Programming tips
If you are having difficulty programming
the integrated remote control, here are
some helpful tips:
Check the frequency of the hand-held
remote 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.
Put a new battery in the hand-held re-
mote control 5. This will increase the
likelihood of the hand-held remote con-
trol sending a faster and more accurate
signal to the integrated remote control.
While performing step 3, hold the
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.
