GENERAL INFORMATION
This chapter contains operation, maintenance, safety, and service information on the 1145-2 Laser Transmit-
ter and 1275 Laser Receiver. The 1275 Laser Receiver is a portable, battery-operated device that locates the
elevation of a rotating laser beam. Hand-held or rod-mounted, the 1275 Laser Receiver indicates its position
via a nine-channel LCD or with synchronous audible tones. The 1145-2 Laser Transmitter is used with the
1275 Laser Receiver.
