Check that a battery is installed and has charge; if the battery is missing or dead, insert a charged battery or wait a few seconds after re‑inserting it.
WMA playback and recording consume roughly twice the current of MP3 playback, which reduces battery life.
It indicates that the battery voltage is low and the player will shut down automatically; replace or recharge the battery.
