Access codes overview

Access codes consist of the PIN code, PIN2 code, security
code, and module code if using the optional analog module.
Use 0HQX 4 2 5 to change access codes. Avoid using access
codes that are similar to emergency numbers, such as 911,
to prevent accidental dialing of the emergency number.
Note: You can't change the PIN code unless SIM card
security (see page 61) is on.
