Appendix C: Messages On DisplayOptima XR220amx X-Ray System 54400222-1EN Rev 1 DRAFT 11092010 C-2Operator Manual © 2010 General Electric Company. All rights reserved.Table C-1 Status message descriptionsStatus Messages DescriptionAUTO CAL LIMIT If this message displays, the unit is at its automatic calibration limit. A servicecall is recommended to ensure accurate technique and radiographic results.Exposures are not inhibited.BATTERY TOO HIGHVOLTAGE RECOVERYIS REQUIREDThis message may appear when attempting to take a high techniqueexposure immediately after removing the unit from charge. Exposure isprevented. Operating the field lamp or driving theDefinium AMX 700 willassist in stabilizing the battery voltage so that the exposure may be made.BATTERY TOO LOW This message may appear when attempting to expose when only a fewsegments remain on the battery charge indicator. This means that the batterydoes not contain sufficient charge to make an exposure.CHARGE REQUIRED Exposure is prevented. Recharging the batteries will eliminate the messageand allow exposures.CHARGE COMPLETE The charge process is complete, and the battery is fully recharged.STANDBY The unit is allowing usage for a maximum of 60 minutes (keyswitch is ON andthe unit is plugged in).CHARGING The unit is charging.DRIVES ONLY All modes are disabled except drive. Service is required.HEAT WAIT No exposures can be taken while this message appears (The length of thedelay will vary with the selected technique). This message displays while thetube anode is cooling.kVp MAX Displayed on the alphanumeric display any time an attempt is made toincrease the kVp above125.kVp MIN Displayed on the alphanumeric display any time an attempt is made todecrease the kVp below 50.LIGHT DISABLEDFOR COOLINGIf the field light is on for over 4 minutes, the light will be automatically turnedoff to prevent the collimator from overheating. You may activate the fieldlight in about 5 minutes.mAs MAX Displayed on the alphanumeric display any time an attempt is made toincrease the mAs above320 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.mAs MIN Displayed on the alphanumeric display any time an attempt is made todecrease the mAs below 0.40.DRAFT REVIEW COPYCTRL+SHIFT+F to search using Search Index (faster)
