Fig. 1 TM Elapsed time is measured from start to current point, in units of hours, minutes and seconds. At 10 hours, it returns to zero and counting begins anew. With Reset operation, it returns to zero. AVS Average Speed 0. 0 - 65. 0mile/h ±0. 3 mile/h AVS The average speed from start to current point is displayed within 27 hours 46 minutes 39 seconds (99, 999 seconds) or 999. 99 miles (km). If either is exceeded, (. E) is displayed and calculation ceases.

When pressed in stop state in each mode, the following can be revised. · In ODO mode ------------------ Wheel circumference · In mode -------------------- 12-hour clock · In TM, DST or AVS mode --- On/off the Auto function Reset Operation: (Fig. 2) Select any mode except ODO, then press M button and S/S button simultaneously. (When done in ODO, registered wheel circumference will be displayed. ) All Clear Operation: (Fig. 3) When M button, S/S and set buttons are pressed simultaneously, all data stored (ODO, speed scale, Wheel circumference and clock time) is erased. All displays illuminate, then mile/h symbol illuminates. This should only be executed after replacing battery or when irregular display occurs due to static electricity, etc. Since all memories are erased, set necessary data again according to "Main Unit Preparation". With Reset operation, it returns to zero and counting begins anew. 12-hour clock time The current time is displayed by a 12-hour clock. 0:00' - 11:59' ±0. 003 % AUTO (AUTOMATIC START/STOP) FUNCTION DST AUTO Reset Operation Fig. 2 All Clear Operation Fig. 3 This function switches the main unit to start or stop automatically, in which AUTO symbol appears on the screen, and you are free from pressing S/S button each time.

(1) How to measure wheel circumference (L) of your bike (Fig. 4) Put a mark on the tire tread and ride the bike one full wheel revolution. Mark the start and the end of the revolution on the ground and then measure the distance between the two marks. Or, the "Setting Values Cross Reference Table" tells you an approximate circumference according to tire size. (2) Setting Speed Scale Preform all clear operation. Then mile/h alone will be displayed as illustrated in fig. 5. Km/h and mile/h are alternately displayed with each press of S/S button. [. . . ] ----- Is the distance between sensor and magnet too far?----- Are the marking line of the sensor and the center of magnet matched each other?----- Refer to "Sensor/Magnet Mounting" and re-adjust correctly. ----- Replace the Bracket & Sensor part with a new one.
