The basic version of the device has 20 touch function keys which you can program to suit your needs. Each function key has a multi-colour display that indicates its status, based on its assignment.
The number of programmable function keys on the COMfortel ® D-400 can be extended by adding up to three COMfortel ® D-XT20 key extension modules (not included in the scope of delivery). Modules are attached to the right-hand side of the phone.
Note: If you connect more than one key extension module, use a COMfortel ® D-XT-PS power supply unit (not in the scope of delivery).
The programmable function keys on the key extension module can each be defined three times (on three levels). Consequently, in the fully extended system, there are 200 programmable settings.
Process for assigning function keys using the Configuration Manager
1.Select a button to which a function has not already been assigned.
2.Change to the right level, if required (Level 1– 3 tab, only extension module).
3.Select the function that is to be assigned to the button.
4.Set other necessary parameters, if necessary.
5.Save your settings.
The assigned key label is displayed in the screen.
The button can be used with the function that has been assigned to it.
You will find more information on this subject in the Edit function keys topic.
Extending the range of functionality using provisioning
You can use the templates in a provisioning file to extend the range of functions on the phone. These additional functions can be assigned to function keys.
Requirement for use
• Provisioning from PBX search enabled, see Provisioning
• PBX firmware from Version 7.4
• Suitable template < > phone assignment on the PBX
During the next provisioning process, the configurations in the template file are loaded into the phone. The additional PBX functions are in the Choose a function menu (phone) or Function menu (configuration manager) and can be assigned to the function keys.
