Philips SE6591B/17 1.9 GHz DECT 6.0 cordless phone

Single-handset DECT phone for dual-line homes

The Philips SE6591B/17 is a 1.9 GHz DECT 6.0 cordless phone with an integrated digital answering machine. It ships with one handset and supports expansion up to eight handsets. The base station handles two separate lines, making it suitable for households or small offices that manage personal and work calls on one device.

Check your line service and handset needs

Verify that your telephone provider delivers two active lines to the wall jack before relying on the dual-line feature. If you plan to place handsets in multiple rooms, confirm the number of additional units you want; the system supports up to eight total. The base requires a mains outlet for power and a connection to the telephone socket.

Low-power base with handset talk-time limits

The base station draws minimal continuous power while idle and charges the handset when docked. Handset battery life determines talk and standby duration; the handset includes a backlit amber keypad and a white-backlit 98x67 CSTN display for visibility in dim conditions. Polyphonic ring tones and adjustable volume let you set audible alerts without excessive loudness.
