Please reset system before using firt time， or it could cause incorrect riding numerial value.<br />2. How to enter the system setting? There are 2 ways.<br />a. It will enter setup mode when replacing the battery， then you may set speed unit， wheel parameter， time， date， ODD etc.<br />b. In clock mode， press [MODE] key for 3 seconds to enter time setting mode. Operation is as below:When setting， press [SET] key to adjust the numerical value， press [MODE] key to set next parameter.<br />Note:<br />Please measure wheel circumference before setting circumference. There are two measuring methods.<br />1. Record marked size on wheel， refer to following table to find the perimeter.<br />2. Make a mark point on wheel， cycle the bicyle， when the marker point rolls one circle， the distance cycled is the wheel circumference ( Unit: mm )<br />3. The circumference data should be accurate， because it affects the accuracy of riding data.<br />Clear data<br />1. Pressing [SET] button for 3 seconds in the mode of DST / RTM / AVG / MAX， till LCD displays RESET letters and glitters two times， then the data shows zero， the riding data of current mode will be zero if untouch the keys.<br />2. Clear data will not affect riding distance ( ODD )， MEM data and CLK information.<br /><br /><br />                                                <br />
