The 

K-1900-4

will automatically dial a prepro-

grammed number, of up to 16 digits, whenever an
associated telephone is taken off hook. Using non-
volatile E

2

memory, the 

K-1900-4

is telephone line

powered and will operate on any loop start central
office line or analog PABX/KSU extension.

The 

K-1900-4

is easily programmed remotely or

locally using a standard Touch Tone phone.

Why pay the premium of leased or dedicated phone lines?

This product does not eliminate the

possibility of toll fraud!  To further protect
against fraudulent calls, order a “pulse
only” phone line from your local phone
company.
