Balance mechanism digital display calibration
The digital display
indicates setting of the balance mechanism on a scale of 00 (minimum set-
ting) to HI (maximum setting). In the unlikely event of this system requiring calibration, proceed as
follows:
Level the platform and apply centre lock
.
fully clockwise to its maximum stop.
Press and hold the switch
for approximately eight seconds, until the digital display
shows CA. Release the switch

With the balance knob
still turned fully clockwise, press and release the switch
display will now show LO.
fully counter-clockwise to its minimum stop.
Press and release switch
.
If the calibration is successful, the display will now show 00.
If unsuccessful, Er will be displayed. Pressing the switch
again, or waiting for 15 sec-
onds, will allow the system to revert to its previous settings. Calibration may now be carried
out again.
After calibration, rebalance the head (see Balancing the head).
NOTE:
If more than 15 seconds is allowed to elapse between steps, the system will
shut down and revert to its previous settings.
