D4 or D5? What's the difference?
The clear difference between the two handsets is that the D5 is larger than the D4 and has more programmable BLF/DSS keys either side of the LCD display. The D4 has four keys either side, the D5 has five keys. There are other, more technical differences which can be found in the product manuals (D Series Handset Manuals).
Putting the Handset Together
When you receive you handset, it will be neatly boxed and will contain:
- The handset body
- The receiver
- The handset stand
- "Curly" cord
- Patch cable
Firstly, locate the handset body and the handset stand. The stand should attach to the rear of the handset, slotting into one of two sets of grooves. These are at different levels to allow you adjust the angle that the handset sits on the desk. The handset is also wall mountable and instructions to do this can be found in the relevant handset manual (D Series Handset Manuals).
Next, find the curly cord and receiver. Connect the curly cord to the receiver, either end of the cord will work, you should hear a sight click when it is correctly connected. This is the securing tab locking into place. Then, identify the receiver socket on the handset base. This is marked with an image of the receiver and plug it in.
You can then follow the instructions in The Basics - Handset Configuration article to get the phone up and running.
What Do The Buttons Do?
Both models of handset have the same keys with the same functionality, with the exception of the BLF/DSS key described above.
Here is a brief description of each keys function:
Soft Function Keys – These four buttons provide different functions corresponding to the description directly above them on the handsets screen. These will change depending on what the handset is doing. I.e. different functions are displayed while in a call and while the handset is idle.
BLF/DSS Keys - These keys can be configured from the Portal (if the handset has been auto provisioned) by clicking on the "Spanner" icon in the SIP accounts widget. Here, extra line keys and BLF keys can be configured. The Page Key cycles through the available BLF/DSS key pages.
Navigation Keys – Users can press up/down left/right navigation keys move through the menus on the handsets screen. You can also use these to move between characters in text editing screens. The OK button in the center acts as a confirmation button or enter key.
Standard Telephone Keys – The 12 standard telephone keys provide the same function as standard telephones. Please note, some system announcements may say "followed by pound". This is the # (hash) key.
Voicemail - This key will dial into the primary SIP accounts voicemail. The allows you to recover messages, save message, set an outgoing message. This has the same function as dialing *98 from the SIP 1 account.
Headset - This key functions similar to the Speaker key, except audio will be transmitted and received by a connected headset.
Redial - Pressing this key will call the last dialed number.
Speaker - Pressing this key will enable the loudspeaker under the receiver and microphone to allow the user to make or receive a call while the receiver is still "on hook".
Volume Keys - While the handset is idle, these keys will adjust the ringer volume. In a call, they will adjust the speaker volume on the handset, receiver or head set.
Mute - In idle, pressing this will enable Silent Ring mode, when in a call, it will mute the microphone of the handset, receiver or headset.
