Turning the 961 off
Page 1-12
If you don't touch any key on the control head for one hour or
more, its LCD screen automatically dims to about half its nor-
mal brightness (based on its current brightness), if required by
the system. Pressing any key at any time automatically
restores the display's previous brightness level. This function
helps maintain the integrity of the display screen and reduce
power consumption when the 961 is on for many hours at a
time. It is still recommended, however, that you keep the light-
ing level low when you don't actually need it; for more details,
see "Controlling LCD-screen brightness" starting on page 3-26.
The procedure for turning off a system with two control heads
is slightly different than turning off a system with one head.
To turn off an entire system (both the head and the processor)
with one control head:
1. Press and hold the PWR key for approximately three sec-
onds, and the 961 will turn off.
To turn off an entire system (the two heads and the processor)
with two control heads that are on:
1. Press and hold the PWR key for approximately three sec-
onds until the POWER-OFF dialog box appears.
2. To turn off only one head (where you pressed the PWR
key), press the THIS HEAD key. Otherwise, to turn off the
entire system, press the BOTH HEADS key.
