Solution
Solution
1. Use the handset or Gas On/ Gas Off switch to turn the gas on. 2. Reduce the peritoneal cavity pressure by venting the cannula.
Solution
7. Clear REM alarm. (Refer to generator instruction manual.)
5. Place the electrosurgical generator in ready mode. 6. Increase power levels gradually.*
1. Connect RF link or RF jumper cable to the generator. 2. Plug the three-pin connector into the Argon Gas Delivery Unit II front panel. 3. Check for proper connections at both ends. 4. Turn on the electrosurgical generator or the Argon Gas Delivery Unit II.
Solution
Solution 1. Open gas tank valves. 2. Replace gas tanks.* 3. Attach the tank transducer interface cable to the tank transducer receptacle on the rear panel. 4. Internal cables/gas lines not 4. Refer to Biomedical properly connected. Engineer or call Covidien Service Department. 5. Argon Gas Delivery Unit II 5. Refer to Biomedical malfunction. Engineer or call Covidien Service Department.
1. Both gas tank valves are closed. 2. Both gas tanks are empty. 3. Tank transducer interface cable is not attached to the rear panel.
Possible Cause
1. Place generator in spray or standard coag.* 2. Increase power levels gradually.* 3. Change flow setting.* 4. Straighten handset gas tubing. 5. Reconnect the handset to the Argon Gas Delivery Unit II. 6. Malfunctioning handset . 6. Replace the handset. 7. Eschar on the electrode. 7. Clean electrode. 8. Gas in tank is contaminated 8. Replace with 99.998% pure or not argon. or better argon gas tank. 9. Incompatible generator. 9. Use only Covidien generators specified in the Valleylab Argon Gas Delivery Unit II User’s Guide.
