By what you are asking for can I assume that this is an external unit you can hold in your hand?
I have look on the break down of your unit for the part number you have listed ( ps282804 ) and it lists this as a access plate.
There is a part listed that might be what you are looking for but there is no picture.
The item number is 50.
The part Number is ps282163 controller assembly.
It seems that the picture and item numbers don't match.
Here is a link to the breakdown. |
