The Master Antenna Preview allows the receiver to conserve its power resources
while waiting for a valid detection. If Total Scan Time is also enabled, then
further power savings can be achieved (refer to section on Enabling Total Scan
Time for details).
A Master Antenna must be defined for at least one antenna (or group of
antennas) for the Master Antenna Preview to work (refer to the section above on
Assigning a Master Antenna). If no master is designated for a particular group,
then the receiver defaults to using Frequency Priority to carry out the scan of that
group.
After the first frequency to be scanned is determined (the first one in the
frequency table), Master Antenna Preview allows the receiver to place a priority
on the appropriate Master Antenna for that frequency. When a Master Antenna
is scanned, the receiver scans only the Master Antenna for the set Scan Time. If a
valid detection is received within that time, the receiver proceeds with scanning
all applicable antennas (the Antenna Group) for only that frequency on which
the initial detection was made. When the scan is complete, the receiver moves on
to the next frequency in the frequency table, which determines the group (radio
antenna or hydrophone) that is scanned and using which master (if one is
assigned).
Several points that should be remembered about Master Antenna Preview:
• If no detection is made for the frequency and Master Antenna being scanned,
the receiver moves on to the next frequency in the frequency table. The next
frequency determines which group is scanned and using which master (if one
is assigned).
• If no master is designated for a particular group, then the receiver defaults to
using Frequency Priority to carry out the scan of that group. In other words,
the frequency is scanned on all applicable antennas for the Scan Time set and
then it moves on to the next frequency in the frequency table.
• Master Antenna Preview also works if all antennas in either a radio antenna
or hydrophone group are designated as masters. If all antennas in a group are
masters, then the receiver simultaneously scans all antennas in that group
until it receives a valid detection; then it starts scanning the group according
to its scan order.
