Shipping
When shipping your Defender, please ensure that the packaging is adequate to protect the instrument. Whenever
possible, your Defender should be shipped in its original packaging or within a hard case such as a Pelican carrying
case (available for purchase from Bios). We highly recommend using a standard freight carrier (e.g., FedEx, UPS)
that supplies tracking numbers and insuring the product against damage in transit.
Bios is generally not responsible for freight costs associated with shipments to and from Bios, except in certain
instances; please contact Bios for information before initiating a shipment.
Bios is not responsible for damage that may occur during shipment.
Storage
If you need to store your Defender for an extended period, please follow these guidelines:
• Always store it in a clean, dry place.
• If possible, leave it attached to its AC power adapter/charger while in storage.
• If your Defender cannot be attached to its AC power
adapter/charger while in storage:
– Fully charge it before extended storage. If the battery isn’t fully charged prior to storage, it might be
permanently damaged.
– Fully charge it at least once every three months.
• When removing your Defender from storage, recharge the battery for at least 12 hours prior to use.
