Remote control transmitter control
To set the Yamaha Security System, the user aims the remote control transmitter at the watercraft
and presses the lock or unlock button to remotely turn the Yamaha Security System relay ON or
OFF. The unlock button can also be used to remotely select the normal mode or L-MODE.
(1) Turning the Yamaha Security System relay ON/OFF:
The remote control transmitter sends an encoded radio wave signal to the receiver when the
lock and unlock buttons are pushed. The antenna of the receiver receives this signal. If the ID
code matches a registered ID code, the receiver transmits a signal to turn the Yamaha Security
System relay ON and a lock/unlock signal to the ECM to enable/disable starting of the engine.
(2) ECM engine startability control:
The ECM prevents the engine from being started until the ID code from the remote control trans-
mitter is verified and the signal to enable the engine to be started is received.
(3) Normal mode/L-MODE:
If the unlock button on the remote control transmitter is pressed continuously for more than 4
seconds, the transmitter sends a mode-switching signal to the ECM to switch to the normal
mode or L-MODE.
