Ni-MH / Ni-Cd Battery Handling Precautions
ｌ Never plug the charger into an outlet other than indicated voltage.
Plugging the charger into the wrong outlet may result in an explosion, sparking, or fire.
ｌ Never insert or remove the charger while your hands are wet.
You may get an electric shock.
ｌ 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 cur-
rent load is applied. This may result in run-a-way or fatal crash.
ｌ Do not use commercial AA size Ni-Cd and Ni-MH batteries.
Quick charging may cause the battery contacts to overheat and damage the battery holder.
ｌ Do not short circuit the battery terminals.
A short circuit across the battery terminals may cause abnormal heating, fire and burns.
ｌ Do not drop the battery or expose it to strong shocks or vibrations.
The battery may short circuit and overheat; electrolyte may leak out and cause burns or chemical damage.
ｊ When the model is not being used, always remove or disconnect the battery.
Leaving the battery connected could create a dangerous situation if someone accidentally turns on the receiver power
switch. Loss of control could occur.
(Fail safe function)
ｊ Before running (cruising), check the fail safe function.
Check Method; Before starting the engine, check the fail safe function as follows:
1) Turn on the transmitter and receiver power switches.
2) Wait at least one minute, then turn off the transmitter power switch. (The transmitter automatically transfers the fail
safe data to the receiver every minute.)
3) Check if the fail safe function moves the servos to the preset position when reception fails.
The fail safe function is a safety feature that minimizes set damage by moving the servos to a preset position when
reception fails. However, if set to a dangerous position, it has the opposite effect. When the reverse function was
used to change the operating direction of a servo, the fail safe function must be reset.
Setting example: Throttle idle or brake position
ｊ When making adjustments to the model, do so with the engine not running or the motor discon-
nected.
You may unexpectedly lose control and create a dangerous situation.
ｊ Always check to be sure your batteries have been charged prior to operating the model.
Should the battery go dead while the model is operating, loss of control will occur and create a very dangerous situation.
ｊ To recharge the transmitter battery, use the special charger made for this purpose.
Overcharging could cause the battery to overheat, leak or explode. This may lead to fire, burns, loss of sight and many
other types of injuries.
