All cockpit accessory displays and cabin equipment, such as the FD50HMT, should be

The FD50HMT offers excellent versatility for installation in different aircraft. Two mounting
holes are located on the mounting plate of the unit which allow for installation of two #8 x 100
degree flat head screws.
Power
This is a 28VDC product that requires .3 Amps of power.

Frequently Asked Questions
My video was working fine, but now I don’t have any display.
If the pilot lowers the backlight all the way down to the lowest setting (No illumination), the unit
will remember this setting and appear to be inoperative. Simply raise the level of backlighting
to view the display.
Is there a locking mechanism to keep the FD50HMT open?
No, however the tension can be adjusted by tightening the two shoulder screws (one on top,
one on bottom). CAUTION: If screws are loosened, the user must remove screws one at a
time and apply Loctite 680 retaining compound, and re-attach screws.
Top screw shown here
How do I navigate through the menus?
Use the Menu button to open the menu. Use the Select button to choose the applicable
menu page, and press Up to enter the selected menu page. Use the Select button to
scroll through the options, and then use the Up and Down buttons to increase or
decrease the options’ values.
