Troubleshooting Poor Transmitting Range

Many factors may affect the operating range of the transmitter. Some of these
are:

The condition of the battery in the transmitter.

The operating environment (for example: downtown radio-frequency
noise, airports, cellular phone towers...).

Metal: any type of metal will affect operating range. This includes the
vehicle itself.

The shape of the vehicle can affect range as well (vans in general have
less range).

The shape of the roof and A-pillars brings about considerable radio-
frequency deflection (in this case, the signal from the remote control).
As a result, the direction in which the vehicle is facing in relation to the
remote control can affect the range. Straight on (standing in front of the
vehicle) generally gives you the greatest range; the second best
performance is from the back. Using the remote control from either side
of the vehicle will usually give the lowest range.

The range will be significantly lower in a crowded parking lot than in
open space.

Always hold the transmitter high, approximately at shoulder height.

The operating range will be somewhat lower on vehicles equipped with
an aftermarket or factory alarm.
