Section 13 Warranty, liability and complaints The manufacturer warrants that the product supplied is free of material and manufacturing defects and undertakes the obligation to repair or replace any defective parts at zero cost. The warranty period for instruments is 24 months. If a service contract is taken out within 6 months of purchase, the warranty period is extended to 60 months.
Warranty, liability and complaints To avoid or limit consequential damage, it is therefore recommended to design the control loop such that a malfunction in an instrument results in an automatic change over to the backup control system; this is the safest operating state for the environment and the process.

Appendix C Passcode editor For applications requiring compliance to FDA 21 CFR Part 11, certain device functions must be protected with passcodes. Passcodes can be changed in the passcode editor. If passcode protection is not required, use the preset passcodes (Table 20). To activate the passcode editor: 1. Press CONF. 2. Enter 1989, the administrator passcode. The initial screen will show for approximately 3 seconds, then proceed to the next function. 3. Use the ARROW keys to change the passcode. 4.
Passcode editor 1 Not available with si792x C-PA Important Note: The passcode editor cannot be accessed without the administrator passcode. Record changes in a secure location. It is not possible to override this system if the passwords are lost. The unit must be exchanged. Contact technical support for assistance.
