    Connecting DC Power

    1. Connect the cable from the Shure PS50 power supply to the DC power supply input.
    2. The white LED will illuminate when the PS50 is connected to an AC power source.

    Inserting and Removing Bodypack Batteries

    To Insert:

    1. Align the battery with the key-way of the charger bay.
    2. Press the battery into the charging bay until it locks into place.

    To Remove:

    Press the release tabs on the sides of the battery and pull back.

    Inserting and Removing Handheld Batteries

    To Insert:

    1. Slide the battery into the charging bay.
    2. Press the battery until it locks into place.

    To Remove:

    1. Press the release button on the front of the charger module.
    2. The release mechanism will eject the battery from the charger module.

    Charging Batteries

    Slide the battery into the charging bay until it locks into place. Charging begins as soon as the batteries are inserted.

    Charge Status LED

    Each charger bay has an LED to indicate the status of the battery.

    Red

    battery charging
    Green

    charging complete
    Off

    battery inserted incorrectly or battery depleted below 3.0 volts.
    Amber

    charging stopped at reduced capacity (not less than 75% capacity) because the battery is too warm. To reach 100% capacity, a battery must be cooled to below 45°C.

    Recovering a Battery from Deep Discharge

    A deeply discharged battery is one that has been discharged to less than 3.0 volts. When the charger detects a deeply discharged battery, it automatically enters recovery mode, which charges the battery using a reduced current. A red LED indicates recovery mode. If recovery is successful, the charger exits recovery mode and charges the battery to capacity. If the battery cannot be recovered in less than 30 minutes, the red LED turns off and charging stops.

    Changing the Charger Module

    The modular design of the charger housing accepts either the AXT901 handheld charging module or the AXT902 bodypack charging module. Use the following instructions to change the charging module.

    Caution! Remove DC power and remove batteries when installing the charging module.

    1. Remove the 4 mounting screws that secure the charging module.
    2. Pull the charger module to remove it from the housing.
    3. Insert the replacement charger module into the housing (note the orientation of the guide rails).
    4. Insert the mounting screws (4 pieces) and tighten them to secure the charging module.

    Troubleshooting

    Power LED off.

    DC power fault - check connection to power supply. Ensure PS50 power supply is connected to an AC power source.

    Charge status LED does not illuminate.

    Battery is not fully inserted.

    Battery does not charge

    Battery discharged below 3.0 volts. Try another battery.
