Cause and Correction
Is the DC power cord connected to AC adapter/charger?
Unplug it. If the DC power cord is connected, the AC adapter/charger will not
enter the charge status.
Is the battery abnormally hot?
Remove the battery from AC adapter/charger, leave it as is until it cools down,
and then charge it again.
Has the battery been unused for a long time?
Remove the battery from AC adapter/charger, and then reattach it.
Is the ambient temperature is too low or high?
Always charge the battery at 50 - 86°F (10 - 30°C).
Are you using the DZ-MV350A where the temperature is very low?
The DZ-MV350A can normally be used for 40 - 60 minutes with a fully charged
battery (DZ- BP14S/BP14SW), but this time will be shorter at low temperatures.
When using DZ-MV350A in a cold place, prepare extra batteries.
Battery may be dead: Replace with a new one.
The performance of battery will deteriorate if it is used for an extended period of
time or frequently.
Is the ambient temperature is too low or high?
Always charge the battery at 50 - 86°F (10 - 30°C).
The battery may be over-discharged.
Continue charging: The CHARGE indicator will change to a steady light, and
the battery will be charged normally.
Is battery charged?
Charge it.
Is Power Save specified "On"?
The specifications state that the powered DZ-MV350A automatically turns off if
it is left for as long as 5 minutes without performing recording or playback, with
"Power Save: On" specified. Set the power switch to "POWER OFF", and then
turn DZ-MV350A on again. To stop automatic power off, specify "Power Save:
Off".
Execute system reset (disconnect the battery or AC adapter/charger, and then
use a fine tipped pen, etc. to hold down the RESET button for several seconds).
Then connect a battery or AC adapter/charger and make sure the DZ-MV350A
accepts operation.
System reset will return the date/time and all items set using menu (except for
LCD settings) to the defaults at the factory. After recovery, reset the date/time
and each setting item as required.
