When first powered up, a splash screen appears indicating the firmware revision number. After a brief
moment the System Screen is displayed.
There is a 15-minute warm-up period after power is first applied. Under “HGMS
” Monitors, "WARM UP" is
displayed. The green indicator on the HGM will blink during the warm-up period. (true?)

Setup Parameters
Before working with the HGM-MZ network, several global parameters must be defined. Most of these are
entered in the RDM Setup Screens or via the PC software. Parameters must also be defined for each
HGM-MZ monitor connected to the network. These settings serve to identify each monitor and define how
they operate. These are entered in the HGM Setup Screens. Finally, parameters must be defined for each
individual monitoring zone. These are entered in the Zone Setup Screens.
Password Protection
The HGM-RD can be password protected to prevent the unauthorized editing of setup parameters. When
password protection is enabled, an operator may still navigate between screens to observe settings or
monitor network status. The password can be alpha-numeric.
The unit is shipped with password protection OFF. Entering a password in the RDM Setup Screen #1
enables password protection. After protection is enabled, the user will be prompted to enter the password
when an attempt is made to edit a setup parameter.
After entering the password, a 30 minute time period will be allowed for entries, after which the user will again
be prompted to re-enter the password.
IMPORTANT: Please make note of your password and save it.
