Plug the system in to power it up. Once powered up, the system’s blue LED 

will blink rapidly, 4 impulses per second (IPS). After 5 seconds, it will begin 

blinking at the normal operational rate of 1 IPS. To ensure that the X16 system 

is initialized properly, switch the “INIT” switch back and forth three times 

within three seconds. When the LED returns to 1 IPS, the system will be fully 

operational.

Your installation may look something 

like this. 
In this example, The telephone 

company’s telephone lines are 

connected on the right side and 

telephone line 1 is looped to all of the 

extensions, 1, 2, 3 and 4, which are 

connected on the left side.  
When ordering your telephone lines, it 

is a good idea to ask for the lines to be 

delivered on a “Surface Mount Jack” 

or with existing installations you can 

use a “Testar_2 Connecter”, which will 

make the installation of the 

 

X16

 much 

easier.
Telephone professionals use a 

standard color code when connecting 

telephones and telephone lines.  The 

white/blue pair, indicated by “Ext 1, 2, 

3 and 4, is normally connected to the 

office’s telephone jack.
One way to reconfigure this type of 

installation is to remove each of the 

extension (Ext) cables and connect 

the white/blue cable to the red wire 

and the blue/white (or solid blue) cable 

to the green wire. Another way, is to 

connect a “Testar_2 Connecter” (see 

Ext 4), which simply slips over the 

pins. 
Now connect the supplied line cords 

between the surface mount jack or 

Testart_2 connecter and the ports in 

the 

X16 

system. You can connect 

them directly, 1 to each port, or using 

the supplied splitter.

The 

X16

 system can be placed on a table or mounted on a wall.  It should be located 

close to where the telephone lines come into the building and plugged into a 110 

electrical power outlet.  Only the 

X16

 system needs to be plugged in, all of the 

X16

 

telephones and the Cordless Telephone Module are powered by the system.  

Telephone lines are usually found on the center pair (Red/Green) of the telephone jack 

(RJ11). Sometimes a second line will be connected 

to the outer pair (Black/Yellow) (RJ14). The 

system is designed to accommodate both types 

of installations. When using only the center pair, 

connect 1 telephone line to each of the 4 ports in the 

system. When using both the center and outer pairs, 

use only ports labeled 1/2 and 3/4 to connect all 4 

telephone lines. 

Your existing cabling will determine how the 

telephone lines will be connected to the system. 

Note: The port labeled “Line1” is not used for a telephone company telephone line.  It is 

designed to give you access to the telephone company line 1, which is plugged into the 

Central Office Port labeled 1/2. This is useful during a Power Failure or anytime you want 

to access line 1 from a cordless telephone.
