FUNCTIONS
SPD: Current Speed
0.0 – 199.9 Km/h or 120.0 Mile/h +/- 1%
The current speed is always displayed on the 4 digits set when riding.
DST: Trip Distance
0.00 – 999.99 Km or Miles +/- 0.1%
The DST function accumulates the distance data from the last RESET operation as long as the bicycle is
being ridden.
CLK: 12HR Clock
It displays the current time on a 12HR clock.
TM: Riding Time 0H00M00S - 19H59M59S
The TM totals the riding time from the last RESET operation.
AVG: Average Speed
0.0 – 199.9 Km/h or 120.0 Mile/h +/- 0.1%
1. It is calculated from the DST divided by the TM; the average data counted is from the last RESET to current points.
2. It displays an "Err" symbol when either the TM is over 100 hours or the DST is over 1,000 km (or miles).
Reset the unit in order to restart.
MAX: Maximum Speed
0.0 – 199.9 Km/h or 120.0 Mile/h +/- 1%
It shows the highest speed from the last RESET operation.
TTM: Total Riding Time
0H00M – 1999H59M
The TM totals the riding time from the last ALL CLEAR operation.
ODO: Odometer
0.0 – 19999.9 Km or Miles +/- 0.1%
The ODO accumulates the total distance as long as the bike is moving. The ODO data can be cleared by the
ALL CLEAR operation only.
