Wall Mounting a Partner Telephone

WARNING: Do not attempt to unscrew the base from the phone. To do so will expose you to a risk of electrical shock.

Reverse the plastic hook that sits in the earpiece part of the handset cradle.

To attach the stand to the base of the phone, gently place the phone upside down with the low end of the phone to the

tight. Insert the tab on the narrow end of the stand into the left slot on the base of the phone. Then insert the other tab into the right slot, pushing the stand down and slightly inward until the tab locks into place.

Attaching the stand is a required step. Do not attempt to wall mount a corded PARTNER phone without first attaching the stand.

Finally, plug one end of the handset cord into the jack on the handset. Plug the other end into the small jack on the side of the base. If you need a shorter cord, use AT&T’s 2-foot D4BU-29 mounting cord (not provided).

Test the inside and outside line connections as described in steps 5 and 6 of figure 2-2.

Label the phone as described in step 8 of figure 2-2.

Test the telephone as described in figure 2-2.

Place the Quick Reference card near the telephone.

lNSTALLING STANDARD TELEPHONES AND OTHER

EQUIPMENT

Assemble the equipment according to the manufacturer’s instructions.

Plug the mounting cord into the modular wall jack. If the plug is loose in the jack, use an AT&T D2R mounting cord. To order, see appendix B in the System Manager’s Guide.

Test a telephone by lifting the handset. You should hear a dial tone, indicating a good connection on the line. If you don’t, see chapter 8, in the System Manager’s Guide, (“Phone HasLights but No Dial Tone”).

If you install a fax machine and want to assign a Fax Management button, see p. 3-29to program the extension as a fax extension.

If you install a doorphone, program the system to recognize the Door- phone and Doorphone Alert extensions. Seepages 3-32and 3-33.

INSTALLING TWO DEVICES ON ONE EXTENSION

CAUTION: To avoid malfunction, follow these installation instructions, not the ones provided with the equipment.

After assembling the equipment, plug the mounting cord of the non-PARTNER device into the top jack of the 267F2 bridging adapter. Plug the PARTNER phone or second standard device into the bottom jack (the one with four wires). If the standard device’s mounting cord is loose, use an AT&T D2R mounting cord instead.

2Plug the adapter into the modular wall jack or directly into the extension jack of a 206 module. Below is an example:

3Test the intercom and outside lines as described in steps 5 and 6 of figure 2-2.

4If installing two phones on one extension, test connection:

1Pickup the handset of the first phone and listen for dial tone.

2Pickup the handset of the second phone and listen for dial tone.

3If no dial tone, see chapter 8, in the System Manager’s Guide, (“Phone Has Lights but No Dial Tone”).
