VVJ-8718-19/FE HF RECEIVER
INSTALLATION AND OPERATION

Threshold Level
During all MFP scan operations, the recei-ved signal strength is compared to
a selected threshold level.
The threshold levels are entered as single digit codes
which are stored, along with the receiver parameters, in the memory channels.
Table
2-2 lists the single digit threshold level codes and their corresponding signal strength
levels in dBm.
Table 2-2.

* NOTE:
1.
An entered threshold data code of 0 causes the
SCAN to stop, regardless of signal strength, at the
channel where the 0 is stored.
2.
An entered threshold data code of 9 causes the
SCAN to continue regardless of signal strength.
The following procedure loads threshold data, along with the present
receiver operating parameters, into a memory channel.
Example 10 shows a typical
threshold command.
