Several alarm types simultaneously activated
Do not activate the three alarm sensor types simultaneously when short delay and
repeat times are set and the pre-alarm is switched off. This may block the menu access
(to deactivate an alarm type) in case of a simultaneous alarm call. Place the mobile
unit in the charger and keep it placed there. Make your configurations then.
Connections
Internal and External Call Numbers
Internal and external call numbers for reaching you are assigned during configuration
of the Aastra 800 / OpenCom 100 communications system.
External Seizure and Entry of Call Numbers
If you hear the external dialling tone after pressing the call key, your telephone
is set to spontaneous external line seizure. If you hear the internal dialling tone after
pressing the
call key, your telephone is set to manual external line seizure. The
external line seizure applicable for you is configured by your system administrator
upon user group configuration.
If your telephone is set to manual external line seizure, an internal line is seized ini-
tially. You can dial an internal call number immediately. You have to use the external
line prefix to dial external call numbers (default: “0”). The system administrator defines
this code for all users in the Aastra 800 / OpenCom 100 and informs you of the appli-
cable value.
If your telephone is set to spontaneous external line seizure, an external line is seized
initially. You can dial an external call number immediately. To reach internal users –
before entering the internal call number – press the
star key twice.
If you dial a call number for an enquiry or when you programme call number destina-
tions, you have to enter these call numbers in accordance with the external line
seizure applicable to you.
Example
You wish to programme call forwarding.
• You enter an external call number directly with spontaneous line seizure; with
manual line seizure, enter the prefix code for the external line (default: “0”).
Exception: The destination of “Divert MSN” is always entered without a prefix code.
