WARNING: Failure to comply with these instructions may void the warranty.
3. Procedure Summary
All system settings and configuration settings are returned to factory default values after this upgrade. You may choose to
manually record your system settings and configuration values prior to performing this upgrade, and then re-configure
those settings afterwards. After the upgrade you MUST (at a minimum):
• Reconfigure the infrared (IR) bench emitter power setting
• Reconfigure the DigiPot setting.
After completing these steps, you may then choose to optionally reconfigure any other settings that you recorded earlier.
Note that you may need to refer to the PAGM Instruction Manual originally shipped with your unit for additional detailed
information (e.g., configuring the IR bench’s emitter power and adjusting the DigiPot). If you no longer have the manual
that shipped with your device, the standard PAGM manual may be downloaded from the Bacharach website at
www.mybacharach.com
. If you have any questions, you may contact Bacharach’s Customer Service Department.
NOTE: Before you begin the microprocessor replacement process, be sure to manually record the values of
any settings you wish to save, as all configured settings will be returned to their factory default values after
the board is replaced. After the microprocessor module is replaced, you may reconfigure these settings.
