If you cannot edit or delete an individual (one-touch) key or group key...
• If the individual key or group key that you are attempting to edit or delete is being used in a reserved transmission
(including a timer transmission) or a transmission in progress, wait until the transmission is finished or cancel the
transmission.
• If the individual or group key that you are attempting to edit or delete is included in a group key (in the case of an individual
key) or a program, delete the key from the group or program and then edit or delete the key.
• If your administrator has enabled "Default Address Setting" (on the machine) or "Inbound Routing Settings" (in the Web
pages), editing and deleting will not be possible. Remove the destinations that are preventing editing/deleting, and then
edit or delete the key.
