4.5 SECURITY SWITCH

The ONICON F-4200 features a security switch that prevents changes to program settings when

enabled. The meter is shipped with this security switch disabled so that the user can recall and

install the saved “site.” It is strongly recommended that this switch be moved to the enabled

position once the meter is fully operational.

IMPORTANT NOTE

With the security switch enabled, you can still navigate through the programming menus, but

you cannot change any of the settings. A “SECURITY” message will appear on the LCD display to

indicate that the security switch is enabled.
