The machine's [Phone Line Set] default setting is [Normal], which lets the machine connect to a standard Public Switched Telephone Network (PSTN) line. However, many offices use a central telephone system or Private Branch Exchange (PBX). Your machine can be connected to most types of PBX. The machine's recall feature supports timed break recall only (TBR). TBR will work with most PBX systems allowing you to gain access to an outside line, or transfer calls to another extension. To use this feature, press the button in the table.

Program a press of the button in the table as part of a number stored in the Address Book (One Touch Dial and Speed Dial in some models). When programming the Address Book number (One Touch Dial number and Speed Dial number in some models), press the button first (the LCD displays ‘!’), then enter the telephone number. This avoids having to press the button each time before you dial from the Address Book (One Touch Dial or Speed Dial). Your Telephone Line Type must be set to PBX on the machine to use this programming.
