The instructions below are for both table/desk and wall installation.
1 Choose a spot near an electrical outlet and a telephone jack.
This phone requires a modular telephone jack and a standard
electrical outlet (110v AC) not controlled by a wall switch.
2 Install the handset battery.
Remove the battery cover by pressing on the indentation and
sliding downward.
Plug the battery pack connector into the handset, and place
the battery pack and wires into the compartment.
Replace the battery cover by sliding it on its track up over the
battery compartment until it snaps firmly into place.
