alarms from any of a number of stations he might service in a
given market.
First,
StationRotation
must be turned on by setting
Enable:
to
On
.
This will inhibit manual tuning, graying-out the manual
Tuner
setup section completely. Next the
Rotation Time (Sec):
is pro-
grammed, and this takes some planning.
When the 552 tunes to an HD Radio program, it takes about
eight seconds to acquire, buffer and begin delivering the pro-
gram audio. This is not a consideration for analog-FM-only
broadcasts, but if even one HD program is included in the
Pre-
set Stations
listing, then timing must be set for a minimum of 30
seconds, maybe 60 seconds to be absolutely sure.
There are additional alarm setup considerations when using the
StationRotation feature. 552 alarms generally have time-
on/time-off settings that will directly impact the
Rotation Time
(Sec):
setting. See the
Alarms
discussion beginning on Page 38.
The on/off times may be quite different between normal single-
station and StationRotation operation.
The
Status:
display gives a second-by-second countdown of ro-
tation time.
Keep in mind:
all the audio outputs will reflect StationRotation
operation. Always ask yourself, “Who’s hearing this?”
FM LEVEL METERING
The

Webpage displays metering for all FM signal
measurements.
FM Carrier
Modulation
These three bargraphs and the associated numerical readouts
to their right give quasi-peak-response measurement of FM car-
rier deviation. The integration time for this measurement is set
by the
