The CS 3.0 includes many programmable features that enable you to customize its operation. You can change any feature (including factory settings) by using the following programming method:

1) Pick up the telephone and press 
2) Enter the desired changes
3) Press the key (you will hear 3 beeps)
4) Press the key again to exit programming mode
5) Hang up the phone

You have eight (8) seconds between each key entry to enter another command. If you do not enter a command within eight (8) seconds, the CS 3.0 exits the programming mode without saving the changes.

When you are in the programming mode and entering changes, the CS 3.0 notifies you of correct or incorrect entries with the following signals:

· Three Short Beeps: Indicates that the entry is valid, and the CS 3.0 has accepted the change. 

· Single Low Beep: Indicates that the entry is invalid, or out of normal operating range, and the CS 3.0 did not accept the change. Re-enter the command string with a valid entry.

If you do not want to save your changes and you want the system to reset the previously saved settings, press the key. The changes will be deleted as you exit the programming mode. When you are finished with your changes, press the key a second time to save the changes and exit the program mode.
