THREATS
The R4BLK detects up to 4 radar band signals (threats) at a single time. The strongest
rader signal is designated as the Priority signal, and its frequency displays on the
OLED. The other 3 signals (threats) are indicated in the left side of the display. In the
following example, 3 K bands and 1 X bandfrequencies are detected.

The Priority menu setting determines which type of frequency displays on the OLED
(see page 18). If Priority is set to Signal priority, the strongest signal displays on the
OLED. If Priority is set to Ka Priority, the Ka band radar signal displays on the OLED.
USER MARKS (MEMORY POINTS)
With the R4BLK, you can mark geographical points where you commonly encounter
radar transmissions, These can be school zones, red-light cameras, and places where
police frequently monitor traffic.
When you are at the location, press MARK. The R4BLK announces "User mark
logged." Now, when you approach these points, the R4BLK announces "User mark
ahead."
Press and hold MARK at that location to delete that user mark.
The R4BLK registers up to 2,000 marks split between mute memory marks and user
marks. These marks are split at 1750 maximum and 250 minimum between the two
mark types.
USER-SET AUTO CITY SPEED
When you set speed parameters through the Auto City Speed menu in both Basic and
Expert modes, the R4BLK will change from Highway to City (or from City to Highway)
mode when the vehicle reaches that set speed. For example, if Auto City Speed is set
to 60 mph (90 km/h), driving over that limit will switch the R4BLK to Highway mode;
driving below it will switch the R4BLK to City mode.
