Two paper clips, or equivalent, are used to
set the totalizer. Be sure totalizer is at zero
position. This position is identified when springs
T2 (Fig. 2) rest in depression on shaft. To set
totalizer:
1.
Insert one of the paper clips into the hole
located near the offset on the right end of
the shaft. (See Fig. 3.)
2. Hold the paper clip so that this end of the
shaft cannot move.
3. Insert second paper clip into one of the four
holes located in the center of the shaft.
4. Rotate clip from bottom to top until desired
setting is reached. (See Fig. 2.) The setting
is identified by the position of the offset in
relation to zero setting. Each notch (10
degrees of turn) changes the setting 5 cents.

5. When offset is rotated so that springs T1
will operate, the desired setting is reached.

Example: If totalizer were set for 10-cent
rate, totalizer would step twice. Offset on
the right end of the shaft (Fig. 4) would then
operate springs
T1
and dial tone would be heard.
