1. Measure to establish uniformity of the operations control PWB.

1.Model Name: AR-280/285/335

2.General: A change in the form of supply of each type of PWB was reported in Technical Report

No. ARE-121, but the new operations control PWB (units not attached to the operation flash PWB) is the same part, and therefore the part code has been made uniform regardless of model type or market destination.

2. Change in the attachment location of the grounding terminal carried out as a measure to improve operationability.

1.Model Name: AR-280/285/335

2.General: A change has been carried out in the attachment location for the grounding wire of the
