SUBJECT: New Logic Board and Cup Sensor Installation
MODELS: RVV NG
REASON FOR BULLETIN:
The infrared emitter that is part of the cup sensor emitter board on RVV NG venders produced before serial numbers beginning 201427PA is no longer produced. Therefore, a new emitter is in use on current-production boards, which renders these new boards incompatible with older infrared receivers and cup logic boards. For this reason, the cup logic board and cup sensor boards are now produced as one unit which must be replaced all at once. In addition, the new cup sensor emitter board requires a clear lens instead of the dark filter used with the older emitter boards. This bulletin the process for installing the new components.
