Tokyo HiPower (THP) discontinued the HL-50B model (design never approved by FCC) and replaced it with the FCC certified HL-45B model. The manual for this model is NOT on the THP web site, the HL-45B may be close enough for guidance.

Ham Radio Outlet (HRO) Stores in North America are the USA distributor (and support) for THP.
