Please note that the #389170 XMS01MG XRAY Micro Servo is an analog servo and therefore it is required and necessary that you set your radio transmitter
to Standard Response Mode, not High Response Mode. If you set your radio to High Response Mode (or similar), you run the risk that the servo electronics
will become damaged, possibly resulting in servo failure. For more information about setting up your radio, please see the instruction manual supplied with
the radio.
Some servos may get into contact with the central
aluminum layshaft and this can brake the free action
of the transmission. It is suggested to slightly modify the
servo holder.
Use a sharp hobby knife and remove the edge of the
servo holder as shown.

Safety Precautions:
• Practice using the hobby knife before making this modifi cation.
• Wear safety glasses and gloves.
• Perform this modifi cation in a safe area away from small children.

WARNING!
•This product is not suitable for children except under the direct supervision of an adult.
• First-time users should seek advice from people who have experience with RC cars and who have properly installed and used electronic speed
controllers.
• Never leave your model unattended with the battery connected.
• Be sure that your operating frequency is clear before turning on or running your model, and never share the same frequency with somebody else at the
same time. Ensure that others are aware of the operating frequency you are using and when you are using it.
• Always turn on your transmitter before you turn on the ESC or connect the battery pack. Always turn off the ESC or disconnect the battery pack before
turning off your transmitter.
• Immediately after using your model, do NOT touch the model’s electronic equipment, as it may be hot.
• When you connect the battery and turn on the electronics, make sure your car is physically prevented from moving or getting away from you and causing
damage.
• Technical faults of mechanical or electrical nature may cause the motor to jump into motion unexpectedly, which can cause serious damage or injury.
• All cables and connectors must be effectively insulated. Short circuits can ruin your ESC, servo, or battery pack.
• Use only polarized connectors for ESC connections.
• Do not reverse the polarity of the ESC connections.
• If a fault should occur, this could cause a fi re in the model and threaten anything in the vicinity.
• Do not allow any metal part to short circuit the batteries, ESC, or other electrical/electronic device on the model.
• The ESC is designed exclusively for use in battery-operated radio-controlled models. No other usage is permissible.
• Like all electronic components, the ESC must not be exposed to water or fi re.
• Do not stall the motor. The ESC will fail within seconds if power is applied to the motor when the car cannot move.
• When the motor is connected to the ESC, do not connect a separate battery to the motor to run it. This will damage the ESC and invalidate the
warranty.
• This speed controller is NOT waterproof.
• Always make sure that enough air can get to the speed controller so that good cooling conditions are achieved.
