Option Authorization File (OAF)

Topcon Positioning Systems issues an Option Authorization File
(OAF) to enable the specific options that customers purchase. An
Option Authorization File allows customers to customize and
configure the a receiver according to particular needs, thus only
purchasing those options needed.
Typically, all receivers ship with a temporary OAF that allows the
receiver to be used for a predetermined period of time. When the
receiver is purchased, a new OAF activates desired, purchased
options permanently. Receiver options remain intact when clearing
the NVRAM or resetting the receiver.
The OAF enables the following kinds of functions. For a complete
list of available options and details, visit the TPS website
(www.topcongps.com/tech/index) or consult your TPS dealer.
