C.1 Introduction
For user security, the XGM868i offers two special functions in a separate menu: selection of single- or dual-channel
operation, and the factory-default reset. While the first function enables you to reset the channel configurations set
during manufacturing, the reset function, by restoring the meter to its original state, allows you to purge potential errors
in program memory.
To enter the Factory Test menu, press [Escape], followed in succession by the up arrow key ([]), the right arrow key
([]), the down arrow key ([]), the left arrow key ([]), the up arrow key again (forming a loop around the keypad),
and finally the [Enter] key. The screen displays FACTORY TEST, as shown below.

C.3 Resetting the XGM868i to Factory Defaults

the up and down arrow keys to alter each character until the string is "FRIG" plus the number of channels (that is,
FRIG1 or FRIG2). Press [Enter].
The XGM868i reinitializes with factory default settings, and displays the message, "Review meter settings." Since the
default for the meter display is OFF, you will need to enter the Keypad Program to reset the LCD, as described below.
