• 1. Help cyclists automatically detect the wheel size when they are not sure of the wheel size, and use the speed sensor smoothly;

• 2. After turning on the [Auto-detection] function, turn on the recording of riding under the outdoor GPS positioning, and the iGS630 will automatically detect the wheel size value after 5-10 minutes.

• 3. This function is set on the sensor detail page after connecting the "speed sensor", "speed cadence sensor" or "E-bike";

NOTE: This function is enabled by default when “speed sensor” and “speed cadence sensor” are connected, and disabled by default when “E-bike” is connected.

Preparation before using the function

What to prepare:

1. Prepare any one of "speed sensor", "speed cadence sensor" or "E-bike" with sufficient power;

2. Ensure that the GPS signal of the outdoor cycling route is stable after the [Auto Detection] function is turned on.

How to use the function

How to use (take the "speed sensor" setting page as an example)

• 1.After the device is connected to the speed sensor, the [Auto Detect] function is enabled by default, and the wheel size cannot be edited at this time;

• 2.Turn on the record ride after the outdoor GPS positioning is turned on to record the ride. After 5-10 minutes, the iGS630 will pop up the wheel size automatic detection pop-up window (display the detected wheel size)；

• 3.The pop-up page will show the options of [Update] and [Ignore]:

①Select [Update], the device will update the wheel size to the detected size, and calculate the speed and distance according to this wheel size;

②Select [Ignore] and the pop-up window disappears;

③If you do not select it, the pop-up page will disappear automatically after 10 seconds, and the detection pop-up will pop up again after 5-10 minutes.

TIPS:

1. When the device detects that the wheel size changes within +-0.5%, there will be no pop-up prompt;

2. The wheel size can only be edited after the [Auto-detection] function is turned off.
