After-sales Issues for Buyers

When the after-sales work order involves the specific delivery time of goods, use the work order number to contact the official after-sales hotline for progress inquiries. After the customer sends the item, the testing center usually retests it and then sends it to the factory for processing. If urgent processing is required, please promptly feedback the priority processing request to the after-sales hotline. Generally, the testing retest and factory processing need to be returned to the customer within a week.

Yes, it's normal, blue light and green light are only at 75%.

Yes, if the power is turned on after power off, the relay will restore the working status before the power off.

You need to confirm whether the socket is successfully calibrated. If successful, the voltage will show around 220V. The accuracy error after calibration is 3%-5%, which is normal within this error range.

In the format defined for the full path data transmission,typemeans data transmission modes.0X00is used to transmit the path data without the navigation path included.0X01is used to transmit the data with both the path data and the complex data included. The complex data can include path data for navigation, moving between rooms, and returning to the charging dock. The path types are differentiated by the last bits. For example, a point is four bytes in length and representsX(16 bits) andY(16 bits). The last bit of theXandYtogether indicates the type. 00: Moving between rooms. 01: Normal cleaning. 10: Returning to the charging dock. 11: Reserved.

CEL means coverage enhancement level. It is divided into three levels, with values ranging from 0 to 2, corresponding to the signal attenuation of 144dB, 154dB, and 164dB respectively. The base station and the UE will select the corresponding information retransmission times according to the CEL where they are located. 0 means regular coverage, when MCL is less than 144dB, it is consistent with existing GPRS coverage. 1 means extended coverage, which is 144dB.

The normal voltage value indicates that the voltage sampling circuit and the signal line at the back of the metering chip are normal. The current and power deviations are large, and the measurement sampling circuit at the front end and the signal wiring at the back end must be checked.
