1. Model Name AR-M256/M316 
2. Symptom 
Abnormal noise may be produced near the power supply PWB immediately after 
turning on the power or during operation. 
3. Cause 
Abnormal noise has been produced due to resonance of the ferrite core mounted to 
the HL relay harness on the power supply PWB. 
This causes a space between the resin case for the ferrite core and the core created by 
the combination of the resin case with larger size error and the core with smaller size 
error. 
4. Description 
To prevent resonance of the ferrite core, the core holder section in the resin case has 
been padded by 0.1 mm in order not to create a space between the resin case and the 
core. Use the tie band (LBNDJ0013FCZ1) to fix the ferrite core. 
Since the same parts are also used in other places, they have been changed for 
standardization.
