Load the four batteries in accordance with the polarity markings on the battery holder.
Battery Replacement Method
1
Remove the battery cover from the transmitter by
sliding it in the direction of the arrow in the figure.
2
Remove the used batteries.
Caution
If you remove the dry cell battery box from the
transmitter, replace it carefully with the wiring on the
same side as before. Reinstalling the battery box in
the opposite direction could cause the wires to be
disconnected.
3
Load the new AA size batteries. Pay very close
attention to the polarity markings and reinsert ac-
cordingly.
4
Slide the battery cover back onto the case.
Check:
Turn the power switch on the transmitter to the ON po-
sition. Check the battery voltage display on the LCD
screen. If the voltage is low, check the batteries for insuf-
ficient contact in the case or incorrect battery polarity.
Caution
Never try to recharge a dry cell battery.
The transmitter may be damaged or the battery electrolyte may leak or the battery may break.
Insert the batteries in the correct polarity.
If the polarity is incorrect, the transmitter may be damaged.
When the transmitter is not in use, remove the batteries.
If the battery electrolyte leaks, wipe off the case and contacts.
Do not use commercial AA size NiCd and NiMH batteries.
Quick charging may cause the battery contacts to overheat and damage the battery
holder.

Low Battery Alarm

If the transmitter battery voltage drops below the usable range, an audible alarm will sound
and " Low battery " will be displayed (For details, see page 189). Since the usable range of
NiMH batteries and LiFe batteries is different, the power supply used must be set by system
setting (page 181). If the battery goes dead while running (cruising), since there is the dan-
ger of collision, immediately recover the vehicle (boat) and stop running (cruising).
Warning
When a low battery alarm is generated, cease operation immediately and retrieve the model.
If the battery goes dead while in operation, you will lose control of the model.
