4. Using the Optiset

E Liberator Phone

Battery Low Indicator

When the battery is running low, the handset generates a visual

warning signal by displaying the Battery Low icon. This icon stays

active until the battery is replaced. While in Talk mode, you have 20

seconds to change the battery without dropping the call.

The handset can provide the user with up to 5 hours of continuous talk

time or 40 hours of continuous standby time (waiting for a call).

Function Keys

The handset provides two rows of function keys. See Figure 1-9,

“Optiset E Liberator Telephone,” on page 1–9.

The upper row contains four keys that can be programmed at the

communications server as line and/or feature keys. Line keys are used

to answer and place calls. Feature keys provide access to the

communications server system features such as Hold, Transfer,

Conference, and Mailbox. You can press the key labeled with the

feature name to gain access to the feature.

Because of the limited number of keys that can be programmed as

feature key on the handset, the OptiGuide menu is the primary user

interface to features.

Note:

Each phone in the system is set up individually at the

communications server to have specific telephone features.

Therefore, you may find that some features described in this

guide are not available on your phone.

The lower row also contains four keys. The first three keys are

guidance keys and are reserved for use with the Siemens OptiGuide

interface. These keys are , , and .The fourth

key is a Mute key which mutes the microphone.
