Disturb mode or cannot receive any more calls.

Confirmation Tone—Very short beeps followed by dialling tone indicates you have cor-
rectly set or cancelled a system feature.

SYSTEM ACCESS CODES
Your system is configured with default system access codes for using the various features
described in this guide. These codes are also printed at the back of this guide for quick
reference. However, your system may have been set up to use a different set of codes.
Moreover, the availability of some features depends on the type of DCS keyphone system
to which your phone is connected. Therefore, if your phone does not work as described in
this guide, see your system administrator for advice.
A ‘Changed System Access Codes’ table has also been provided at the back of this guide
for you to enter the codes required by your system, if they are different from the default
codes.
