About the AC adaptor ≥ If the temperature of the battery is extremely high or extremely low, charging may take time or the battery may not be charged. ≥ If you use the AC adaptor near a radio, radio reception may be disturbed. Keep the AC adaptor 1 m (3.3 feet) or more away from the radio. ≥ When using the AC adaptor, it may generate whirring sounds. However, this is normal. ≥ After use, be sure to disconnect the AC adaptor. (If it is left connected, a minute amount of current is consumed.) ≥ Always keep the electrodes of the AC adaptor and battery clean. If you drop the battery accidentally, check to see if the terminals are damaged. ≥ Inserting a battery with damaged terminals can damage the unit. Do not throw an old battery into fire. ≥ Heating a battery or throwing it into a fire may result in an explosion. If the operating time is very short even after the battery has been recharged, the battery has worn out. Please purchase a new battery. 112 VQT3E42
