Refer to the User's Manual for more information.

1.2 Operating checks

1.2.1 Indicator lights for ready status and exposure

Confirm that the green (ready status) and amber (exposure) indicator lights come on on
the exposure switch. Ensure that the amber (exposure) indicator light remains on for the
whole duration of the exposure.
Additionally, check the operation of the (optional) external exposure indicator light, if the
unit is equipped with one.

1.2.2 Exposure warning signal

Confirm that the unit's buzzer comes on for the whole duration of the exposure.
The exposure switch also contains a buzzer. However, this buzzer can be enabled or
disabled (from within the exposure switch assembly) depending on local regulations. If the
exposure switch buzzer is enabled, check that it comes on for the whole duration of the
exposure.

1.2.3 Exposure switch

Confirm that the exposure switch requires continuous activation to maintain the exposure.
Releasing the exposure switch button during radiation should stop the exposure and
produce a help message.
Make a visual check and check for possible wear or damage of the exposure switch spiral
cable. Replace it if necessary.

1.2.4 Emergency stop button

Confirm that activating the emergency stop button will stop the X-ray unit operating.
Pressing the emergency stop button should block all movements of the X-ray unit, disable
radiation and produce a help message.
