NOTE
The normal operating range
of the transmitter is approx.
200 ft (61 m). However, this
distance can be affected by
the following conditions.
Depending on where you park,
you may experience reduced
range reception. Interference
can be caused by any of these
conditions:
1. Proximity to buildings and
automobiles.
• Large trucks parked nearby
• Concrete walls
• Underground parking lot
2. Proximity to high power transmitters (television, radio,
cellular, HAM radio, etc.).
3. When your transmitter is carried together with such
communication devices as a cellular phone, a walkie-
talkie, or a notebook computer.
4. When the transmitter is in contact with or covered by
a metallic object.
5. When the vehicle contains aftermarket window tint.
6. When another remote engine starter is used nearby.
7. When the battery becomes weak, the remote control
range becomes short.
8. In some cases the remote transmission range can be
6410120B
200 ft (61 m) longer than the reception range. Therefore the engine
can be started/stopped, and the remote status may
not be displayed.
Vehicle construction and the surrounding
environment cause reflected waves that may interfere
with the low power RF signal transmitted by the
remote control. This interference may result in "dead
spots" around the vehicle; places where remote
control signals will not be accepted by the main unit.
