6.6 Removing a cordless phone
If a cordless phone is no longer used, it is better to prevent misuse and remove
it from the cordless system.
To remove a cordless phone from the cordless system:
1. Cancel the subscription of the cordless phone: use the ‘ Delete
Subscription’ option in the ‘ Cordless phone’ menu.
2. It is recommended to make a new backup of the cordless system data: use
the ‘
System Backup ’ option in the ‘ File ’ menu. Your supplier can restore
this backup in case of serious system troubles.
Note
Do not use the ‘Delete Extension Number’ option to remove a cordless phone.
If an extension number is deleted, the line connection between PABX and
cordless system is terminated. As a result, it is not possible to use that line with
a cordless phone. If somehow an extension number has been deleted, see the
CSM help file to add the extension number(s) again.
6.7 Change system date and time
In some cases it is necessary to change the date and time of the clock on the
DCT1800-S by using the ‘
Change Date/Time’ option in the ‘ System ’ menu.
These date and time are displayed on the cordless phones connected to the
system.
For example, changing date and time is necessary when changing to daylight
saving time and back.
