Programmable Function Keys
The basic version of the telephone provides 10 (COMfortel 1400 IP) or 15 (COMfortel 2600/3600 IP) programmable function keys, which the user simply presses to execute the functions configured on them. Each function key has a multi-colour LED that indicates its status, based on its assignment.
Note: In addition to the programmable function keys with LEDs on the right of the device, you can use widget functions to create up to 10 touch function keys on the home screens and the favourites bars.
Up to three COMfortel Xtension300 key extension modules (not included in the delivery) can be attached to the COMfortel 2600/3600  IP to add freely programmable function keys. Modules are attached to the right-hand side of the telephone. When the maximum number of modules has been installed, 105 freely programmable function keys are available.
The programmable function keys can each be defined twice (on two levels). You can configure how to access the second level of the function keys (Shift). Using the Shift key to access the second set of functions ("2nd level") is always enabled. If you want to use this method, you must assign the Level 2 function to one of your function keys. The "Double-click for shift" (300 ms) method can be disabled if it is not required (see chapter Settings > Function key > Settings Configuration Manager Function keys).

Directional Pad
The directional pad helps you navigating on the display and thus to use the keys to operate the telephone.
Press an arrow key on the directional pad to start key-based operation of the display and to enable the elements. Press the OK key on the directional pad to select the enabled element and run its function.
Elements on the screen change their background colour to indicate their state:
light blue: An element is displayed with light blue border if it was selected using the direction keys.
grey: The selected element is locked and cannot be selected by pressing the OK key.
Message Key LED
The message key LED shows the new entries in lists. The LED can be configured. Either it lights only if entries are not read yet, or if they are read but not deleted yet. If you find the LED signals disruptive or annoying, they can be switched off.
Proceed as follows for configuration:
Using the Configuration Manager (page Settings > Device > Display)
Using the telephone (page  > Settings > Device > Display)
Display-LED (only COMfortel 1400 IP and COMfortel 3600 IP)
The display LED signals the operational state of the telephone, missed calls and new messages. You can select different settings (see chapter Settings > Display > Configuring the Display LED (only COMfortel 1400 IP and COMfortel 3600 IP).
Sensors (only COMfortel 3600 IP)
Brightness sensor
If the automatic brightness adjustment function is switched on, the brightness sensor is used to adjust the display lighting to the brightness of the telephone's surroundings. The user can choose to either set te required brightness manually or switch to automatic adjustment (see chapter Settings > Display > Setting the Brightness of the Display).
Proximity sensor
The proximity sensors detect for example user proximity or a motion in front of the telephone. The sensitivity of the proximity sensors can be set (see chapter Settings > Display > Setting the Sensitivity of the Proximity Sensor (only COMfortel 3600 IP)). This can be used to exit the power save mode or the ring signal during a call via waving (see chapter Settings > Sound > Switching Silence on User Proximity On/Off (only COMfortel 2600 IP)).
