The phones all include a stand that clips to the base of the phone. The stand allows the phone to be used in either of two different angles.
When changing the position of the stand, be sure to check that the stand has locked into the chosen position. A small plastic peg is located just under the phone's handset. This peg can be reversed to more securely anchor the handset when the stand places the phone in an upright position.
If the phone needs to be used in a situation other than on a desk, for example wall-mounted, a number of other stand designs are available from Avaya. Contact your system administrator.
