Connection and conditions for use.
You can connect your Concept Combo 2300 to a direct exchange line (DEL) - a line
connected to a local exchange, with its own phone number; to an extension on an approved
compatible PBX. Do not connect the Concept Combo 2300 as an extension to a payphone.
The ringer equivalence numbers (RENs) of all instruments (phones, fax machines, etc.)
connected to an exchange line must not add up to more than 4 - otherwise, one or more
of them may not ring and/or answer calls correctly. The Concept Combo 2300 has a
REN of 1, and most other telephones have a REN of 1 unless marked otherwise.
