most likely your device has been enabled, but was in standby mode. When you turn off the device physically has no power of piezodynamic and everything else.- During charging, spontaneously starts playing musicThe moment when the music Navigator "chooses" himself. Sometimes when charging is finished the red indicator light goes out, but the power cord remains connected, sometimes directly in the charging process. A couple of times was that the music involved just by itself when the device was turned off.
And worked there just an alarm clock, probably in the morning, hours at 9-10 am. To avoid this, I recommend to go to Alarm->alarm Mode. And using the keys "right"-"left" to navigate through the menus by day of the week and clean icons "+" by pressing "up" or "down". Now all newly manufactured devices in the default settings for all the days the alarm is off, and was formerly included except Saturday and Sunday.
must also be deactivated and a timer which can start the tune (about this in detail in the instructions).
after two years of using batteries found such a problem, and Focus on ray and Flex power. Before discharge they have greatly "failed" the stress, then restored when loading again, and after that they are discharged to the end.- Reset session, ie not play out to the end. You might think that the charge accum. low, but when you turn the power cord, the red indicator lights up... When you re-enable session to discharge accum., session play out until the endAfter charging works.
Batteries native, was only used in Navigator and only all together
Can't recommend on a new set of batteries first 3-4 cycle to carry out the discharge until the end. Avoiding "surprises" (in the form of terminating sessions) can be targeted discharge when the battery icon you will see the filling below half, after another successful class. Enough to run the session or audio file and press the "II" (stop). headset and glasses can be disabled to not interfere and the device to forget. after some time after the discharge of the batteries, the device itself will reset the playback and go into a low power mode. Then turn it off, connect the network adapter on. To begin the battery charge.
the same operation can be done on already working about a year or more batteries. Or in the device to discharge, or in a special charger that is NiMh battery can discharge before charging. You who is there. This procedure allows you to remove the memory effect, helps to increase effective capacity on used batteries.
In the device, of course, the condition of the batteries and their life is difficult to trace, given that it is NiMh. However, there are some algorithms that I will try in the future to include in the next firmware. To work out all of them and test on different batteries is of course time.<
