2.5. Wall Mount

b. Connect the line cords as described above.

wall outlet which is not controlled by a wall switch. Use only a 9V DC 500mA, Class 2
transformer.
2.6. Verify Proper Installation
This procedure should be used at each telephone after initial installation. It may also be used if you are
having problems with your system. First, verify the three items below at each telephone in the system.
a.. Verify that the AC power transformer is connected to the 2742 and to the mains power.
b. Verify that Line 1 is connected to the 2742.
c. Verify that a station number has been assigned. Go off hook on your cordless phone and dial
another station in your system (01 – 16). The phone should ring and display the incoming
station number. Note that this assumes that the system contains one or more 2740s or 2750s.
Now, verify that Line 1 has been connected correctly to all telephones.
d. Go off hook on your cordless phone and dial 81. Verify that the Line 1 LED is red at each other
station.
To verify the connection of lines 2-4, perform the following steps at each telephone. Note that this
assumes that all lines are connected to all telephones. Remember that Lines 2, 3, and 4 may not be
common.
e. For Line 2, go off hook on your cordless phone and dial 82. Verify that the Line 2 LED is red at
each other station.
f. For Line 3, go off hook on your cordless phone and dial 83. Verify that the Line 3 LED is red at
each other station.
g. For Line 4, go off hook on your cordless phone and dial 84. Verify that the Line 4 LED is red at
each other station.
Note: The cordless adapter will show lines that are seized by other 4 line units. This is shown by a red
led on the front of the unit.
