Prior to Applying AC Power to the Console
Please read this section before applying AC power to the console.
Security Code Enable/Disable
Access to all setup functions through either the front panel and/or the RS-232 interface can be restricted by the
use of security codes. Once this feature has been activated, only persons knowing the user-designated codes may
enter or change any setup values.
This feature will prevent unauthorized persons from intentionally or accidentally entering or changing setup values.
Two separate Security Codes may be entered—one to restrict access to the Setup Mode from the front-panel
keyboard and another to restrict remote access through the RS-232 interface.
Open the left front panel door and locate the slide switch for the battery and the DIP switch. See appropriate
figure for your console (Figure 4-1 - Figure 4-3).
