Freeway 3414/3414R Hardware Maintenance Guide
1.1 Maintenance Philosophy
The Freeway 3414 is designed to be repaired in the field, in a repair depot, or at Proto-
gate’s manufacturing facility. A qualified technician must perform all repairs because
many of the devices inside the Freeway are sensitive to static; also, removing or insert-
ing a printed circuit board must be done very carefully to prevent damage to the con-
nectors and avoid causing incorrect power distribution due to a misaligned board.
