Self-labelling of the keys

The Expansion Module is equipped with a large 7” display to show the function of the keys. The key’s function is displayed next to the key and any changes to its function will automatically appear in text. Writing with a pencil is no longer necessary.

Programmable keys

The module adds 58 additional keys spread over two pages. One key is used to toggle between the pages and the module’s other keys can be used for functions such as BLF and speed-dial. For convenience they can also be programmed as access codes, voicemail activation or to login to your device.

Telephone expansion

Maxwell Basic, 2, 3 and 4 support up to 3 Expansion Modules, offering the user more buttons for additional function settings  and adding as many as 174 more possible configurations. The first Expansion Module uses the power supply while the second and third connect to the first Expansion Module.


Keys with 3 colours

Each key consists of a coloured LED representing several status indicators. A green light means the line is available, a blinking red light signifies an incoming call, a solid red light indicates the line is busy and yellow means offline.

Matching Maxwell Design

The design of the Maxwell Expansion Module matches the look and feel of the Maxwell series. Everyone uses their phone in a different way, so the Maxwell series supports a movable foot which allows for three different positions from vertical to horizontal. The Maxwell phone and Expansion Modules also supports wall mounting.
