Please make sure to turn off either the Kestrel or the HUD after using them. While both have an Auto Shutdown mode (when enabled), neither unit will turn off when connected to each other.

NK strongly recommends continual use of Lithium AA batteries in your Kestrel.  Lithium batteries respond best in extreme temperatures and help prevent against any corrosion.  Customers can also use Alkaline or Nickel Metal Hydride (NiMh) if they prefer, but we recommend turning “Auto Store” to “OFF” when placing these units in storage to minimize the drain on the battery.  Also, please make sure you set the System->Battery setting to match the type of batteries that you are using.

If possible, warm up the DROP before doing a data upload to Kestrel LiNK to help with battery life.
