10.4.1 Scan

Press "Select" until "St" (Start) appears on the display.
Press "Enter" to start the scan, which continues until you press the "Enter" key for longer than 2 seconds again.
The scan can be left ON even for long periods.
During the scan the "Select" key is not active.
The following appear on the display in sequence:
•
the number of the channel acquired "Cnn" (nn= channel number 01-64, as well as activation channel "CA")
•
the corresponding signal amplitude "XX".
The signal amplitude is expressed in a logarithmic scale and may vary from –9 to 99 (see the table below).
SIGNAL LEVEL
much down
NOTES:
1. The value <0> corresponds to the minimum signal level considered "clear" (Amplitude –102dBm and Signal/Noise ratio > -
12dB).
2. When the scan function is ON, all other functions are OFF (the status of E86N outputs is the same as in an error condition).
3. The maximum values acquired are saved in a non-retentive memory and are therefore lost at switch off.
4. When a scan is started the previous maximum values acquired are deleted.
5. The scan time is approximately 1 second per channel, therefore a complete scan takes around 70 seconds. Since the system
can acquire only one channel at a time, the probability of detecting short-lived electromagnetic signals is increased by
extending the period of observation.
6. The values acquired are only made available after at least one full scan has been performed.
7. If there are two base stations, the highest of the two data items acquired is used.

10.4.2 Viewing results

Scan results may be viewed with three different types of systems:
Symbol System
HI Decreasing signal received
LO Increasing signal received
CH Increasing channel number
To view the results press "Select" until the symbol corresponding to the desired system appears on the display, then press "Enter".
The display shows first the channel number and then the signal value.
•
Press "Enter" to go to the next item in the list until you get to the last item.
•
Press "Select" to return to the previous item, until you get to the first item.
•
Press "Enter" for longer than 2 seconds to exit list scrolling.
