8. Кыйынчылыктарды

8.1 Жалпы маселелер жана чечимдер

Q: Why does the device automatically turn off after a period of time?

A: The default sleep time is 30 seconds. When your engine is turned off, the device will automatically power down after 30 seconds. You can adjust this setting by navigating to "Settings" > "SleepTimeSet" and setting a different duration.

Q: Why are my car dashboard lights or fault alarm lights lit up abnormally when using the device?

A: In some vehicles, using the A202 may cause abnormal dashboard or fault alarm lights. This can often be resolved by modifying the OBD connector. Refer to the "Product inf" > "Matching inf" section on the device for specific instructions. This typically involves carefully cutting off pins 7 and 15 on the OBD connector using needle-nose pliers to eliminate such phenomena.
