Electronic Alarms and Home Security Devices - Help with Ademco Via 30

I'm new to this forum and wanted to see if someone could help me with a problem. We did some remodeling and closed in a bathroom window. My keypad beeps and displays "check 18 bath window", but the wireless transmitter has been lost somewhere in the house. I would like to delete it from the system, but don't know how. I have the installer and master codes. Can someone give me instructions on how to do this? Thanks.

In *56 programming change the zone type to 00, it will offer a prompt to delete the zone.

I hate to show my ignorance, but I don't know how to get to that point. What steps do I follow to get there? Thanks.

Go to program [installer code] + 8 + 0
enter *56
Prompt: Set to confirm? Enter 0 for no
Prompt: Enter Zone number. Enter the zone number and press *
Prompt: It will display a summary of the current zone settings. Press *
Prompt: Zone Type. Enter 00 when it displays "delete zone" press *.
From that point simply press * until you get back to ther zone number prompt. There, enter 00, then enter *99.
