Power and battery issues

Battery will not charge

  • The battery is overheated, or too cold.

    The battery will charge between 0 °C and +40 °C (+32 °F and +104 °F). If you have been using or storing the battery and/or device in a particularly hot or cold environment, the battery may be outside the safe charging temperature range. Sensors in the battery will prevent the battery from charging until its temperature returns to a normal level.

  • The battery is not installed correctly.

    If the battery is not installed correctly in the device or the battery charger, it may not have a proper connection and will not charge.

  • The battery terminals are dirty or corroded.

    If the terminals of the battery are dirty or corroded, it may not have a proper connection and will not charge.

Device will not start up

  • The batteries do not have enough charge to power the device.

    Press and hold the charge indicator button on each of the batteries. At least one charge LED must be lit up to indicate that a battery has enough power for the device to start on battery power. If no LEDs light up on a battery, attach the device to an external power source, or swap the batteries for charged batteries, then try again.

  • The batteries are not correctly installed.

    The device may not be receiving power from the batteries if they are not installed properly. Remove both the batteries, then replace them correctly.

Device suddenly turns off during use

  • The device may have run out of power and gone into critical suspend mode.

    If your battery charge level gets too low, the device will automatically go into a hibernate mode to prevent loss of data. Check the battery level by pressing and holding the battery level button on each of the batteries. If the battery charge is too low, connect the device to external power, or swap the batteries for a charged batteries.

    If you regularly run out of battery power while in the field, consider carrying spare batteries with you. The device supports hot-swapping of the batteries. Swap one battery at a time; you must always have one battery with sufficient charge in the device while you remove a battery and replace it with another. If you remove both batteries, the device shuts down.
