5.10 SYSTEM SECURITY:
The SYSTEM SECURITY menu offers two levels of protection. A LOW level allows CAL MODE
sensor calibrations but requires the 4-digit Pass Code prior to altering menus. HIGH level locks
the entire menu database and the CAL Mode until the correct Pass Code is entered. LOW and
HIGH security levels always allow viewing of configuration menus but they may not be changed.
Contact Name is a 12 character ASCII field available for displaying a phone # or name of
personal who know the Pass Code. Lost Pass Codes may be recovered by entering the locked
security menu and holding the UP key for 5 seconds. The 4-digit code appears near the bottom
of the screen.

5.11 TECHNICIANS ONLY MENUS:
Warning: The TECHNICIAN ONLY menu group contains items that are factory
configured depending upon the type sensor and input connected to the ECO-A-X. They should
not be tampered with after installation. If configured incorrectly, some items will prevent
monitoring of target gases. Access requires a special key sequence of four consecutive UP
keystrokes to prevent accidental modification of critical items.
Troubleshoot
Response to the input should be checked and, it is recommended that a routine be developed for
maintenance checks and response of the unit. If responses are not desirable, check all wiring and
refer to “Routine Sensor Calibrations”, then perform a calibration. If this does not solve the
problem, contact the factory.
Repairs to Net Safety products should not be performed in the field. Repairs to faulty or damaged
equipment should only be performed at the factory; otherwise warranty on the product will be
voided. Refer to “How to Return Equipment” if returning equipment for repairs.
