Standby mode

Active mode

Push-to-talk mode

(NetLink i640 Wireless Telephone only)

The handset uses different amounts of power and bandwidth in different modes of operation. Bandwidth is provided by access points located throughout your facility. Bandwidth availability varies by type of access point. The Battery Pack in your handset provides about four hours of talk time or 80 hours in the Standby mode (see below).

If push-to-talk (NetLink i640 Wireless Telephone only) is allowed in the Admin menu and enabled by the user, standby Battery Pack life is decreased to about 30 hours.

Conservation of battery life and bandwidth is possible when you understand the modes and use them appropriately.

In the standby mode the handset is waiting for an incoming call or for the user to place an outgoing call. The extension number is shown on the display and there is no dial tone. In this mode, the handset is conserving battery power and bandwidth.

You may set certain preferences in the user option menu described later. This menu is accessed from the standby mode.

It is important to return to the standby mode after finishing a call by pressing the EndTCallT key. Unless otherwise directed, the following instructions for using the handset assume that it is in Standby mode.

To place a call, press the StartTCallT key. This transitions the handset to active off-hook mode. There is a dial tone, the handset is in communication with the PBX, and the display shows information as it is received from the PBX.

The handset is also in the active mode when you receive a call.

In certain PBX integrations, some features are designed to be accessed from an active on-hook mode. To go on-hook while still

active, you may be directed to press the LineTT key or a Release feature key.

See the Appendices for information about on-hook dialing (cell phone dialing).

Whenever you are in active mode, whether off-hook or not, the handset requires the most bandwidth of any mode.

To conserve bandwidth and battery power, when you have completed a call or are finished accessing active mode menus and features, press the EndTCallT key to exit the active mode and return to the standby mode.

The push-to-talk mode utilizes a common channel for incoming and outgoing radio communication. Outgoing communication uses the same amount of bandwidth as the off-hook mode. Incoming communication uses about half as much.
