snom 220 additional Keypad
This expansion module is designed for use or connection with the VoIP phone snom 220.
Please observe the instructions in the snom 220 user manual.
Installation procedure
• Unplug the power connector from the snom 220 phone
• Place the telephone and the additional keypad upside down on a soft surface so that you can
read nameplates from the front (see gure). The additional keypad must be placed to the
left of the telephone. The xing holes in the additional keypad must be positioned over the
corresponding screw domes on the telephone (3).
• Secure the additional keyboard to the telephone with the studs supplied (3)
• Connect the connection cable (4) as shown in the gure and secure it under the cable holder
(5).
• Fasten the support (8).
• Now turn the telephone and additional keypad over and set them on the rubber supports.
• Plug in the power connector of your phone. LEDs on the keypad will ash. Wait for the snom
220 to boot completely. All LEDs will turn off. The additional keypad is immediately ready for
operation.
• The very rst additional keypad connected to the snom 220 gets its power from the phone
and does not need an external power adapter.
• THE PHONE POWER SUPPLY IS 48V, which is different from the keypad power
supply. It will damage the keypad if accidentally plugged into the keypad.
DO NOT connect the phone power supply to the keypad!
Programming the additional keyboard
Configure the function keys on the extension board using the built-in web interface of the
phone. These keys can be used for Line, Destination, Intercom, Park Orbit, or Voice Recorder
mapping. The default operation is Line. The LEDs associated with each key will reflect the status of
that line, e.g. ringing, on-hold, connected call, etc.
Changing the label
The label panels for the function keys are included on a separate sheet enclosed with the
[ S N O M 220 ADDITIONAL K E Y P A D V1.00 ] [ S N O M 220 ADDITIONAL K E Y P A D V1.00 ]
operating instructions. Cut out the label you wish to use. To change the label panel, press the
flexible cover together between your index finger and thumb and lift it out. The label panel can
now be changed.
Connecting further keyboards (cascading)
Up to three additional keypads can be connected (cascaded) to your telephone. A plug-in
power supply is required if you use more than one additional keypad. Use only the approved
power supply units available as accessory (plug-in power supply unit t400/Ident-Nummer:
220872.5, plug-in power supply unit t400-UK/Ident-Number: 220873.3).
Installation procedure
• Unplug the power connector from the snom 220 phone.
• Proceed as described for the telephone and rst additional keypad, i.e., turn them upside
down and place the second additional keypad to the left of the rst one.
• Afx the additional keyboard at the positions (10) marked in the illustration. Plug the
connecting cord into the left jack (7) of the rst additional keypad and into the right jack
of the new module. If you add a third additional keypad, attach it to the second one in
the same manner.
• Plug the keypad power supply into the appropriate jack for the second additional keypad.
DO NOT connect a separate power supply to the third additional keypad; it takes its
power from the second one.
• Finally, plug in the POWER connector of your snom 220 phone. LEDs on all connected
keypads will ash.
• Wait for the snom 220 to boot completely. All LEDs will turn off. The additional keypads
are immediately ready for operation.
• When you perform soft reset on the phone there is no need to disconnect the power
upply on the second cascaded keypad.
• THE PHONE POWER SUPPLY IS 48V, which is different from the keypad power
supply. It will damage the keypad if accidentally plugged into the keypad. DO
NOT connect the phone power supply to the keypad.
