SECTION 5  INSTALLING A DTERM® CORDLESS LITE TELEPHONE
The 
Dterm 
Cordless Lite telephone [DTU-4R-1 (BK) TEL] can be used with the
InfoSet system.  The cordless telephone is connected to the system using an ESI
port.  The cordless telephone provides the user the ability to be away from their
desk, yet still be able to have access to their telephone. 
5.1 Selecting an Installation Location
Select a location for the Dterm 
Cordless Lite telephone to avoid excessive
heat or humidity.  The base unit should be placed on a desk or tabletop
near a standard 120 Vac outlet and within reach of the telephone line
connection on the Electra Elite telephone.  Keep the base unit and the
handset away from sources of electrical noise (motors, fluorescent
lighting).

5.2 Connecting the Telephone Cords
The Dterm Cordless telephone can be connected to either the telephone
line or a line with the host telephone.  Begin by unplugging the telephone
line cord from the host telephone to the telephone line. 
There are two telephone line jacks on the back of the base unit of the 
Dterm
Cordless telephone;  LINE IN and LINE OUT.
Using the telephone line cords supplied with the 
Dterm Cordless telephone,
make the following connections:

Connect the LINE IN jack to the telephone line.

Connect the  LINE OUT jack to the host telephone.       

Never install telephone wiring during a lightning storm.

Never touch uninsulated telephone wires or terminals unless the
telephone line has been disconnected at the network interface.

Use caution when installing or modifying telephone lines.
5.3 Applying Power to the Base Unit
1. Plug the AC adapter cord into the AC adapter input jack on the base
unit.
Use only the AC adapter supplied with the 
Dterm Cordless
telephone.
2. Plug the AC adapter into a standard 120 Vac wall outlet.
3. Route the power cord where it does not create a trip hazard or where
it could become chafed and create a fire or other electrical hazards.
The AC adapter furnished with this phone can be equipped with
a polarized line plug (a plug having one blade wider than the
other).  This plug fits into the power outlet only one way.  If you
cannot insert the plug fully into the outlet, reverse the plug.  If
the plug still does not fit, contact your facilities coordinator
about replacing the obsolete plug.  Do not alter the shape of the
blades of the polarized plug.
Observe the following warnings during  installation.

6.2 Connecting the Telephone Cords
The Dterm Cordless Telephone can be connected as a stand-alone device
or in conjunction with the digital host  telephone.  Begin by unplugging the
digital telephone line cord from your host telephone.  There are two RJ-11

cable for the 
InfoSet Type Telephone Interface.  Always open the
red and green wires inside the wall jack.  This is done to reduce the
potential for interference.
(Refer to Figure 2-42 Connecting and Supplying Power to the Base Unit on

SECTION 7REPLACING BATTERIES AND FUSES
7.1 Replacing the Backup Batteries in the KSU
These batteries provide power for the system in case of a power outage.
Fully charged batteries provide power for approximately 30 minutes.
When replacing these batteries use a 12V 0.8A rechargeable lead acid
battery.
1. Be sure the system is turned 
off during the installation process.
2. Remove the cover by loosening the two bottom screws with a Phillips
head screwdriver (the screws remain in the cover to keep from
misplacing them).  Pull the cover away from the KSU and lift upward.
(Refer to Figure 2-1 Removing the Front Cover on page 2-2.)
3. Remove the screw that is attached to the grounding cable and loosen
the second screw that secures the metal plate to the batteries. Slide
the metal plate until it clears the remaining screw and lift upward to
remove the metal plate.

5. Lift out the old batteries.
6. Insert the new batteries into the slots.  Place the notched end of the
battery toward the casing on the KSU.  Place the battery cables
between the inside of the battery and the posts located on the inside
of the battery casing.  
7. Replace the metal plate on top of the new batteries.  Place the
grounding cable on top of the hole and tighten the screw using a
Phillips head screwdriver.   
8. Locate the backup batteries in the lower left side of the KSU.  Identify
the battery cables, which are marked with blue and yellow tags.
Attach the blue tagged battery cable connector to the blue battery
terminal labeled CN3 (BATT1) and the yellow tagged battery cable
connector to the yellow battery terminal labeled CN4 (BATT2).  The
battery terminals are located on the backplane of the KSU.  The
connector tab should be placed over the terminal tab.   There is only
one direction the tabs can be placed into the connector terminals,
therefore, you cannot attach them incorrectly.
