Configuration security
Hardware switch configuration
Access to configuration is enabled only after a hardware
switch has been set. This switch is situated behind a
tamper-evident seal.
Password protection
Access to configuration levels is enabled only after the
user has entered a password:
• Calibrate level: user-assigned password
• Advanced level: user-assigned password
• Service level: factory set password
