Entering programming mode
The Engineering Access code is required to allow the detector parameters to be
programmed. The access code is only valid whilst the user is in programming
mode. It will need to be entered again if programming mode is exited, if the
detector is powered down, or if <RESET> is pressed.
You must re-enter the access code if you:
• Exit Programming Mode
• Power down the detector
• Press the <RESET> key
To enter Programming Mode, press one of the following program menu keys:
• <Menu>
• Right or Left Arrow
• <Enter>
The detector responds by prompting the user for the Engineering Access Code
as follows:
Access code: 0000

To enter the default access code, enter the following sequence:
