Transmitter Ni-MH Battery
When purchasing a transmitter Ni-MH battery as a spare, etc., use the following:
Part name
NT5F1700B (6V/1700mAh)
Please do not use the transmitter's battery, HT5F1700B, as the receiver's battery.
Since the transmitter's battery has an overload protection circuit, the output power will
be shut down when the high current load is applied. This may result in run-a-way or fatal
crash.

For a description of how to install the battery holder to the transmitter, see "Ni-MH Re-
placement" on page 18.

The method to dispose of used dry cell batteries depends on the area in which you re-
side. Dispose of the batteries in accordance with the regulations for your area.
