To mount the phone on the wall:
1. Put the corded handset aside. Use a coin to rotate the handset tab 180 degrees.
The protruding edge holds the corded handset when the phone is mounted on the
wall.
2. Connect the network cable(s) and power adapter (if required).
3. Align the upper wall mounting hole on the back of the phone with the upper tab
of the standard wall plate. Make sure the lower wall mounting hole on the phone
also aligns with the lower tab of the standard wall plate. Push the phone down
until it clicks securely in place.
4. Bundle the network cable(s) and power adapter cord (if using the power adapter)
neatly with twist ties.
