Changes and modifications
The FCC rule at 47 CFR 15.21 says the manual "shall caution the user that changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment."
Which manuals
The rule covers "The users manual or instruction manual for an intentional or unintentional radiator."
Manuals online
If the manual is provided "only in a form other than paper, such as on a computer disk or over the Internet," the rule says the caution "may be included in the manual in that alternative form, provided the user can reasonably be expected to have the capability to access information in that form."
What the caution is not
An FCC statement on a device is not a statement about its security.
This is general information, not legal or security advice.

FAQ
General information only. No keypad, lock, or code can guarantee that a door will stay secure or that a break-in will not happen. Keep codes private, change any code you have shared, and follow the maker's instructions. Before you put a keypad or lock on a door people use to leave a building, check with your local building or fire official. In an emergency, call 911.
