Charging the batteries
If the operating time of the SONAPHONE RD runs out, you have to
recharge the internal batteries. To start charging, you have to connect
the plug of the charger (on the right side) with the SONAPHONE RD.
After that you have to plug in the charger. The red charging lamp lights
up during charging. If the battery is completely discharged it can take 9
hours for recharging. When the charging is completed, the charging
lamp goes out and the charger can be unplugged.
An overcharging protection in the device prevents a device damage
caused by overcharging.
The charging power adaptor can also be used as power adaptor for the
SONAPHONE RD.
If the red LED charging lamp sparkles during charging, the
SONAPHONE RD has a defect and has to be sent to the manufacturer
for a check.
To improve the life of the batteries, they has to be recharged only when
the batteries are completely discharged.
