Starting the test cycle

Ä The program enters test cycle mode. The LED above the T key
lights up. Only the exposure program number appears on the
digital display. None of the LEDs above the patient symbol keys
light up.
2. Press the exposure release button.
Ä The test cycle is started.
3. Wait until the test cycle has been completed.
4. Press the T key again.
Ä The program exits test cycle mode.
5.1.3.2 Releasing the exposure
The exposure can be released using the release button on the spiral
cable or the remote control. If the unit is installed in an X-ray room,
which features a door edge, and the line of sight towards the patient is
guaranteed, the exposure is to be released via the remote release, see
"Using remote release" [→ 87].
WARNING
The unit emits X-ray radiation.
Excess exposure to X-rays is detrimental to health.
➢ Use the prescribed accessories for radiation protection.
➢ Do not stay in the X-ray room during exposure. Move as far away
from the unit as the coiled cable for the release button allows you
to.
CAUTION
The movement of the system may be adversely affected by the
patient's physical constitution, clothing, or dressings, or by
wheelchairs or hospital beds.
The exposure is automatically terminated if the movement of the unit
is inhibited. The exposure must be repeated.
➢ Ensure that the movement of the unit is not impaired when
positioning the patient. Before the exposure, perform a test cycle
using the T key.
CAUTION
Prematurely letting go of the release button cancels the exposure
immediately.
The exposure must be repeated.
➢ Take care not to let go of the exposure release button
prematurely. Press the release button until the end of the
exposure. Note that radiation may be released several times
during an exposure cycle.
