The MDW 9000 Wireless Telephone is part of the TransTalk
ily of telephones. This wireless telephone has three basic parts, the handset the charging cradle,
and the radio module.
The handset has line/programmable feature/intercom buttons, Drop, Mute, Hold, Confer-
ence, and Transfer buttons, a Headset On/Off button and a Handset On/Off button, a
LCD display, a Volume control switch, battery charging contacts, a flexible antenna, and
a Headset jack.
The charging cradle has a handset hook, a spare battery cover, a spare battery garage,
and a spare battery charge indicator, and battery charging contacts.
The radio module has Power, Pass, and Radio indicator lights, a top hook, card edge,
and snap lock which connect the radio module to the carrier assembly/backplane, an
antenna, and power plug and line connectors.
In order to provide you with the freedom of mobility, the MDW 9000 is not connected physically
(by a line cord or wire from the handset) to the DEFINITY system. Instead, the MDW 9000 com-
municates by way of a radio link to its matched radio module, which, in turn, connects it to the
DEFINITY system. The telephone needs merely an electrical outlet, and a test check to make
sure that the handset is in range of its matching radio module.
The handset communicates through a matching radio module. When up to six wireless phones
are used within a single location, a carrier assembly is required. When the radio modules are
placed in the carrier assembly, it is considered a radio base station.

Applications

The MDW 9000 Wireless Telephone can be used with the DEFINITY Communication System G1,
G2, G3, System 75, and System 85.
