Transmitter Calibration; Failsafe; Low Voltage Cutoff - ProBoat Recoil PRB08022 Owner's Manual

Transmitter Calibration

The ESC has an auto calibration feature. If you rebind or
decide to use another transmitter, it may be necessary to
calibrate your transmitter to the ESC so that it learns the
transmitters throttle range.
1. Remove the propeller.
2. Ensure that the throttle trim is neutral.
3. Power on transmitter.
4. Move the transmitter's throttle lever to full throttle,
holding that position.

Failsafe

In the unlikely event that the radio connection is lost
during use, the receiver will drive the servos to their pre-
programmed failsafe positions (normally no throttle and
straight steering).
Low Voltage Cutoff (LVC)
Discharging a Li-Po battery below 3V per cell may damage
your battery.The included ESC protects the boat battery from
over-discharge using Low Voltage Cutoff (LVC). Before the
battery charge decreases too much, LVC removes power
supplied to the motor. Power to the motor pulses, showing
that some battery power is reserved for boat control and
safe landing.
Disconnect and remove the Li-Po battery from the boat after
use to prevent trickle discharge. Charge your Li-Po battery to
about half capacity before storage. During storage, make
Recoil ® 26
5. Press the power button to turn on the ESC, while holding
full throttle on the transmitter.
6. The ESC will emit 2 tones, acknowledging full throttle.
7. Return the throttle to a neutral position. The ESC will emit
one tone.
8. Move the transmitter's throttle lever to full reverse. The
ESC will emit 3 tones.
9. Return the throttle to a neutral position. The ESC is now
calibrated to the transmitter throttle range.
If the receiver is powered on before powering on the
transmitter, the receiver will enter this failsafe mode. When
the transmitter is powered on, normal control is resumed.
sure the battery charge does not fall below 3V per cell. LVC
does not prevent the battery from over-discharge during
storage.
NOTICE: Repeated operation to LVC will damage the
battery.
Tip: Monitor your boat battery's voltage before and after
boating by using a Li-Po Cell Voltage Checker (DYN4071,
sold separately).
