Troubleshooting Poor Transmitting Range Issues
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.
• The transmitter's antenna may be partially covered by the user's fingers. Always hold the transmitter
high, approximately at shoulder height, and ensure that your fingers are not covering the antenna.
• The operating range will be somewhat lower on vehicles equipped with an aftermarket or factory
alarm.
