1 summation register, not
permanent. 1 register for constant arithmetic
(Kin, RK) 
Display 
13 digit 7 segment green VFD
(Vacuum Fluorescent Display), one digit used for sign/memory 
Special
features 
EX key swaps arguments. Switch
settings:
n 
Turns on a count number in the rightmost two digits
which counts the
numbers of calculations made 
A 
Automatically adds results to the summation register 
AM 
All entered numbers are divided by 100 for easier input
of cash amounts 
F 
Floating point mode 
0..2 
Fixed point mode with specified number of trailing
decimal digits.
Result is rounded. Does not limit the precision of the square root
function! 
%+ 
% key used for normal percent calculations 
TAX 
% key returns the value of the constants register (set
by Kin) divided
by 100 
D% 
Needs more investigation: "A + B + %" returns
100*(1+A/B) but different
things happen when substraction is involved. 
MU 
% key calculates 100*T/(100+P) where T is the first
number and P the
second one.
Ie. "20 x 5 %" returns 19.0476.
The formula can be interpreted as: What base price is needed if P
percent
added to it give a total result of T? This is sortof a reversed
percentage
calculation. 
PR 
Returns percentage of 2nd number with regard to first
number.
Ie. "40 x 20 %" returns 50 because 20 is 50% of 40.
