Single Line Analog Phone: - Compatible with all hotel/motel PBX systems.

Largest Customizable Faceplate:Ample room to create a faceplate which best fits the ambiance of the room and provides important information to the guest.

10 Programmable Guest Service Buttons: Provides the guest with a wide selection of available services accessible with the single touch of a key. This eliminates the need to read through phone books, hotel information packets or, more importantly, wait for a hotel concierge or staff member to provide information.

"Euro" or Standard "K" Handsets:Select one of two different handsets, whichever fits the room decor. Both are hearing aid compatible and are compliant with the Hearing Aid Compatibility (HAC) act of 1988.

Volume Control:A two step volume control function provides just the right amount of control to accommodate difficult hearing situations. The volume increase levels meet the requirements established in the 1995 amendments to the HAC act.

Proprietary Message Waiting Circuitry:Patent pending design allows this phone to reliably support five or more Message Waiting phones on a single line.

Memory Backup: No need to fumble with installing a battery. The Diamond +10’s efficient design will retain the memory settings for virtually the life of the phone.

Easy Access Data Port:Guests do not have to unplug the phone or use an awkward line splitter when they want to use their laptop computer. They can simply plug their computer modem directly into the side of the Diamond phone and they’re ready to go.

Desk or Wall Mount: For those areas where counter space is at a premium, the Diamond +10 can easily be wall mounted in a convenient location.
