Using an AC power supply
When the AJ-B75 AC adapter is used
<Notes>
OCheck the pin signals of the DC IN socket when
using an external power supply other than the AJ-
B75 AC adapter. (DC 12 V, 8.5 A)
OPower from the AC adapter takes precedence when
both a battery pack and AC adapter have been
connected.
OWhen using the AC adapter, be absolutely sure to
first set the power of the AC adapter to ON and
then set the unit’s power switch to ON.
If the power is turned on in the reverse sequence,
the output voltage of the AC adapter will rise
gradually, and the unit may malfunction as a result.
