Troubleshooting Poor Transmitting Range Issues
Many factors may affect the operating range of the transmitter. Some of these are:
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 metal in the car.

• The shape of the vehicle can affect range as well; vans in general have an especially poor
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
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. Holding the transmitter
• Always hold the transmitter high, approximately at shoulder height. Holding the transmitter
against your chin will also increase your range: your head acts as an antenna.
• The operating range will be somewhat lower on vehicles equipped with an aftermarket or
factory alarm.
• Windows and windshields tinted with lead or metallic tints will decrease the operating
range.
