6.9.3 Incorrect Code Lockout / Communication Mode Switch Delay
The RFC-1 disconnects when an incorrect security code is given. This is a security measure to stop an intruder from
making repeated attempts at guessing a code. The RFC-1 will ignore incoming calls for a short time period after a
code fails. This feature can be used to thwart attempts to guess the RFC-1 security code.
The duration of time that calls are ignored is adjustable. The factory setting is short enough so that an authorized
user should not have a problem contacting the system if a code is entered incorrectly. The time period can be made
longer should the need arise. This lockout period only applies to calls, not connection through the local phone.
Select a lockout time from the table below and program the value from column V1 at memory address 1016 to adjust
the security code lockout time.

mode to data mode. See communication mode programming for more details.
