CONVERTING FROM DESK TO WALL MOUNT
The BTX4550 telephone can be wall mounted. It is easiest to do the conversion when the handset and line
cords are not connected.
1. Located on the front of the telephone above the speaker grill is the wall/desk mount clip. Remove this clip
by firmly pushing upward (toward the hookswitch).
2. Rotate the clip a half turn (180 degrees) so that the side with the protruding edge is towards the top.
This edge will hold the handset.
3. Slide the clip downward into the same slot until it stops (snaps into place).
4. Turn the BTX4550 over (place on a non abrasive surface) so the back side is up, facing you.
5. Locate the mounting bracket, and firmly push back and pull up to remove. NOTE: There are (4) retaining
tabs.
6. Rotate the mounting bracket a half turn (180 degrees) so that the mounting eyelet is facing in the same
direction as the mounting eyelet located on the bottom surface of the telephone.
7. Insert the top two retaining tabs of the mounting brackets into the mounting bracket slots located near
the middle of the telephone, then firmly push down and insert the retaining tabs on the opposite side.
8. Connect a short modular line cord into the jack on the back of the phone (labeled TO TEL.). Route the line
cord through the line cord channel. Connect the other end of line cord to the phone jack on the wall mounting
plate.
9. Turn the telephone over, and slide the BTX4550 onto the mounting posts on the wall plate in a downward
direction. Both eyelets should line up with the mounting posts (When properly installed the telephone will be
stable and secure.)
10. Complete the wall mounting by installing the handset and handset cord.
