2. While lightly pressing down on the projection on the upper part of the back-
light connector, pull the connector toward you to remove it from the NT620C
body. While doing this, be careful not to put excessive strain on the backlight
cord.
3. Remove the screws that secure the backlight with a Philips head screwdriv-
er, grip the handle, and pull the backlight out (note that the screws are de-
signed not to come out of the backlight). As shown in the figure below, the
backlight can be removed easily if it is pulled straight out to begin with and
then at a downward angle.

4. Insert the new backlight. Reversing the action in step 3, push the backlight in
at an angle to start with, then, when it contacts something solid, continue by
pushing it in straight. Now make sure that the positions of the screws that
secure the backlight coincide with the positions of the screw holes in the top
of the NT620C PCB.
The backlight has been inserted correctly if it fits snugly in the gap above the
PCB inside the NT620C.
5. After inserting the backlight, secure it well by replacing the screws with a Phil-
ips head screwdriver.
6. Engage the backlight connector with the NT620C connector, ensuring that
the projection on the backlight connector is uppermost. Insert it fully home
and then check that it will not come out if pulled lightly.
