User and service manual
The keyboard has 2 functioning keys
–
key symbol
= after pressing a
number combination van be inputted to control relays. Second key
–
symbol X
= after pressing the system always disconnects.
Choosing number on the keyboard can be done
in two ways (
parameter 49
):
- visitor chooses keys like on a phone
– the
length of time between the presses must be
less than the time given in
parameter 53
, after
this the system picks up and dials the given
number.
- Visitor chooses a 2 digit number (from 01 to
99), which represents a memory number where a number is saved
(max. 24 digits long) as per the buttons. The number choice is
dependent on the regime setting (i.e. Day/Night) or by regime 2 groups
of numbers (as is described in chapter 5.1).
3.4 Acoustic path setting
The principle of setting acoustic paths:
Here we have three parameters 71.72 and 73 Using the interaction of these
parameters can be set to sound in different conditions.
1. quiet environment parameters 71,72,73 are set to 7
2. environment where is a strong ambient noise at the communicator and
quiet environment at the phone. Here is both necessary to reduce the
microphone gain (parameter 72 = 1-3) and also change the ratio of the
parameters 71/73 way 73 enlarge the the parameter (parameter 73 = 11-
15) and 71 parameter smaller value (71 = 2-4)
3. environment where is a strong ambient noise at the phone and quiet
environment at the communicator. Here we leave the parameter value of
72 = 7 and 73 and 71 parameters set as follows - parameter71 = 11 to 14
and 73 = 2 to 4
The principle of settin parameters is - signal from the microphone is amplified
by the sum of parameters
72+71 = volume of microphone
and signal to the
speaker is amplified by the sum of parameters
71+73 = volume of speaker
.
To switch the direction of the ratio is evaluated parameters (
threshold
) 73/72.
-
If parameter 72 is greater than the parameter 73, thus favoring the
direction from the microphone. We choose when the direction to the
phone is interrupted.
-
If parameter 73 greater than parameter 72, thus favored direction to
the speaker. We choose this if the interrupted sound in the speaker of
communicator.
