1.3.10. Verify Proper Installation
The following procedure should be used at each telephone to check for proper installation. Also use this
procedure any time you are experiencing difficulty. The phone must be connected to the AC power
supply, line 1 must be connected to the line 1 jack, and the phone must have been assigned an intercom
station number. First, verify that line 1 is connected to the same telephone number at all the telephones.
To do this, press the line 1 button at one of the telephones. The line 1 LED should be green, the
speakerphone LED should be red, and dial tone should be heard from the speaker. Now go to each of
the other stations and make sure that each line 1 LED is red. Next, make sure that lines 2, 3 and 4 are
connected the same at all the phones by performing the following steps at each telephone:
a. Press the line 1 button. The line 1 LED should be green, the speakerphone LED should be
red, and dial tone should be heard from the speaker.
b. Dial the telephone number for line 2. The line 2 LED should flash slowly. If the line 2 LED
does not flash, then line 2 is improperly connected to this telephone.
c. If this telephone utilizes line 3 and/or line 4, repeat steps 1 and 2, substituting the respective
phone number(s) in step 2.
