DC IN socket

2 Set the power of the AC adapter to ON.

3 Set the unit’s power switch to ON.

<Notes>

O Check 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)

O Power from the AC adapter takes precedence when both a battery pack and AC adapter have been connected.

O When 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.
