Using
Never plug it into an outlet of other than the indicated voltage.
Plugging the charger into the wrong outlet could result in an explosion or fire.
Do not insert and remove the charger when your hands are wet.
It may cause an electric shock.
Always use the special charger or a quick charger for digital proportional R/C sets to charge a
digital proportional R/C set Ni-MH battery.
Overcharging a Ni-MH battery can result in burns, fire, injuries, or loss of sight due to overheating, breakage, or electro-
lyte leakage.
When the charger is not in use, disconnect it from the AC outlet.
Do this to prevent accidents and to avoid overheating.
Low Battery Alarm
If the transmitter battery voltage drops below the usable range, an audible
alarm will sound and "BATTERY LOW VOLTAGE" will be displayed on
the LCD screen. If the battery goes dead while running (cruising), you will
lose control of the vehicle (boat). Therefore, retrieve the vehicle (boat) im-
mediately and cease operation.
Because the low battery alarm voltage of a dry cell battery is different from
that of a rechargeable battery pack (genuine Futaba option), the type of
power source used must be set by system setting (P101).
 Warning
When a low battery alarm is generated, cease operation immediately and re-
trieve the model.
If the battery goes dead while in operation, you will lose control of the model.
