Power is normally applied to the 1 RPM run motor. Each hour, from HH:58:05 through HH:58:59, power is removed from the run motor and applied to the fast advance motor. During manual clock corrections, power is applied to both motors for 4 minutes and 15 seconds. See Figure B-12.

TYPE 10—Simplex 45th Minute, Dual Motor

Power is normally applied to the 1 RPM run motor. Each hour, from HH:44:05 through HH:44:59, power is removed from the run motor and applied to the fast advance motor. During manual clock corrections, power is applied to both motors for 4 minutes and 15 seconds. See Figure B-12.
