55M4300CCE00 Rev A
To delete a number, change it to “00000” which is not a valid id number.
Note:
It is recommended that the default value of “99999” is retained and new entries
made from position 2 onward but if the default value is changed remember to safely
record the new value. The i4300 system must have a valid number entered before it will
go to the normal working screen if password protection is set to ON.
