Reset Pushbutton
You can use the reset button if you forget the password for connecting the
programming software. The pushbutton is accessible through a small round hole at
the top of the housing, approximately 4 to 5 cm (1.6 to 2.0 in.) from the left rim and
recessed approximately 9.5 mm (0.375 in.).
To reset, press and hold the pushbutton for 20 seconds while rebooting the device
by cycling power. Pressing the Reset pushbutton during operation has no affect.
With activation of the reset button:
• All accounts are deleted except for the default account.
• IP address and system ID (SRS) are set to default values.
At the next power cycle, these settings will be restored to the last values stored into
Flash. This means that either:
• the settings prior to the reset will be restored, or
• if any settings were changed after the reset, these new settings will still be in
effect.
