Programming tips
If you are having difficulty programming
the integrated remote control, here are
some helpful tips:
앫
Check the frequency of hand-held re-
mote control
5
(typically located on
the reverse side of the remote). The in-
tegrated remote control is compatible
with radio-frequency devices operating
between 288-399 MHz.
앫
Put a new battery in hand-held remote
control
5
. This will increase the likeli-
hood of the hand-held remote control
sending a faster and more accurate sig-
nal to the integrated remote control.
앫
While performing step 3, hold
hand-held remote control
5
at differ-
ent lengths and angles from the signal
transmitter button (
2
,
3
or
4
) you
are programming. Attempt varying an-
gles at the distance of 2 to 5 inches
(5 to 12 cm) away or the same angle at
varying distances.
i
If you sell your vehicle, erase the codes of all
three channels.
