Mode description:
On the main page, press and hold the upper right button for 2 seconds to enter the mode setting page, press and hold the upper right button for 2 seconds to exit the setting page and return to the main page.
Mode 1 - Lead Acid P setting.
Mode 2 - Ternary Lithium L setting.
Mode 3 - Fe Lithium F setting.
Mode 4 - Custom High and Low Voltage Settings: Custom Low and Saturation Voltage, display 00.0000, left number is low voltage parameter, right number is saturation voltage parameter.
Mode 5 - Backlight setting: Display 5-b, short press the button in the lower right corner to turn on/off. On means the backlight turns off automatically after 10 seconds, Off means the backlight is always on.
Mode 6 - Low voltage alarm setting: display 00.0VLo, on the left is the alarm voltage parameter (alarm will sound if the voltage is lower than this parameter)
Mode 7 - Alarm sound setting: Display 7-A, short press the button in the lower right corner to turn on/off. ON turns on the audible alarm feature, OFF turns off the audible alarm feature 

Notice:
About the difference between two types of lithium batteries (ternary lithium L and ferrous lithium F).
The battery is fully charged. The saturation voltage of the ternary lithium battery string is DC4.2V, and the saturation voltage of the ferrous lithium battery string is DC3.6V.

Packaging Includes:
