# Pairing Strategy (DMA-IBASE-BT-XX)

To pair the base station and the reader in a single step without considering former pairing states and using the DataMan Setup Tool, scan the Pair sticker from the scan code sticker on the base station. Place the reader in the base station.

The reader then blinks GREEN/BLUE until it gets paired with the base station (or until the end of the 20 second timeout period). When placing the reader on the base station, the base station drops its pairing with its old reader and pairs with the new reader.

Note: Scanning the Pair code puts the base station and the reader into force pairing mode. This means that the reader and the base it is put on get paired regardless of any assignments they both had previously. This force pairing mode is valid for 20 seconds after reading the Pair code.

The indicators of the base station turn GREEN to signal successful pairing:

When the reader is put onto another (unpaired) base station without any previous actions, the base station signals this event by beeping and indicators flashing RED :

The base station that is paired with a certain reader signals a bad reader alert (beeping and indicators flashing RED) also when another, unassigned reader is put into it.
