Radio altimeter setting MCP 508

Hello,

can anyone please confirm the follwing issue with MCP 508:
Standard value for DH is 200. Klicking the on the knob in the MCP panel increases or decreases DH (displayed on the PFD).
The value is also set in offset 04FA.
BUT: When writing a value to offset 04FA (e.g. with pmFilecheck) with the MCP software running, the value immediately gets reset to the value which has been previously set via the MCP panel. When MCP software is closed, the value can be set to the desired value via the offset.

Best regards!
Michael

Solved. Bug is fixed with MCP 509.
