Test Method and Procedure

NOTE

To ensure the network connection is normal, please place the phone within 15 meters of the access point

(AP) and no obstacle exists between the phone and AP.

Set AP correctly, switch on the phone and place it within the transmitting range of AP.

Touch the Menu key, and select System settings > WLAN > On > Scan.

After the service set identifier (SSID) of AP is found automatically, touch it and enter the

password to connect the phone to the network.

Adjust the distance between the phone and AP to observe the change of Wi-Fi network

signal strength.

When the network connection is normal, start the web browser and access a website to

test the network quality.

If the test is successful, stop the Wi-Fi test. If the test fails, repair the phone again or

send it to the advanced maintenance center.

Install the user identification module (UIM) card.

Press the Power key to switch on the phone.

When the network connection is normal, check whether the change of the phone signal

strength is within a specified limit.

Dial a fixed line to conduct a voice call and test the voice quality.

If the test is successful, stop the voice call test. If the test fails, repair the phone again or

send it to the advanced maintenance center.
