ProLaser III Operator's Manual
Page 22
If the APR mode is selected, all approaching vehicle
speeds will be displayed in the normal manner. However,
if a receding vehicle is targeted, the letters “Apr” are
displayed in the HUD to inform the user that the unit is in
the approaching target mode. No speeds will be displayed
on receding vehicles.
Likewise, if “REC” is selected, the letters “rEC” are
displayed in the HUD when an approaching vehicle is
targeted.
Note that a continuous, audible tone will still be
emitted when a vehicle speed is determined in a direction
opposite that of the direction mode selected.
If “Both” is selected, the ProLaser III will display
speeds for all vehicles.
Weather (WTHR) Menu
The weather feature is used to improve the unit’s
sensitivity and performance in adverse weather
conditions. Fog, rain, snow and heavy dust can
sometimes interfere with the performance of the ProLaser
III. Target ranges less than anticipated may be displayed,
typically between 50 – 250 feet. Inability for the unit to
lock a valid speed is a symptom of this problem in the
speed mode. The weather mode improves the system
performance by setting the minimum range to
approximately 250 feet. This dramatically improves both
the speed and range performance of the unit in poor
weather conditions. Note that no speed or range readings
will be possible inside 250 feet while in the “Poor” weather
mode.
When this menu item is selected the following screen
