Changing Handsets
Your SUPERSET 4125 telephone 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 approcimately 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.
