Axle Weight Reading
The radio controller can be used to provide an approximate value for the weight
on an axle(s). Note, this is not a precise value and must be seen as an indication of
the actual weight only.
JOAB AB disclaims all responsibility if a vehicle is over weight, even if the radio con-
troller displays a value that is lower then the maximum allowed for the vehicle.
The value displayed in the radio controller will normally be within ± 150 kg.
To activate the axle weight mode, press button 12 repeatedly, until a weight scale
is shown. To select which axles are included in the measurement, press the
respective buttons: 2, 4, 6, and 8 corresponding to the axle(s) that are to be meas-
ured.
Each of the buttons (2, 4, 6, and 8) have two LEDs above them. These are used
to show which axles are selected and the status of the axles. The right LED isilluminated red for
axles that are selected, as shown. The left LED will blink red whenever an axle is 0–500 kg less
than the maximum allowed weight. The left LED will constantly illuminate if an axle is over its
allowed weight.
The LED above button 9 is used to indicate that it is the net weight that isdisplayed in the screen.
When the net weight is displayed, the LED is lit red. To change between the net weight and the
gross weight press button 9.
Charging
The charger for the radio controller is normally mounted next to the
driver's A-post inside the cab. Alternatively, it is mounted in the
driver's side toolbox, behind the door.
When not in use, always place the radio controller in its charger. This
will ensure that it is always fully loaded and ready for operation.
To remove the radio controller from the charger, first pull the bottom
out a small amount, approximately10 mm, and then push the con-
troller up, as shown.
Do not pull the controller out from the bottom. This will cause dam-
age.
