millitray md 500 - fuel low caution

[Jones]

flight manual says

FUEL LOW Indications: Yellow indicator ON when approximately 35 pounds of fuel FUEL LEVEL LOW (22.5 LBS usable) remain in fuel tank.

Land as soon as possible.

AND HMI2 says

FUEL LEVEL LOW warning light-on point, either 35 pounds for commercial helicopters or 70 pounds fuel remaining for noncommercial ma chines, must comply with the fuel low level caution light calibration specified in the Pilot's Flight Manual. A 70 pound fuel level low warning light calibration is not approved for commercial applications.

so  noncommercial helicopter fuel low caution light warning light-on at 70 pounds remaining

here is my question.  Is it also land soon as possible when 70 pounds remaining warning?

Refer to the specific series noncommercial/military flight manual. Maybe informational status only indication. Example Army OH-6A manual section below, even though calibration is also 35 pounds:
