Step 1: Preparing a Power Source

Installing the supplied battery

Make sure that the battery is inserted before using the unit. Using the unit
powered by the AC adapter or by your computer without the rechargeable
battery may lead to the following undesirable conditions:
– When the AC power cord or the USB cable is disconnected, and the unit is
not powered for more than ten seconds, the built-in clock may be unable to
keep correct time, causing the unit to fail to play scheduled content.
– When the AC power cord or the USB cable is disconnected, the unit may
freeze.
1 Open the battery compartment cover by placing your thumb or finger on
the word "Open" on one end of the cover and pressing towards the other
end of the cover.
2 Insert the battery, label side up, aligning the metal contacts on the battery
with the contacts inside the battery compartment.
