Changing Handsets
Your 5020 IP Phone is compatible with several specialty handsets. To remove the handset shipped with your phone from the handset cord:
1.Bend a paper clip to produce approximately 4 cm (1.5 in.) of straight wire.
2.On the handset, locate the plastic groove leading into the handset jack. The groove is on the side of the jack that is closest to the handset microphone.
3.Slide the end of the wire into the handset jack along the groove until it stops underneath the handset cord clip.
4.While gently pulling on the handset cord, use the wire to pry the clip upward. The cord will separate from the handset.
5.Store the original handset in a safe place.
