Resetting Factory Defaults

Should the part number (not revision) of the replacement firmware be different from the firmware being
replaced, then the factory default procedure(s) must be performed as detailed below. This will initialize the
CPU's NVRAM and flash memory as required by the new software and sets the data to its factory-configured
state. Note that there are separate procedures for the console CPU and for the generator CPU.
CONSOLE CPU FACTORY DEFAULTS:
The procedure for loading console defaults is described in chapter 3C. Refer to LOAD CONSOLE DEFAULTS.
This is described in the section UTILITY MENU, under CONSOLE.
GENERATOR CPU FACTORY DEFAULTS:
1. Switch the generator OFF at the console, and disconnect the mains voltage.
2. Remove the generator cover as described in chapter 2.
3. Locate S3 on the generator control board. Refer to the appropriate figure in chapter 1, in the section
GENERATOR LAYOUT AND MAJOR COMPONENTS.
4. Set S3-1 to the LOAD DEFAULTS (ON) position.
5. Switch ON the generator. After a brief period, the console will pause at the message FACTORY
DEFAULTS.
6. Switch OFF the generator. Reset S3-1 back to the NORMAL (OFF) position.
7. Perform tube auto calibration as per Tube mA Auto Calibration in chapter 2 of this manual.
Note:
This will initialize all generator data to the factory defaults [tube selection, generator limits (including anode
boost time), receptor setup, I/O configuration, AEC setup, AEC calibration, tube calibration, time & date, error
log, statistics and anode heat units].
NOTE: IF THE FACTORY DEFAULTS HAVE BEEN SET, CRITICAL PARAMETERS (I.E ANODE BOOST
TIME, ETC) MUST BE MANUALLY REPROGRAMMED BEFORE OPERATING THE GENERATOR.
Use and disclosure is subject to the restrictions on the title page of this CPI document.

Tube calibration sequence must be completed in full. If tube calibration is interrupted, the
resulting mA / mAs values will be uncalibrated due to invalid calibration data.
