16.4. Connecting the DRM0 kit for Australia for hardware type A
The DRM0 kit is required to comply with Australian Standard AS4777.2, where an external device called DRED
controls the unit through this DRM0 card.
It is only necessary to install the external DRM0 kit in hardware type A. Identify it correctly before connecting the
DRM0 kit (see section "2.2. Types of hardware").
In case of having hardware type B, where the DRMO function is factory-set without requiring an external kit, see
section "15. Connecting the digital inputs" to proceed with the connection of DRM0.
For hardware type A follow the instructions below:
1.
Disconnect the display cable from the unit.
