Interpreting Alerts
Although Solo S2 has a comprehensive warning
system and this handbook is as complete as we can
make it, only experience will teach you what to expect
from your Solo S2 and how to interpret what it tells you.
Technical Details
2120
The specific type of radar being used, the type of trans-
mission (continuous or instant-on) and the location
of the radar source affect the radar alerts you receive.
The following examples will give you an
introduction to understanding Solo S2’s warning
system for radar, laser and safety alerts.
Alert
• Solo S2 begins to sound slowly, then the rate of alert
increases until the alert becomes a solid tone. The
Signal Meter ramps accordingly.
• Solo S2 emits short alerts for a few seconds and then
falls silent only to briefly alert and fall silent again.
• Solo S2 suddenly sounds a continuous tone for the
appropriate band received. All segments in the Signal
Strength Meter are lit.
• A brief laser alert.
• Solo S2 receives weak signals. These signals may be
a little stronger as you pass large, roadside objects. The
signals increase in frequency.
Explanation
• You are approaching a continuous radar source
aimed in your direction.
• An instant-on radar source is being used ahead of
you and out of your view.
• An instant-on radar source or laser source is being
used nearby. This kind of alert requires immediate
attention!
• Laser is being used in the area. Because laser is
inherently difficult to detect, any laser alert may
indicate a source very close by.
• A moving patrol car with continuous radar is over-
taking you from behind. Because these signals are
reflected (reflections are increased by large objects),
they may or may not eventually melt into a solid
point even when the patrol car is directly behind you.
Alert
• Solo S2 alerts slowly for awhile and then abruptly
jumps to a strong alert.
• Solo S2 alerts intermittently. Rate and strength of
alerts may be consistent or vary wildly.
• Solo S2 alerts intermittently. Rate and strength of
signal increases with each alert.
• Solo S2 gives an X-band alert intermittently.
Explanation
• You are approaching a radar unit concealed by a
hill or an obstructed curve.
• A patrol car is travelling in front of you with a radar
source aimed forward. Because signals are sometimes
reflected off of large objects and sometimes not, the
alerts may seem inconsistent.
• A patrol car is approaching from the other direction,
sampling traffic with instant-on radar. Such alerts
should be taken seriously.
• You are driving through an area populated with
radar motion sensors (door openers, burglar alarms,
etc.) Since these transmitters are usually contained
inside buildings or aimed toward OR away from you,
they are typically not as strong or lasting as a real
radar encounter.
CAUTION:Since the characteristics of these alerts
may be similar to some of the preceding examples,
over confidence in an unfamiliar area can be
dangerous. Likewise, if an alert in a commonly
traveled area is suddenly stronger or on a different
band than usual, speed radar may be set up nearby.
