1. Set the speed selector to 33rpm, if speed too fast, adjusting eyelet of bottom base “33”by
counter-clockwise, on the contrary, if speed too slow, adjusting it by clockwise.

2. Set the speed selector to 45rpm, if speed too slow, adjusting eyelet of bottom base “45” by
clockwise, on the contrary, if speed too fast, adjusting it by counter-clockwise.

NOTE:

!When adjusting the speed of motor, have to adjust 33rpm first and then 45rpm.
!When adjusting the speed of 33rpm and 45rpm, pitch control UR must be set center posit.
