 Introduction

Feature keys give you access to system features such as Hold, 
Transfer, Mailbox, and Program. Press the key labeled with the feature 
name to gain access to the feature. You can also dial feature access 
codes to gain access to features. (See “Feature Access Codes” on page 
1-15.)

The labels used in this guide to indicate feature names on keys 
are the defaults that come with your system. However, your 
system administrator can configure them differently to suit 
your company’s requirements.

Some of the telephones in your system may be set up to use one class 
of service (the primary) during normal business hours and then 
automatically change to a more limited one (the secondary) during 
non-business hours. If so, the features you can use may vary, 
depending on the class of service in effect at the time.

A personal identification number (PIN) enables you to use another 
telephone within your company to gain access to the features of your 
own telephone. You may also need a PIN to be able to dial an outside 
number.

Ask your system administrator whether you have been assigned a PIN. 
Also see “External Calls” on page 2-8, “PIN Authorization Features” 
on page 7-12, and “Forced Authorization” on page 7-15.

Callback Key: The Callback key can help you complete calls to 
extensions that are busy, ringing, or in Do Not Disturb mode. (See 
“Callback Request” on page 3-5 for more information.) It also lets you 
return calls to parties that have left you reminder messages and to the
