Brief description
Thank you for purchasing the QTR Window
Control Device.
For lexus sc430, this device realizes[roof open+ QTR window raised ] and[roof closed + QTR window lowered ]when the roof opening and closing operationis completed.
In addition, you can also raise or lower only
the QTR window with the roof switch. (Cannotbe done while driving)
The prototype of this device was created by
me in 2009, and has been proven trouble-free
for about 14 years. This time, I have
improved it so that anyone can easily install it
and started selling it.
In making improvements, focused onreliability and safety above all else. toimprove reliability, Specifically, adopted a
one-pack 4-channel relay to improvereliability, reducing wiring and the number ofparts. Those parts are from highly reliable
Japanese manufacturers. In addition, adopted
relays and wiring that have sufficient margin
for the motor power that drives the windows.
Furthermore, after assembly, bench tests are
performed to confirm normal operation andcomplete the product, so you can use it withconfidence.
