a network adapter, please consult your device provider to establish the desired network
connecvity.

OPERATION
Powering ON and OFF
To acvate the DT391UF, push and quickly release the Power Buon. The display will
come on in a few seconds. To put the DT391UF in Standby mode, push and quickly release
the Power Buon. To turn the DT391UF offfor extended storage, power offsafely using
any soware funcon that “shuts down computer”provided in the soware operang
system.
NOTE:
The baery packs shipped with your tablet may be low in power—please use
the AC-DC adapter with the DT391UF when seng up for the first me to fully
charge the internal baery pack.
NOTE:
When the baery pack(s) is (are) charging, the blue-colored Baery LED should
blink slowly. If plugging in the AC-DC adapter does not trigger this blinking
acvity and the LED stays dark, the baery pack(s) may have been drained
substanally. Try unplugging/ replugging the AC-DC adapter to the DT391UF a
few mes to acvate the charging process.
NOTE:
To conserve power, use (push and quick release) the Power Buon to put the
tablet in “Standby”mode while not in use. Pushing briefly on the same buon
will wake up the system within seconds.
NOTE:
Avoid using the Power Buon (“hold 4+ seconds”feature) to turn offthe
tablet—this form of hardware shutdown is intended to be a means of recovery
from lockups, and not as normal operaon.
