4 Reverse the handset tab.
This tab holds the handset when you hang up. Hold down the
switchhook, and slide the tab up and out of its slot. Turn the tab
so that the end with the “hook” is up. Then insert the tab back
into its slot.
5 Plug the power cord into the jack labeled POWER.
(Make sure the plug is vertically oriented.)
Use only the power cord supplied with this product.
If you need a replacement, call 1 800 222-3111.
6 Connect the line cord to a modular wall jack and mount
the phone on the wall jack.
Make sure the cord snaps firmly into place. Place the phone on
the wall jack mounting studs and pull down until it is held securely.
