After booting, long press the power on button and volume down key to bring up the automatic screenshot function. 3 In the power on state, long press the power on button for about 20 seconds to automatically reset the settings (suitable for forced shutdown and restart). ◆ Volume control keys This button is located under the power button and is used to adjust the volume. Reset hole, in the case that the machine cannot be touched or stuck and cannot be operated, the hole key can be reset and restarted by poking the hole key with a reset needle. 2.3 Icon description The three function icons at the bottom of the device screen are the menu icon, the home icon, and the back icon. ◆ Menu icon Tap under any interface and a dialog box will pop up on the screen for further action by the user. ◆ Home icon Tap under any interface to exit the function and return to the standby interface. ◆ Return to the icon Tap the icon to return to the previous menu. 2.4 Technical parameters host Size (110.5mm long×48.7mm wide ×11.4mm thick): Weight: 105.6g Lithium polymer battery Battery rated capacity: 1500mA For other relevant parameters of the battery and charger, please refer to the actual product. 3. Preparation before use 3.1 Install the SD card An SD card is a removable memory card located inside the device. Install the SD card: Carefully insert the SD card into the SD card jack, the installation is successful. Remove the SD card: Carefully remove the SD card, the removal is successful. Note: 1. The device inserted into the SD card in the boot state will not be automatically recognized, and the device needs to be turned on and off again to recognize the SD card. 2. SD card is a small object, please do not let children touch the SD card to avoid children swallowing it in the mouth! 3.2 Battery charging The lithium-ion battery supplied with this machine can be used after unpacking. Please fully charge the first three charges after the power is completely used up to allow the battery to reach optimal use. Battery level indication: ◆ Your device can monitor and display information about the battery. ◆ Normally, you can see the remaining battery level from the battery level icon in the upper right corner of the display. ◆ When the battery is low, the device will have a "low charge" prompt. If you select Tone-Warning Tone in any mode 4 in the profile, a warning tone is also emitted. ◆ When the battery is charging, a charging animation is displayed, and the charging animation stops indicating that charging is complete. ◆ It is normal for the battery to heat up slightly during charging. Note: It must be ensured that the standard voltage and frequency of the location match the rated voltage and power of your travel charger. Use of batteries Battery performance is affected by a variety of factors, including your wireless bearer network configuration, signal strength, temperature when using the device, features or settings you select and use, and accessories selected for the device and the voice, data, or other application modes you use. For optimal battery performance, observe the following rules: ◆ Only the original battery is allowed to be charged in the device to avoid injury caused by incorrect charging. ◆ New batteries or batteries that have not been used for a long time take longer to charge. If the battery voltage is low enough to turn the device on, it will take a long time for the battery icon to cha…
