FeinTech FeinBeam TxRx Instruction Manual page 21

All the paired device information in RX mode will be deleted after power on. Please don't switch
between TX or RX mode immediately in 3 seconds after unit has turned off, because the device may
still have power and mode switching may be ignored.
Note: If the device works as a Bluetooth transmitter, the memory is limited to 4 device records for
performance reasons. An entry will be overwritten by the latest paired device. The unit supports an
automatically reconnection function. The reconnection time depends on the number of stored pair-
ing records (From 7 seconds for the unit has 1 paired record to 22 seconds with 4 paired records)
