Getting to know the display and controls

Display (see → Getting started → Getting to know the D735 components → 5)
This display presents the following information:

In idle mode:

When the phone is active:

1. Info bar/status line
   • In idle mode: when there are active status messages → Status messages and when there are no active status messages → Date and time
   • When the phone is active: Name of current activity
2. Context area:
   • In middle mode: Configured identities and their actual state and SmartLabel
     
   • When the phone is active: Depending on the activity, this area will contain symbols (incoming call ringing, outgoing call ringing, list entries, etc.) and text like the phone number calling, the extension number being called, conference partners, etc. Depending on the context, the SmartLabels will or not be shown.
     
3. Function key line, context-sensitive:
   Depending on the current activity of the phone, the function key line will present various functions that can be activated by pressing the function key underneath the respective symbol. (see → Context-sensitive, programmable function symbols and function keys)
   Call indicator (see → Getting started → Getting to know the D735 components → 6)
   The bright-red LED situated on the top right corner of the phone indicates incoming, ongoing, held, and missed calls. LED status indications:
   • Blinking rapidly when a call is coming in.
   • Glowing steadily when dialing, when in a call, and when you have missed a call. To turn the LED off after a missed call, press the right arrow on the navigation key to view the Missed calls menu and simultaneously turn off the LED.
   • Blinking slowly when you have put a call on hold.
     SmartLabel keys (see → Getting started → Getting to know the D735 components → 7)
     8 SmartLabel keys (freely programmable function keys with LEDs) on the both sides of the display control the SmartLabels. They can be programmed and labeled on the phone via menu-driven phone user interface (PUI) and on the Funct ion Keys page of the phone's web user interface (WUI).
     
     Each of the 8 physical keys can be assigned to different functions on 4 Smart Label pages, which finally gives a total number of 32 SmartLabel keys.
     
     You can switch between the SmartLabel pages using the following key:
     

Depending on the function mapped onto the key, the red or green LEDs on the key will be activated when the key event occurs. The LED of a line key will

• blink rapidly when a call is ringing on the line
• glow steadily when there is an ongoing call on the line
• blink slowly when a call is on hold on the line
• be off when the line is free.

When other functions are mapped onto the keys, the LEDs may glow or blink. For example: When the extension function has been mapped onto a key and monitoring of extensions is enabled on both phones, the LED will

• blink rapidly when a call is ringing on the extension
• glow steadily when the extension is busy
• be off when the extension is not busy

Context-sensitive, programmable function symbols and function keys (see → Getting started → Getting to know the D735 components → 8)
4 context-sensitive, programmable function keys (F1 - F4) are located directly below the display and can be programmed on the Function Keys page of the phone's web interface (WUI) with a number of key events; these functions will then be available when the phone is in idle mode.
