RX DC X-RAY UNIT
7.1 Setting the safety unlock mode
The RX DC x-ray unit has a safety unlock for the ball joint.
The default setting allows the ball joint to be disengaged by simply touching one of the keys present on the front of the
head. To prevent accidental contact with the keys from unexpectedly disengaging the ball joint (and therefore causing
undesired movement of the head), the safety unlock mode can be activated. In this mode, the ball joint is disengaged
only if both keys are activated at the same time.
To set the safety unlock mode, press keys and to go to the set up menu. Scroll the parameters up to
parameter P05 and press key . Scroll the options to select “ON” and press key Press key to quit the
set up menu.
7.2 Setting the operating mode
X-ray unit features the following operating modes:
• AUTO: the system automatically selects the best setting available for each tooth-patient size combination
• USER: the system automatically proposes the optimum exposure time according to the selected tooth and patient size - En65:
all exposures are performed at 65KV and 6mA.
For both operating modes, the exposure time is in the range 0.02s - 1s. The permitted anode voltage and current
combinations are shown in the following table:
