Dstv EXTRA VIEW FULL KIT (DSTV FULL KIT+EXTRA HD DECODER+SMART LNB+25M COXIAL CABLE BLACK/WHITE)

Extra view works by linking one or two secondary decoders to a primary decoder. This enables the decoders to share a single subscription. But, you can only link a maximum of two secondary decoders to a primary decoder.

The primary decoder sends a heartbeat signal to the secondary decoder every 90 seconds through a communication cable or a smart LNB.

If you are living in a building that uses a single dish or a communal system then you might not have access to the smart LNB. In such a case, you can use a DStv smart switch to link your decoders.

If the secondary decoder does not receive the heartbeat signal it displays an E143 error message. But what exactly is a primary and secondary decoder?

Primary and Secondary Decoders

The primary decoder is the main decoder that has the subscription. Likewise, the secondary decoder is the decoder that shares a subscription with a primary decoder.
