SECTION 1 – GENERAL DESCRIPTION OF THE MASTERCALL SYSTEM
The MASTERCALL Call Diverter manufactured by Design Two Thousand Pty Ltd diverts incoming calls on one line via
a second line to any dial up telephone number. Incoming phone calls are redirected to the required number via the normal
public switched telephone network (PSTN). ‘Double’ diversion and diversion to international numbers is possible with this
system.

Series 8 is the new flagship model. It is the digital successor to the well-proven MC-4044 Series 5.
Things that make the new Series 8 unique are full remote programmability without the need for a modem, real voice
prompts to the user, and the many advantages of digital signal processing.

SECTION 2 – INSTALLATION INSTRUCTIONS
Two telephone lines and a mains power point are required for Mastercall to operate. Batteries are NOT required to retain
data in memory nor to retain ialingdd announcements. An optional battery standby system is available to keep
Mastercall diverting in the event of mains power failure.
Several software facilities need to be programmed, including entering the diversion number and selecting the required
Recorded Voice Announcements (RVA). These are described in Section 3. All programming operations can be performed
using the inbuilt Keypad or by Remote Control over the telephone.
Diverter Connection
The diverter is connected to the telephone lines using the line cords provided. To check the connection, a telephone should
get dial tone when plugged into either telephone socket.
The12V power adaptor is connected to the diverter power socket at the rear of the unit and to a mains power point at which
time the ‘POWER’ LED will light up.
Once installed, the Call Diverter diverts calls that come in on line one (factory setting).
