The machine is initially set to Normal, which lets the machine connect to a standard PSTN (Public Switched Telephone Network) 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. The feature works when Tel/R is pressed.
Note
| | You can program a Tel/R key press as part of a number stored in a Speed Dial location. When programming the Speed Dial number press Tel/R first (the screen displays “!”), then enter the telephone number. If you do this, you do not need to press Tel/R each time before you dial using a Speed Dial location. (See Storing Speed Dial numbers.) However, if PBX is not chosen in the Telephone Line Type setting, you cannot use the Speed Dial number that Tel/R press is programmed into. |
