Setting
The DIP switches under the front clear cover are used
for accumulator and timer settings. As the front plate
states, the setting is the sum of the numbered switches
turned on. Any number from one to 127 can be set.
The multiply-by-ten switch must be used for numbers
from 130 to 1,270.
The easiest way to set a number is to begin with the
largest number which is less than the target, then add
smaller numbers until the target is reached. See illus-
tration at right.
Example 1: The desired accumulator count is 12. First
turn on the 8 switch, followed by the 4.
(8 + 4 = 12)
Example 2: The desired time is three minutes (180
seconds). Use 16 and 2 to set 18, then use the multi-
ply-by-ten switch to get 180.
