In this modification we took into account all “advantages” of soviet manufacturing (one should not make bent casings, very dense mounting, little “bumps” on the electrodes and electrodes of such complicated shape and many other “should notís”).
Casing was made of ABS plastic with straight section line between the upper and lower parts of the casing.
Electrodes were reduced to three metal strips (“three pathways”).
Buttons relocated from the side to the top of the casing. All the rest operating controls remained the same.
Power supply: replaceable accumulator which could be charged from both solar battery and charging unit.
