3.13 Error Reporting

The dome constantly monitors its own health and is able to indicate that a problem has occurred by
a flashing square in the top right hand corner of the transmitted picture. The cause can
subsequently be requested when convenient. Alternatively, the unit can display the error text
instead of the flashing square.

3.14 Activity light

A green LED provides some diagnostic help when first switching the dome on and also indicates
when command signals are received. As it may be visible externally it can be switched on or off.

3.15 User Timeout

There is a possibility that the dome may be left pointing at an unhelpful scene and, for whatever
reason, 'forgotten'. To cater for this eventuality, two settings have the specific function of acting to
prevent this happening. These are Preset 001 and Tour 001.
A time delay can be set between 1 and 999 seconds and a default response to the timeout being
reached also defined. If the time is exceeded after any joystick/key entry Pan and Tilt input at the
Control Panel then the default action will occur.
If a delay time of 0 is set, no default action will occur and the unit will wait indefinitely for the next
user input.
If a dome menu screen is left waiting for an input for more than 3 minutes then the system times
out and the dome resumes its previous activity.

3.16 Set Video Amplification

This facility allows the video gain to be adjusted from the normal setting, with four levels available.
Video lift can be tuned on or off and is normally set to the Off position.

3.17 Privacy mode

It is sometimes desirable to prevent operators from viewing certain areas. To meet this requirement
the Privacy mode allows black patches to be set up to cover these areas.
The size of the patch overlaid is the size of the monitor view at whatever zoom setting is used.
When zooming out, the patch reduces in size so that it only covers the original area.
