If the system has been stored for more than 60 days, a warm-up period is necessary for ion removal from the image intensifier tube. Leave the system ON with no operation for 4 hours. Press any C-Arm control panel key to continue.

If the system has been in storage for more than 6 months, the batteries need recharging. X-rays are disabled. Leave the WorkStation power cord plugged in, make sure the interconnect cable is properly connected, and wait 24 hours before use. The system does not need to be turned on to recharge.

The analog-to-digital channels are checked during system start-up. If a fault in the data conversion process is detected in any of the channels, the system will not operate. Perform the error recovery steps. If the problem persists, call a qualified service person.

This message alternates with the technique displayed on the control panel display and an alarm sounds. The anode temperature is at 80% of its rated heat capacity or greater. The alarm may be disabled by pressing the ALARM RESET switch on the control panel. Continued use without cooling may damage the x-ray tube. Although fluoroscopy is not prevented, you should wait for the tube to cool before making another exposure. HLF and film exposures are not allowed. WARNING: When the ANODE IS HOT - XX% message displays, personnel should avoid bodily contact with the X-ray tube. Do not allow the X-ray tube housing to contact the patient.

This message will alternate with the technique displayed on the control panel display. Anode temperature is at 70% of its rated heat capacity or greater. You may continue with fluoroscopy, but discretion is advised. WARNING: When the ANODE IS WARM -XX% message displays personnel should prevent all bodily contact with the X-ray tube.

This message is displayed as the system prepares the technique for a film exposure. If the X-ray switch has not been pressed after 60 seconds the message will be removed from the display.

If the effective battery charge drops to between 70 to 40 percent, this message will alternate with the technique displayed on the control panel display. FLUORO, FIL and HLF exposures are still allowed. To charge the batteries, leave the system plugged into an AC receptacle with the interconnect cable in place between the C-Arm and the WorkStation. The WorkStation power switch should be turned to the OFF position. Normally, a full battery recharge requires only a few hours. If the batteries are further discharged without adequate recharge time, the effective charge may drop below 70 percent.

If the effective battery charge drops below 40 percent, this message will alternate with the technique displayed on the control panel display. The WAIT message appears in the center of the technique display. Exposures are allowed in FLUORO mode but FILM and FLF exposures are not allowed until the battery has recharged. To charge the batteries, leave the system plugged into an AC receptacle with the interconnect cable in place between the C-Arm and the WorkStation. The WorkStation power switch should be turned to the OFF position.

If the battery charger fails at boot-up this error is displayed and the system will not operate. Perform the error recovery steps described at the beginning of this chapter.

CAUTION: Continuing system operation when the COL IRIS TOO LARGE message is displayed may result in over exposing the patient due to a larger than indicated field size. Complete the current procedure if necessary, then call for service.

The iris collimator motor control cannot maintain position tolerance. This message alternates with the technique displayed on the control panel display. You may continue to use the system, although the iris instability may degrade the image aat the edges of the X-ray field. Complete the current procedure if necessaary and then call your service representative.

This message alternates with the technique displayed on the control panel display. The collimator iris motor is unable to open or close the collimator iris. You may continue to use the system, although you will not be able to adjust the collimator iris. Complete the current procedure if necessary and then call your service representative.

The HLF (High Level Fluoro) or Digital Cine exposure has exceeded the preset time interval and has been terminated. The time interval parameters are dependant on the pulses per second selected. This safety precaution discourages excessive continuous lengths of time in HLF mode. This message remains displayed until the footswitch is released.

This message alternates with the technique displayed on the control panel display and an alarm sounds. The housing temperature is aat 80% of its rated heat capacity or greater. The alarm may be disabled by pressing the ALARM RESET switch on the control panel. Although fluoroscopy is not prevented, you should wait for the tube to cool before making another exposure. HLF and Film exposures are not allowed at this temperature. CAUTION: Continued use without cooling may damage the X-ray tube.
