Cortelco 2720 Setup Instructions*

Updated by Hayden Everly on Feb 10, 2023

The Cortelco Phone is DISCONTINUED! Good-bye, old friend!

DESK MOUNT

1. Select the desired viewing angle and install the desk stand. The desk stand can be installed in two positions to give a choice of viewing angle.

2. Connect the power adapter. The power adapter connects to the jack marked DC 9V on the bottom of the phone. Plug the large part of the adapter into the wall outlet. Use only a 9V DC. 200mA or 300mA, center positive Class 2 adapter.

3. Connect the line cord(s). If you have Line 1 and Line 2 wired into one jack, connect the cord from this jack to the L1/L2 jack on the phone. If Line 1 and Line 2 are on separate jacks, plug the cord from Line1 into the L1/L2 jack and the cord from Line 2 into the L2 jack. Both of these jacks are on the bottom of the phone.

4. Plug the coiled cord into the handset jack, and then plug the other end of the cord into the base.

5. Place the handset on the base.

WALL MOUNT

1. Remove the desk stand. The unit will then mount directly on a standard wall telephone jack.

2. Connect the power adapter and the line cord(s). See Steps 2 and 3 above.

3. Rotate the handset hook into the wall mount position.

4. Plug the coiled cord into the handset, and then plug the other end of the cord into the base.

5. Place the handset on the base.

ANSWERING MACHINE

1. Connect the LINE jack of the answering machine to the wall telephone jack.

2. Connect the LINE jack of the model 2720 phone to the PHONE jack of the answering machine.

3. Set the answering machine to answer after 2 or more rings.
