b. Enabling/Disabling Central Station Mode
The
1600A
Series emergency phone can be placed in the “Central Station Mode” by entering a central station
phone number in position
#05
while programming. To cancel the “Central Station Mode,” clear position
#05
by
entering
#05
only (see
Programming
section
D
).
c. Ring No Answer
When the
1600A
Series emergency phone is in the “Central Station Mode”, it is best to have the ring no answer
set to a minimum of three, because some receivers send a long tone after answering the line that sounds like
a ring back. If the
1600A
is set to a ring no answer of two, the phone will disconnect (see
Programming
section
F
).
a. Accessing the Programming Mode
Before programming, you must access the programming mode (see
Programming
section
A
).
