit conditions.
There are two modes: LCD Brightness & LCD Contrast.
LCD will vary in real time while adjustments are made. LED bar & numeric
indication will vary.
Adjusting either the Brightness or
Contrast level requires selecting ei-
ther of the two smaller buttons and
then turning the inner knob. Counter
clockwise to lower the number (level
of Brightness & Contrast) and clock-
wise to increase the number (level of
Brightness & Contrast).
To change the display:
Press the line select for the desired item
Turn the small, inner knob to change the contrast or brightness as
desired.
Cycle the PMA450 power to exit setup screen.
Display Timeout
This is a feature that allows the user to adjust how quickly the screen menus
timeout (revert to main menu).
This allows adjustment of the timeout screen and can be configured from 1
second to 30 seconds by turning the inner knob.
For a user who is unfamiliar with the product, this will give them enough
time to learn the system. After becoming more familiar the user can speed up
the menu screen timeout as desired.
Cycle the PMA450 power to exit setup screen.
Rename “Switched” Inputs
The system is factory set to default as ADF, DME & AUX as shown.
