Proper Shutdown of SF-3050
To turn off the SF-3050 properly:

Press the On/Off switch on the front panel (see
Figure 39). There may be a delay of
approximately 2 seconds before the unit turns off.
Or

Switch off power to the ignition pin.
The SF-3050 will not shutdown
properly unless the external power
source is correctly connected to the
SF-3050 as displayed in Figure 38.
The connection of the ignition wire
directly to the power wire is not
recommended, and may result in the
corruption of data at shutdown of the
SF-3050.
Do not unplug the positronic end of
the supplied unterminated power
cable before switching off power to
the ignition pin. The receiver may not
shutdown properly.
