Operating Distance
The distance between the remote control and the exposure head is determined by summing the length of the remote control conduits plus the total length of source guide tubes used, and normally should not exceed 47 ft (14.2 m) with standard 25 ft. controls.
Standard remote controls:
25 ft (7.6 m), 35 ft (10.7 m), 50 ft (15 m)
Standard source guide tubes (projection sheaths):
7 ft (2.1 m) set of three source guide tubes: 21 ft total (6.3 m)
