B： Operation Manual-New Version WIFI Clock Component Function Definition A：WIFI Clock Function Description ●When the WIFI clock gets the time, it will have the following actions： When the clock time at between 00:00~06:00,the second hands will stop at original position(12:00),At other times, the second hand runs normally, and the minute hand moves once every 10 seconds; ● When the second hand stops at original position(12:00) in the non-night stop second period and the minute hand runs normally, it is a reminder of low power (The movement will no longer automatically connect to WIFI for network time); When the three hands stop at 01:50 position, the battery needs to be replaced ( Alkaline batteries); SSID, Password unchanged, replacing the battery does not require connecting the phone Settings again; ● The WIFI clock only supports 2.4G band WIFI signals； Setup Page Description： ●There are three language available : English, Chinese, and Japanese; ● “Search WIFI” ：After clicking, refresh the SSID submenu content; ● “Reset”：Click to set the page content to the default value； ● “Save”：After clicking, the setting content is saved successfully, the WIFI clock automatically acquires network time； ● “Time Zone”：The time zone with an asterisk "*" in the Select Time Zone submenu can realize automatic daylight saving time. The place name after the time zone, not only limited to the region can use this WIFI clock, and the time zone with the same (or the same daylight saving time switch time) can use this WIFI clock; ● “NTP Server”：You can enter the time server specified by the user (only this server is used after entering the time server, and the time cannot be obtained if you enter an invalid server); If no parameter is specified, the original built-in time server is used by default. If there is no use requirement, do not enter any characters (including Spaces) in the dialog box. Otherwise, the clock cannot be connected to the network properly. Red/Blue Signal Light REC： WIFI Open Button RESET： Hands run to 12:00position Install the battery: First load the positive electrode of the battery, and then press the negative extreme. Remove the battery: Remove from the negative end of the battery. Battery holder : "AA" 1.5V LR6 alkaline battery ●REC Button +RESET Button：When the WIFI clock is working, press the two buttons for more than 3 seconds at the same time to restore the page content to the default value, and turn on the WIFI signal of clock and the WIFI signal lasts for about 30 seconds, and the WIFI clock can be searched in the WLAN list of the mobile phone (status indicator: the red light blinks). This is applicable for the scenario of operation when content changes occur. Step 2: The phone automatically pops up the setting page (Figure 2); In the SSID column, tap or enter your wireless router name. In the Password column, enter your password. In the Time Zone column, tap to set the time zone < GMT +08:00 Beijing by default >. In the Auto Adjust Time column, set the auto adjust time < 21:00 by default >, and set the frequency of the wireless router: once per day.

Note: Different WIFI clock suffixes are different. Troubleshooting and Resolution Due to certain restrictions on the openness (compatibility) of some mobile applications, the following situations may occur, and the corresponding operation methods are as follows: ● Situation 1: Example: When selecting <Wifi-Clock_697220> in the WLAN list on the phone, the setting page will not automatically pop up, but a notification will appear in the notification bar to indicate that the phone has connected to the WIFI clock. Directly selecting the notification will automatically pop up the setting page; ● Situation 2: Example: When selecting <Wifi-Clock_697220> in the WLAN list on the phone, it will display that the phone has connected to the WIFI clock, but the setting page will not automatically pop up (or will pop up an empty webpage). You need to enter 192.168.1.1 in the URL input field of the built-in browser on the phone and click "Confirm" to automatically pop up the setting page. D: WIFI clock use, simple fault confirmation and troubleshooting methods How to access the Settings page (special case) 202407 ● Failure 1: After powering on the WIFI clock, the hands run but the WIFI signal of WIFI clock does not turn on. The Wifi-Clock_697220 is not found in the WLAN list of the phone (the red light does not blink continuously, indicating that the WiFi is not turn on). Cause and solution: Low battery, replace with a new battery (use alkaline batteries). ● Failure 2: After setting and saving the settings in the settings page, …
