Description
If this message displays, the unit is at its automatic calibration limit. A service call is
recommended to ensure accurate technique and radiographic results. Exposures are
not inhibited.
This message may appear when attempting to take a high technique exposure im-
mediately after removing the unit from charge. Exposure is prevented. Operating
the field lamp or driving the AMX−4+ will assist in stabilizing the battery voltage so
that the exposure may be made.
This message may appear when attempting to expose while only a few segments
remain on the battery charge indicator. Exposure is prevented. Recharging the batter-
ies will eliminate the message and allow exposures.
The charge process is complete, and the battery is fully recharged.
The unit is charging.
All modes are disabled except drive. Service is required.
No exposures can be taken while this message appears (The length of the delay will
vary with the selected technique). This message displays while the tube anode is cool-
ing.
Displayed on the alphanumeric display any time an attempt is made to increase the
kVp above 125.
Displayed on the alphanumeric display any time an attempt is made to decrease the
kVp below 50.
If the field light is on for over 4 minutes, the light will be automatically turned off to
prevent the collimator from overheating. You may activate the field light in about 5
minutes.
Displayed on the alphanumeric display any time an attempt is made to increase the
mAs above 320 or above the acceptable energy limit for the x−ray tube anode. The
acceptable heat limit is based on the kVp you selected. Note that the kVp setting will
always take precedence over the mAs setting. That is, if the technique selected would
generate too much x−ray tube heat, the maximum mAs will automatically decrease to
permit the selected kVp.
Displayed on the alphanumeric display any time an attempt is made to decrease the
mAs below 0.40.
