Figure 43: Edit Customize Device Settings
Scroll down in the dialog to view and edit the device-specific options. If the users would like to
add more options which are not in the pre-defined list, click on “Add New Field” to add a P value
number and the value to the configuration. The following figure shows setting P value “P1362” to
“en”, which means the display language on the LCD is set to English.
The warning information next to the P value field indicates that the option matching the P value
number exists in the configuration already.
For P value information of different models, please refer to configuration template here
