This product went through strict quality management and inspection
processes. However, misuse of electrical products could cause fire or
human casualties. Observe precautions written before use.
※ Check operation status of the product regularly.
※ Set input voltage according to season and battery status.
(e.g., Spring, Summer - 12.0V/24.0V , Winter - 12.4V/24.8V)
※ Battery efficiency may fall dramatically as battery is sensitive to external
environments (temperatures). Therefore, operation status of the connected
external device may not be constant due to battery.

may take place due to dark current. Qrontech takes no responsibility for
battery discharge.
※
±5% errors in input/output voltage may occur due to surrounding
environments (temperatures) and component errors.
※ Use fuse with rated capacity. Otherwise, a danger of fire exists.
※ In case of other malfunctions and long-term parking, turn off the switch
