The D704’s 10 clear melodies and amplified ring tones ensure you will never miss a call. You can amplify incoming sound up to 40 decibels, to make speaking with callers clear and easy. The phone’s four tone control settings let you adjust the pitch of a caller’s voice through both the handset and the high-performance speakerphone.
An easy-to-read caller ID display shows you who is calling. Ten one-touch programmable memory buttons let you call your loved ones quickly and easily. And you can add up to five expandable handsets (D704HS), which connect wirelessly to the base unit.
