Your Rallye MAX-G™ is designed to use 12V DC power as the primary power source.
Connect the RED wire to the battery’s positive side and the BLACK wire to the ground.
There is polarity protection to prevent damage to the instrument in case the wires are
reversed, but the instrument will not work if the wires are reversed. A 1-amp fuse may be
added to protect your wiring and your instrument.
Use only robust electrical connectors. Avoid cigarette outlets or “keyed” power. Intermittent
or unreliable power may cause satellite reacquisition or a “BATT” warning and automatic
shutdown. The computer consumes very little power and will perform best if you leave it
turned on for your entire ride.
12V DC power
NOTE: When any GPS powers up for the first time, or in a new location, it can
take several minutes to receive a signal. Please be patient. During this time, a
small LED inside the GPS receiver will remain constantly on. Once a signal is
acquired, the small LED inside the GPS receiver will begin flashing.

The ICO Racing™ Rallye MAX-G™ instrument is a highly accurate, GPS-based race
computer.
For the instrument to work properly, the GPS receiver needs a clear view of the sky.
Mount the GPS receiver as close to horizontal as possible. Allow time for the GPS
to acquire a satellite fix. When you turn the Rallye MAX-G™ on, the LCD display will
flash while the GPS receiver is acquiring a satellite fix. Once the display stops flashing,
you may begin your ride.
If the GPS signal is lost during a ride, the LCD display will flash and the GPS
annunciator on the LCD will be illuminated. Keep riding. The instrument has algorithms
which will calculate the accumulated distance once a new fix is acquired. During signal
loss, the display will flash the last known distance, CAP heading, and speed.
