The analyzer is fitted with an internal security switch that, in combination with the ’Configuration security’ parameter settings (see
page 29), is used to prevent unauthorized access to the Configuration Level.
Two methods of configuration access protection are available:
1. Password protection (Factory Default)
The Configuration level can be accessed only when the correct password has been entered.
2. Internal security switch protection
The Configuration level can be accessed only when the internal security switch is set to the 'Enabled' position.
To access the internal security switch:
1. Switch off the power supply to the analyzer and turn the two door retaining screws

2. Using a cross-head screwdriver, remove the four cover plate retaining screws

Note. The Internal Security Switch is, by default, set to 'Disabled' and should only be used to access the Configuration level
when 'Configuration security' is set to 'Internal switch protected' – see page 29.
Do Not use the switch to access the
Configuration level when 'Configuration security' is set to 'Password protected' (default setting) unless the Password has been
forgotten. The switch overrides Password protection, enabling free access to the Configuration level.
