2. Countermeasures against B (Refer to Figure 10)

(1) Ensure certain distance between RF signal line and PWM-drive output line. If it’s not possible to provide space between

these lines, shield the RF signal line with a stable GND except for power GND.

(2) Same as (1), flexible cable for pickup should be shielded with GND in order to separate noise between the signal line

and the actuator drive output line.

(3) Separate the flexible cable for the motor and for the pickup.
