Standby button & LED indicator
Th
e front panel Standby button will toggle the preamplifi er between
operate, its fully operational state, and a standby mode that leaves the
preamplifi er off , yet ready to respond to system commands via any of the
supported control options (e.g. IR input, DC trigger, CAN-Bus, or
RS-232).
Th
e current state of the preamplifi er is indicated by the LED indicator in
the center of the standby button. When the unit is powered and switched
on, the state of this LED indicates the following:
• on
= standby
• fl ashing (on power-up) =
initialization
• off
=
operate
• on (dim) =
display timeout
• fl ashing (after power-up) =
AC mains voltage out of range
If you are planning not to use the preamplifi er for an extended period of
time, e.g. vacation or other travel, we suggest you disconnect it from the
AC mains. Please be certain that the preamplifi er is turned off prior to
disconnecting it from the AC mains.
Also, it is a good practice to physically disconnect any and all valuable
electronics from the AC mains during electrical storms, as a lightning strike
anywhere near your home can put a tremendous surge on the AC mains
that can damage any piece of electronic equipment, no matter how well
designed and protected. Th
e best protection in the case of severe electrical
storms is simply to remove the electronics from any connection with the
power grid.
