4. Follow the procedures of your specific transmitter to enter bind mode; the
system connects within a few seconds. Once connected, the LED on the receiver
will go solid indicating the system is connected.
5. Remove the bind plug from the BD port on the receiver before you power off the
transmitter and store it in a convenient place.
IMPORTANT: Remove the bind plug to prevent the system from entering bind
mode the next time the power is turned on.
6. After you've set up your boat, rebind the system so the true low throttle and
neutral control surface positions are set.
Failsafe
The MR3000 features Preset Failsafe that is ideal for most types of boats. With
Preset Failsafe, when the signal is lost all channels are driven to their preset failsafe
positions (normally low throttle and neutral steering). Failsafe positions are set during
the binding process (see step 3 of the Binding section).
Receiver Power Only
• When the receiver only is turned on (transmitter is off), all channels have no
output, to avoid operating or arming the electronic speed control.
After Connection
• When the transmitter is turned on and after the receiver connects to the
transmitter, normal control of all channels occurs.
• After the system makes a connection, if loss of signal occurs, Preset Failsafe
drives all servos to their preset failsafe position that was set during binding.
• When the signal is regained, the system immediately (less than 4ms) regains
control.
Receiver Power System Requirements
Inadequate power systems that do not provide the necessary minimum voltage to the
receiver have become the number one cause of radio failures. Some of the power
system components that affect the ability to properly deliver adequate power include:
• Receiver battery pack (number of cells, capacity, cell type, state of charge)
• The ESC's ability to deliver current to the receiver in electric aircraft
• The switch harness, battery leads, servo leads, regulators, etc.
The MR3000 has a minimum operational voltage of 3.5 volts.
Note: The latest generations of nickel-metal hydride (NiMH) batteries incorporate
a new chemistry mandated to be more environmentally friendly. These
batteries, when charged with peak detection fast chargers, have tendencies
to false peak (not fully charge) repeatedly. These include all brands of
NiMH batteries. If using NiMH packs, be especially cautious when charging,
making absolutely sure that the battery is fully charged. It is recommended
to use a charger that can display total charge capacity. Note the number of
mAh put into a discharged pack to verify it has been charged to full capacity.
