"PT" is used as a generic term to represent all of these PTs. If a PBX feature only supports specific PTs,
such as IP-PTs, the available telephone types are clearly indicated.
• IP-PTs may become busy and you may not be able to make or receive calls, depending on the network
status.
• The contents of this manual apply to PBXs with a certain software version, as indicated on the cover of
this manual. To confirm the software version of your PBX, consult your dealer.
• Product specifications are subject to change without notice.
