Rofis R2 modes with eneloop - resolved

I purchased this light in the recent sale on Amazon. I was checking it out with a rechargeable NiMh today, and found it only has low and medium modes, no high. The literature that comes with the light shows what I would interpret is high for 1 minute, then step down.

Did I miss something here, or does the light not have a high mode with non lithium rechargeable. I tried an eneloop and a duracell NiMh, same result with both. Even double click does nothing. Strobe modes work. moonlight works. Just no high mode. Was considering buying some lithium primaries, but having second thoughts . . . .
