Firmware Credit System
The credits system is a flexible way of adding to the recorder features without having to upgrade the firmware. Simply
purchase a number of credits to cover your current and possible future requirements and the recorder will be delivered with
the credits loaded.
Credits can be applied as desired to the Firmware functions until the total number of credits purchased has been used up.
Additional credits can be purchased later if new features are to be activated and not enough credits are available to support
these additional functions.
Firmware options are selected using the Model Selection Guide. Details of each firmware option are listed here.
