Instrument repairs are only to be performed by the manufacturer or qualified service personnel. Only accessories and supplies either delivered by or approved by Roche are to be used with the instrument. This ensures the performance and measuring accuracy of the unit.
The instrument is not suitable for operation with a direct current power supply. Use only the original mains plug delivered with the cobas b 221 system. The use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
Use only slightly moistened cloths or cotton sticks to clean the instrument. Disinfectants Use only liquid disinfectant such as protein remover (Roche deproteinizer) or an alcohol-based (about 70%) surface disinfectant. Do not spray disinfectant directly onto the instrument because this could cause malfunctions in the electronics.
1 Safety information cobas b 221 system ESD protection measures ESD protection measures ESD = Electrostatic Sensitive Device Explanation of the phenomenon The most frequent cause of electrostatic discharge is friction of various materials such as plastic, synthetic fiber, hard rubber or paper.
221 system 1 Safety information ESD protection measures Why is ESD protection so important today? Formerly, current controlling semiconductors were mostly used (TTL, normal transistors, etc.). Today the principle of current logic is virtually the only technology in use in MOS and CMOS components.
