Geo Fennel FL1000 Redback Lasers CXR880

The Geo Fennel FL 1000 HP is also sold in Australia as the RedBack CXR880 both models are very different to other laser levels on the market in that they are a fully electronic self levelling rotating laser with the addition of four vertical lines which cross on the ceiling and a plumb dot down.  The included receiver can pick up both the rotating beam or switched to pick up the vertical lines when in pulse mode.  This laser level is effectively two laser in one and can do pretty much any job in construction from concreting to site square and layout to interior visible fit out to plumbing, it does the lot.

Calibration is pretty straight forward assuming there is no damage or changes to the geometry of the vertical lines to each other or the horizontal rotation beam.

One thing to check before trying to calibrate your self is that the geometry is good, in other words that the four vertical beams are consistent to each other.  First place the laser in a darkened room and turn on all 4 vertical lines.  Look at the ceiling where these lasers cross you should see a continuous line left wall to ceiling to right wall and front wall to ceiling to back wall there should be no point where you can see two line parallel to each other, if you do then the geometry has changed and home calibration will not be possible.  If the ceiling cross is clean then you can go ahead and electronically calibrate the laser level.  See diagram below.

So now we know the geometry is good we can calibrate the laser level, calibrating the horizontal beam will automatically mean the verticals and plumb will also be calibrated, if the geometry was altered from a drop then electronic calibration alone would not calibrate all aspects of the laser level.

The top of the housing indicates The “X” Axis and “Y” axis take care lining the appropriate axis up when calibrating.  To calibrate the Geo Fennel FL 1000HP or RedBack CXR880 you will need the remote control that was supplied with the laser, if you slide down the battery cover on the remote you will see four calibration buttons one to select the axis, two for up and down adjustment and one to enter the new heights as the new calibration.

Calibrating the Geo Fennel FL 1000 and cxr880

To enter calibration mode on the laser press the “TILT” button (bottom left) and “Power” button simultaneously, then let go of the “Power” button whist still holding the “TILT” button. After a few seconds the LED lights on the control panel will flash three times indicating that the laser level is in calibration mode.  If this is not the case turn off and try again.

Now using the remote control select the axis you wish to calibrate with the “X/Y” button you will see the ‘X’ or “Y” LED on the control panel light up.  Adjust the height of the rotating beam with the “up” and “down” arrow buttons  on the calibration section of the remote.  When its the height that you have determined to be correct enter the results into the laser levels memory by pressing the “ENT” button on the remote calibration section.

HINT: I have found turning the laser off and then repeating the process for the other axis works best.  This is apposed to jumping straight into calibrating the other axis without first powering down.

As stated previously assuming the vertical lines are not out of geometry then the complete laser level should be in calibration.  You can check each vertical is consistently the same as each other and you can check plumb to make sure.

As always the Laser Level Review does not take any responsibility for your actions whilst using our guide, if you are at all unsure do not attempt to re-calibrate your laser and send it to a laser level service centre.
