    Questions and Answers


    Q: I keep changing batteries is there an alternate solution? 

    A: Although it is not an SMS-branded solution, we have seen that some customers were successful with power adapters, like this one for example: Lenink AC Power Supply Adapter for 4x AA Batteries

    These should be used for both the MAIN and the SECONDARY Pearl units.
