3  Configuring the Call Recorder  
A newly installed Call Recorder needs to be configured for the desired 
applications. The configuring menu can be reached by pressing 
. You will 
then be asked to answer a few important configuring questions, regarding the 
clock, for example, or, in one of the sub-menus, the telephone settings. 
In this chapter only configuring the recorder for use as a call recorder is 
discussed. 
3.1  Aspects of Configuring 
Access to the recorder may have been secured with a password. At delivery 
this is not yet the case. 
W hen installing, you will find the options represented by the softkeys 
indicated on the display. You can scroll through the options with the recorder 
keys.  
    selects the previous menu function 
    selects the next menu function (similar to  ‘NEXT’) 
3.1.1 Recording From: 
Press 
 and you will see: 
Record from : Line
NEXT CHANGE STOP 
This selects the source from which the recorder will automatically record. 
By repeatedly pressing  the ‘CHANGE’ softkey, you can select one of three 
possible sources: 
• Line, if the telephone line has been connected to the recorder   
						

							Call Recorder Manual ©-2001 Vidicode Datacommunicatie BV  24 • Handset, if the handset has been connected to the recorder 
• Microphone, if you want to record automatically from the 
microphone 
The recorder can only record automatically if the source of the signal has 
been correctly set.  
3.1.2  Setting the Start Signal 
The display will show: 
Start: Series off-hook
NEXT CHANGE STOP 
It is important to know which signal the recorder uses to start and stop a 
recording. These are the possibilities: 
Phone in series 
The telephone has been connected to the Phone port of the recorder. The 
recorder reacts to the current that flows from the telephone exchange to the 
appliance when the handset is taken off the hook, which is an extremely 
reliable method. However, it can only be used when one is recording from the 
line. 
Phone in parallel 
In this case the recorder and the phone have been connected in parallel. The 
recorder reacts to the voltage level. It is another very accurate way of 
determining the beginning and end of a telephonce conversation. The huge 
drawback of this method, however, is that recording starts as soon as the 
connection between the recorder and the line is interrupted. For this reason it 
is recommended that it should only be used when the recorder has to listen to 
a line that may not be led via the recorder. This method can only be used 
when recording from the line.   
						

							Call Recorder Manual ©-2001 Vidicode Datacommunicatie BV  25 Speech detection  
In this case the recorder reacts to a signal on the line. Speech detection 
should be used in combination with “Signal Setting”, which is discussed 
below. Speech detection is not advisable when one is recording from the line, 
as the recorder might be set off by not just speech, but by any other signal on 
the line, such as a ring from the phone. 
Opening contact or Closing Contact 
These settings are used when the “Switch” port of the recorder is connected 
to an external contact such as can be found in various telephone exchanges 
and apparatuses. Recording starts whenever the external contact opens or 
closes. 
Manually 
Of course it is also possible to start recordings manually. W hen manual 
recording has been selected, recording is started by pressing the Record 
button and stopped by pressing the Stop button. Note: This setting is an 
exception because the normal function of the Record button is not to start a 
microphone recording, but to answer the question from which source one is 
recording: line, handset or microphone. 
3.1.3 Signal Setting 
This question concerns the level of the signal above which the recorder will 
automatically start to record. Only when speech detection has been selected 
in the preceding question will the following question be shown on the display: 
Signal Setting
NEXT CHANGE STOP 
To set this select ‘CHANGE’ and the signal level measure will appear on the 
display: 
A4•:|
> BACK  
						

							Call Recorder Manual ©-2001 Vidicode Datacommunicatie BV  26  Any signal made now will be graphically represented in the following way: 
A4■■■■■■■■
> BACK 
A signal beyond the bar is sufficient to start the recorder, with the bar 
indicating the minimum signal level necessary for recording to start. The 
colon indicates the switch-off level. Recording stops when the signal stays 
below the switch-off level for a certain time (manufacturer’s setting is 10 
seconds). Normally the switch-off level will be lower than the switch-on level, 
so that recording will take place even if somebody speaks in a low voice.  
Below is a table with the functions at your disposal when setting the signal 
level: 
Key 
Function 
Softkeys > Move the swith-on level  - indicated by the bar 
  Move the switch-off level - indicated by the colon (:)  
0 to 7 Set the level of both simultaneously from 0 to 7 
# By pressing # the channel (microphone or loudspeaker) on 
which the recorder starts is changed (only when lifting 
the handset). Also important for setting the amplification 
for each channel
 
* By repeatedly pressing * the amplification factor of each 
channel can be individually adapted from 0 to 7  
 
Tip:  Sometimes the microphone of the telephone produces a significant signal even when the handset is on the hook. This would set off the recorder if somebody close to the phone were to speak in a loud voice. You can prevent this by simply selecting the opposite channel before recording. 
3.1.4  Procedure for setting the signal level of speech detection 
This paragraph is only applicable to the use of speech detection.  
						

							Call Recorder Manual ©-2001 Vidicode Datacommunicatie BV  27 Setting the signal level for speech detection is sometimes found difficult. 
However, setting it correctly only has to be done once, will prevent future 
problems, and boosts the quality of recording. 
W e advise you therefore to adjust your Call Recorder to your handset in the 
way described below. Before you start adjusting, all cables should have been 
properly connected. 
Proceed as follows: 
1.  Enter the menu via the menu key 
2.  Select “lifting the handset” with the ‘CHANGE’ softkey 
3.  Press the ‘MORE’ softkey. You will now see the “start” menu 
4.  W ith the ‘CHANGE’ softkey select “speech-detection” 
5.  Press the ‘MORE’ softkey. The display will now say “signal setting” 
6.  Press the ‘CHANGE’ softkey. 
 
You have now reached the graphical screen for adjusting the signal level and 
the start and stop levels.  
A4:|
> BACK 
In order to get the correct settings dial a telephone number and with the help 
of the person on the other end set the Call Recorder . 
W hen connected proceed as follows: 
1.  Check if the signal comes to about halfway along the scale when 
speaking. 
2.  If the signal remains continuously in the lower half, select * to 
increase the amplification (A 4 changes to A5, A6, A7) 
3.  If the signal is well beyond the middle during a normal conversation, 
continue pressing * until you see A0, A1, A2 appear. 
4.  Now press the # key. You will see the B channel (display says B4)  
						

							Call Recorder Manual ©-2001 Vidicode Datacommunicatie BV  28 5.  Check the amplification just as you did with the A channel, and 
adjust if necessary. It is quite possible that one of the two channels 
reacts in a totally different way from the other. This is normal as one 
channel represents the speaker in the handset, whereas the other 
one represents the microphone of the handset. It is important that 
both the local speaker and the recipient can be seen properly on 1 
channel. 
If the previous instructions have been executed properly, you will be certain of 
a good quality recording. Next the start and stop levels will have to be set as 
well. These are important to ensure that the Call Recorder will start and stop 
a recording as accurately as possible. It is done as follows in the same menu: 
1.  Press the # key till it shows the A channel. 
2.  The starting level is represented by a vertical bar (I) on the display. 
3.  Check that the signal exceeds the start level during a conversation. 
4.  Change the start level by moving the softkeys> to the left or 
right to adjust it when necessary. 
5.  The stop level is indicated by a colon (:) on the display . 
6.  Check if the signal drops to below the stop level when you put the 
handset down (often the signal disappears altogether). 
7.  Move the stop level with the normal > keys to the left or 
right until it is about 1 or 2 points to the right of the signal, if visible. If 
no signal is visible at all, set the stop level at the 2
nd point. 
8.  Make another telephone call. 
9.  NOTE! During a normal conversation the signal should not drop 
below the stop level on either channel A or B. Check this by 
interchanging between the channels with #. 
10.  Press the ‘BACK’ softkey.  
11.  Press the ‘STOP’ softkey. 
The procedure is now completed. You are advised to test that the Call 
Recorder is indeed working properly. This is done as follows: 
1.  Start a telephone call ( the Call Recorder should start recording).  
						

							Call Recorder Manual ©-2001 Vidicode Datacommunicatie BV  29 2.  Record a minimum of 1 minute of conversation. 
3.  Replace the handset. 
4.  Check that recording stops automatically (this should take about 10 
seconds). 
5.  Press the “Call Recorder” key.  
6.  Press the ‘LAST’ softkey. 
7.  Listen to the conversation and check that it is of sufficient quality. 
8.  Press the ‘STOP’ softkey. 
If this test went well and the conversation has been recorded without 
interruptions or other malfunctions, the Call Recorder is ready for use. If the 
conversation did not sound good, or the recording did not stop, we advise you 
to repeat the procedure described above carefully. Some telephones 
connected via the handset cannot easily be adjusted, depending on the type 
of handset. An alternative solution would be to start manually or with a start 
contact, but this is only necessary on rare occasions.

NEXT CHANGE STOP
This allows you to select the compression factor used when the digitalised 
recording is being stored. Lower compression uses up more memory but 
gives a better quality recording. See paragraph 1.2 for a detailed discussion 
of this subject. It is advisable to leave it at the manufacturer setting ‘Digitalk’ 
when using the Call Recorder for the first time.
