FUNCTION 4: COMPASS MODE
The RXB-IV is equipped with a compass to allow for instantaneous
determination of direction as well as distance to an object.
ACTIVATING THE COMPASS MODE:
To use the compass feature of the RXB-IV, it is necessary to activate
compass mode by pressing MODE until the degree symbol is flashing,
then pressing POWER until the icon and the word “ON” is displayed.
CALIBRATING THE COMPASS:
Before using the compass for the first time at different places,
it is necessary to calibrate the RXB-IV in order to obtain a realistic
database and detect more accurate related azimuths.
To calibrate the compass for horizontal direction reading:
1.
Press MODE until the degree symbol is blinking, and press
POWER to activate the compass mode.
2.
Continue through the menu options selecting the unit of
measure and preferred reticle.
3.
After selecting the type of reticle, “dEC” will flash. Press the
MODE button repeatedly until the proper declination angle is
displayed. The numbers will start at the current declination
angle (Ø if this is the first time setting this feature) ascending
until 30 is reached. After 30 has been reached, the next number
displayed will be -30, continuing to ascend each time the MODE
button is pressed. Press the POWER button to select the
appropriate
declination
setting.
4.
After the declination angle has been set by pressing POWER, “CAL”
will begin flashing, indicating it is time to calibrate the compass.
5.
To calibrate the compass, press POWER while “CAL” is flashing.
The number “1” will flash briefly, then display steadily. While “1”
is displayed steadily, rotate the RXB-IV one full revolution around
the Y-axis. Once this has been completed, press the MODE button
again, causing the number “2” to flash briefly, then display steadily.
While “2” is displayed steadily, rotate the RXB-IV one full revolution
around the Z-axis. Once this has been completed, press the MODE
button again and the RXB-IV has been properly calibrated.
The Leupold Green Ring RXB-IV is designed to be as easy to
operate as it is effective. However, there are times when minor
troubleshooting may be required.
UNIT DOES NOT TURN ON – OLED DOES NOT ILLUMINATE:
• Depress POWER button for more than one (1) second
• Check battery; replace if necessary
Troubleshooting
DISTANCE READING CANNOT BE OBTAINED:
•
Make sure that the POWER button is being depressed
(as opposed to MODE button)
•
Make sure that nothing, such as your hand or finger, is blocking
the objective lenses — as this could interfere with the emission
and reception of the laser pulses
•
Make sure unit is held steadily while depressing the POWER button
•
When using BOW mode, it is important to note that TBR returns
are limited to 60 yards (55 meters); returns greater than 60 yards
(55 meters) will be displayed in the LOS display
CHANGING BATTERY:
Changing the CR-123A battery is a simple operation on the RXB-IV.
The battery chamber cover is located on the underside of the unit
on the left-hand side. To change the battery:
1. Lift the battery chamber cover handle.
2. Twist the handle counterclockwise by one quarter of a turn.
3.
Pull the handle away from the RXB-IV and the battery
chamber cover will open.
4. Remove the old battery.
5. Insert the new battery (positive “+” end down).
6.
Replace the battery chamber cover, paying attention to align
the lugs of the cover with those inside the chamber.
7.
Twist the handle clockwise by one quarter of a turn to lock
the cover into place.
8. Fold the handle back down to keep it out of the way.
NOTE:
Batteries should be removed when exhausted or when the
RXB-IV will not be used for more than 10 days.
CLEANING THE LENSES:
When removing dust on the lens surface, use a soft oil-free brush.
When removing stains or smudges like fingerprints from the lens
Care and Maintenance
surface, wipe the lenses very gently with a soft, clean cotton cloth
or quality, oil-free lens tissue. Use a small quantity of pure alcohol
(not denatured) to wipe stubborn smudges. Do not use velvet cloth
or ordinary tissue, as it may scratch the lens surface. Once the cloth
has been used for cleaning the body, it should not be used again
for the lens surface.
CLEANING THE MAIN BODY:
Clean the body surface with a soft, clean cloth and a dry cloth. Do not
use benzene, thinner, or other organic agents because they may cause
discoloration or rubber degeneration. Do not use alcohol for cleaning
the main body.
STORAGE:
It is always recommended that when the RXB-IV is not in use that it is
stored in the case provided.
Water condensation may occur on the exterior lens surface during
periods of high humidity. Therefore, store the RXB-IV in a cool, dry
place. After use on a rainy day or at night, thoroughly dry it at room
temperature, then store in a cool, dry place.
Do not leave the RXB-IV in a vehicle on a hot or sunny day, or near
heat-generating equipment, as this may damage or negatively affect it.
