Honeywell vx6 Reference Manual page 170

For a VX6, the User Idle state turns off the display backlight. There is no System Idle mode so the VX6 remains in User Idle
mode until the Suspend timer expires or a primary event occurs.
The Device Status tab displays the status of power managed devices. Note that since the VX6does not support power
management, all devices show the "high" power level. There are no user options on this screen.
There is no Suspend mode on the VX6. If the Suspend timer is enabled, the VX6 will shut down when the Suspend timer
expires.
