Introduction to the 9640/9640G Deskphone
If you have placed the phone vertically for wall mounting, reverse the tab located under the
switchhook in the top ear piece pocket on the phone to ensure that the handset is in the correct
position. You need a small screwdriver to lift the tab after it is reversed.
