you enable WEP/WPA/WPA2 encryption (or advanced alternatives) for secure access.

• hen WEP/WPA/WPA2 is enabled, you may need to consult your network admin-

istrator or your networking equipment literature to properly conﬁgure associated
settings such as Authentication mode, etc.

OPERATION

Powering ON and OFF

come on in a few seconds. To put the DT391UF in Standby mode, push and quickly release
the Power Button. To turn the DT391UF oﬀ for extended storage, power oﬀ safely using

NOTE:

The battery packs shipped with your tablet may be low in power—please use
the AC-DC adapter with the DT391UF when setting up for the ﬁrst time to fully
charge the internal battery pack.

NOTE:

When the battery pack(s) is (are) charging, the blue-colored Battery LED should
blink slowly. If plugging in the AC-DC adapter does not trigger this blinking
activity and the LED stays dark, the battery pack(s) may have been drained
substantially. Try unplugging/ replugging the AC-DC adapter to the DT391UF a
few times to activate the charging process.

NOTE:

To conserve power, use (push and quick release) the Power Button to put the
tablet in “Standby” mode while not in use. Pushing brieﬂy on the same button
will wake up the system within seconds.

NOTE:

Avoid using the Power Button (“hold 4+ seconds” feature) to turn oﬀ the
tablet—this form of hardware shutdown is intended to be a means of recovery
from lockups, and not as normal operation.
