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
operation is completed.
In addition, you can also raise or lower only the QTR window with the roof
switch. (Cannot be done while driving)
The prototype of this device was created by me in 2009, and has been proven
trouble-free for about 13 years. This time, I have improved it so that anyone
can easily install it and started selling it.
In making improvements, focused on reliability and safety above all else. to
improve reliability, Specifically, adopted a one-pack 4-channel relay to
improve reliability, reducing wiring and the number of parts. 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 and complete the product, so you can use it with confidence.
Note
When lifting the product, be sure to hold it by the main body, not by the
wires only.
Note
Never open the cushion protection sheet of the main unit. When opened, the
wiring may become poor contact. In that case, we cannot accept returns or
compensation.
