Unscrew the cover of the battery compartment and open it.

    Remove the rechargeable batteries.

    Take the charged batteries out of the loops on the hip belt or out of the battery charger.

    Observe the polarity, and insert rechargeable batteries (2x AA) into the battery compartment.

Do not insert rechargeable batteries together with single-use batteries. Single-use batteries could otherwise leak and damage the transmitter.

Do not insert batteries with different capacities. This would damage them.

    Close the battery compartment cover and screw it into place.
