Security Access Code: Enter a security code of four digits that will be used
when polling the phone. This code is programmed into the phone the first time
it reports or is polled, and is required in future polls. To change the code,
enter a new code into this field. The next time the phone is polled, the old
code will be used to initiate communication, then the new code will be programmed
into the phone. To disable the use of this code, enter four zeroes in the
field.
