on for the time interval equal to the MAS selected divided by 100. All exposures with the AMX I! will be
at 100 milliamperes. Therefore, exposure time may be determined by dividing the MAS selection by 100.
For example, if 300 MAS is selected, the lamp will glow for three seconds or if 2.0 MAS is selected it will
glow for 0.02 seconds.
During the time that the X-Ray lamp glows, there will also be an audible tone signal to indicate that x-rays
are being produced. At the low MAS selections, this signal will be a short beep. For longer exposures there
will be a sustained tone.
WARNING: | If either the X-RAY lamp glow or the tone signal continues longer than 3 seconds under any
circumstances, immediately release handswitch ROTOR and X-RAY buttons and turn the
main power circuit breaker OFF.
In such a case, another exposure should not be attempted until the unit has been examined by a qualified
x-ray serviceman.
The Vertical Column supports the telescoping arm, x-ray tube unit and collimator. It rotates in a bearing
structure in the base of the unit.
To rotate the vertical column, move the telescoping arm to the desired position. 360° of movement
is possible. A friction brake holds the vertical column in place. If the column drifts after positioning,
call for service.
The VERTICAL ARM LOCK, Illustration 1-4, will secure the telescoping arm in any position. If the arm
drifts when the lock is released, call for service. If the counterbalance system should fail, a safety device.
locks the arm in position, and the unit must be serviced before it can be used again.
