a radio frequency subject to Federal Communications
Commission (FCC) Rules and with Industry Canada.
This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than

use this equipment.
At times you may notice a decrease in operating range.
This is normal for any RKE system. If the transmitter
does not work or if you have to stand closer to
your vehicle for the transmitter to work, try this:
Check the distance. You may be too far from your
vehicle. You may need to stand closer during
rainy or snowy weather.
Check the location. Other vehicles or objects may
be blocking the signal. Take a few steps to the

re-coded to match the new transmitter.The lost transmitter will no longer work after the new
transmitters are re-coded. The vehicle can have a
maximum of eight transmitters matched to it. See

The RSE includes two 2-channel wireless headphones
that are dedicated to this system. Channel 1 is dedicated
to the video screen, while Channel 2 is dedicated to
RSA selections. These headphones are used to listen
to media such as CDs, DVDs, MP3/WMAs, DVD-As,
radio, any auxiliary source connected to A/V jacks, or

this section for more information.
Infrared transmitters are located at the rear of the
RSE overhead console. The headphones shut off
automatically to save the battery power if the RSE
system and RSA are shut off or if the headphones
are out of range of the transmitters for more than
