
Press  or  to see details of which wards are about to set.

Press  to allow the setting event to proceed.

Press  to defer setting for 30 minutes. Note that the user must belong
to the ward(s) that is due to be set.

Press the Menu key to gain access to the setting menu to set another
ward that is not involved in the current setting event. Note that if the
user is allocated to a single ward then that ward may start setting
immediately.
If the calendar set warning timer has been deferred by a user, the control
unit halts the warning timer, and defers any consequent setting event for 30
minutes. At the programmed warning time the control unit starts counting
down the warning timer again. Users can defer a calendar set in this way a
total of three times. After the third deferral the control unit will set the
system.
Note that deferring setting does NOT defer any unsetting events.
If There Is a Setting Fault. If there is a fault that would normally prevent
the system from setting then a calendar set event will also fail. Ten minutes
before the time for a setting event the control unit will start the calendar set
warning tone as usual, but at the setting time the control unit will not set the
system. The control unit will log the failure as "set fail".
Unsetting Events. When the control unit reaches the time programmed for
an unsetting event the control unit unsets all wards programmed to unset.
There are no specific warning indications for wards unset by a calendar
event.
Manual Setting/Unsetting and Calendar Sets. If a user sets a ward that
is due to be set by a Calendar event, then the ward remains set when the
calendar event time is past. Likewise, if a user unsets a ward before a
calendar event is due to unset the ward then the ward remains unset.
Manually setting and unsetting wards controlled by Calendar Sets will not
alter the times programmed in Calendar events.
Restrictions on Calendar Sets
Please remember the following points when setting up events:
1. You cannot program an event to change the system/ward directly from
one part set level to another. You must program an event to unset the
system/ward first, and another event to set the system/ward to a different
part set level. For example, if event A part sets the system (or a ward) then
you cannot program event B to full set the system. You must program
event B to unset the system and then use event C to full set the system.
