PREPARATIONS BEFORE DRIVING
Checking standby mode
At the time of shipment, the standby
mode is as shown in the figure on the
right. Each LED has the following
meaning.
[Important] Safety feature for driving in reverse
On radio controlled cars, the same throttle controls are used for braking and
driving in reverse. This can cause car to move backward when the intention is to
apply the brakes. Suddenly trying to reverse the motor while it is rotating forward
can place severe stree to the gears, motor, and ESC, sometimes resulting in
internal damage. The XARVIS XX is equipped with the following feature to
prevent this.
After applying the brakes, before reversing, the ESC will wait 1 second or more
for the throttle to return to neutral and for the the motor to go from rotating in a
forward direction to coming to a complete stop (it will not go into reverse within
the span of 1 second).
This feature prevents unintentional reversing even if the reverse drive feature is
set ON on the ESC. It prevents damage to the drivetrain of the car and potential
collision with other vehicles, as well as many other possible problems, and is
essential to allow short braking action when turning corners.

Stanby mode at time of shipment
This completes the preparation before driving. Connect the motor and enjoy
driving.
When using lithium polymer batteries, set the cutoff voltage before driving to 3.2V/cell (1
recommended)(P.16)
Verifying the transmitter positions have been correctly set to their initial settings
The standby LED (see below) should be the only one
illuminated
when the throttle is in
the neutral, maximum forward, and maximum reverse (brake) positions. If the Stanby
LED is
unlit
in all other positions, the initial setup has been completed properly.
(The standy LED is the only LED that alternately illuminates and goes out when
adjusting the throttle)
If the standby LED does not follow this lighting pattern, the initial setting was not
completed properly. Make sure the throttle related adjustment on the transmitter
are initialized and the RX cable is properly connected to the receiver. Then, retry
the initial setting procedure.
※
Depending on the configuration of the vehicle,
the car may move in reverse
when the throttle
is operated in the forward direction. If your car displays this behavior,
change the rotation
direction of the motor
(P.16).

Note, this safety feature cannot be disabled. However, as detailed in [Reverse
drive ON/OFF and motor rotating selection](P.16), when configuring to
crawleroriented settings, vehicle movement that occurs once the throttle is
placed in the brake position will be specialized for reverse driving (the brake
will not work), thus disabling this function.
①
※
LED<green> :
Factory shipped condition = unlit
If the
battery voltage becomes lower than the cutoff voltage
(P.16) while
driving, the green LED will blink and the car will drive at extremely low
speeds. If this occurs,
replace the battery
.
②
LED<blue> :
Factory shipped condition = lit
Standby LED when setting mode (P.10) is in ESC mode. Unlit during Link
mode.
※
Under "ESC Mode", <blue> LED will be blinking if the program selected
(P.12) is "Boost/Turbo Disabled", or both "Full Boost Timing"(P.17) and "Full
Turbo Timing" (P.19) are disabled.
②
LED<red> :
Factory shipped condition = unlit
Standby LED when setting mode is in Link mode. Unlit during ESC mode.
※
Under "Link Mode", <red> LED will be blinking if the program selected (P.12)
is "Boost/Turbo Disabled", or both "Full Boost Timing"(P.17) and "Full Turbo
Timing" (P.19) are disabled.
②
LED<orange> :
Factory shipped condition = lit
Illuminated when the reverse drive feature (P.16) is set to ON.
Unlit when set to
OFF.

※
If the ESC heats up to temperature limits while driving, the motor will remain
at low speed and the Orange LED will blink.
If this situation occurs,
discontinue operation until the ESC temperature drops back to ambient
temperature.
If the Orange LED starts blinking after driving for only a brief
period of time,
check to see if the gear ratio settings are overloading the
motor.
