H. MULTIPLE ENTRY
1. Disconnect the telephone line from the system and try dialing a number. If the system displays
a "LINE IN USE - PLEASE WAIT" message, this feature is working correctly.
2. Reconnect the telephone line and the system should beep and display the message
"LINE IS NOW AVAILABLE - PRESS # TO TRY TO CALL AGAIN". Make a call or press the
"✳" button until the welcome message returns.
I. METHOD OF DIALING
1. The Infinity is factory set to use DTMF tone dialing. To change to rotary (also called pulse)
dialing, enter the programming mode (see programming manual) and press "55" followed by
"ENTER".
2. When the new programming prompt appears on the screen, the change has been made. To
change the method back to DTMF tones, use the same procedure except substitute "60"
for "55".
J. OPTIONAL CCTV MONITORING
•
When the monitor or television is turned on, picture will appear.
•
If no picture appears, check the J1 connector on the CCTV power supply board. Make sure the
connector is firmly attached to the power supply board.
