The phones all include a two-position stand that clips to the base of the phone as shown below. Once attached the stand can be used in either position to change the angle of the phone.
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.
On the 1416 and 1616 phones, the angle of the phone display can also be adjusted as shown below.
