CONTACT NAME
is a 12 character ASCII field available for displaying a phone # or name of personal who
knows 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.
SECURE LEVEL
sets LOW, HIGH or OFF modes. 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 static
viewing of configuration menus.
