Minimum Distance for Optical Communication
If you are not using the external detector(optional accessory), attach the prism unit as close as
possible to the RC-2RW. The minimum distance for optical communication is then determined by
the distance between the prism and the receiving window (dP), as described below.
Recommendation of the sealed-nickel-metal hydride (Ni-MH) battery
The use of Ni-MH batteries is recommended under low ambient temperature conditions. In
general, under cold conditions, the discharge characteristics of Ni-MH batteries are better than
those of alkaline-manganese batteries, thus providing longer operating time.
