Welcome

Welcome to the User Guide for the DT288 cordless phone in the Ericsson Enterprise business communication system MD110.

The User Guide describes the facilities of the Ericsson Enterprise communication system and the DT288 phone as it is programmed at delivery from the factory. There may be some differences in the way your system is programmed. Please consult your system administrator if you need further information.
