Miscellaneous Information
FM Audio Receiver Antenna Wire
The thin loose coming out of the Rock Box is the FM radio antenna
wire. Make sure to keep this wire away from ANY power wires
to maximize radio reception. Do NOT run this wire through
handlebars or under metal surfaces. It is best to try and make sure
this wire is as out in the open as possible to maximize FM signal
strength. You may also attach another antenna onto the Rock Box
using this wire to boost FM reception.
Temperature Sensor
The Rock Box is equipped with an on-board temperature
sensor. This is identified as the shrink wrapped piece coming
out of the rear of the Rock Box next to the wiring harness.
Avoid any stress or damage to this sensor as there is a small
electrical board inside the shrink casing. Generally this
should be placed as much in the open air as possible to
ensure accurate reporting.
*WARNINGS
Always make sure the rubber covers for the AUX and USB ports are
closed when not in use to avoid collecting moisture or debris. Also
make sure to remove devices and secure the rubber door covers
when encountering any moisture to avoid damage to the unit.
Failure to follow these instructions will result in your warranty
being VOID if water enters the unit due to not properly securing
the rubber covers.
*The Rock Box output is designed for the high level input of an
amplified speaker system. Do not plug headphones into the Rock
Box or you may damage the unit.
