Battery Pack Insulator: To protect against possible shorts due to exposed battery holder springs, you'll need to
fabricate an insulator from the supplied piece of clear Mylar (part number E980041). Use the following steps:

Lay the Mylar over the cutting template below. Use a ruler or straight edge and a fine-tip felt pen to draw
the insulator's outline on the Mylar.

2. Using a straight edge and a sharp tool such as an Xacto knife, carefully cut out the Mylar insulator. Keep the

lines as straight as possible during cutting.

3. Install a set of AA batteries (new, old, charged or uncharged) into the holder.

4. Wrap the insulator tightly around the batteries and battery holder as shown below, forming a sleeve. The

ends will overlap approximately 1/2" (12 mm).

5. Use ordinary household transparent tape to tape the outer seam. NOTE: If you wrap the sleeve too tightly,

you may not be able to remove and install it easily. Re-position the tape slightly if necessary.

6. Remove the insulating sleeve from the battery pack. Add a second piece of transparent tape on the inner

seam. The sleeve can be re-installed on the battery pack at the appropriate point in KBT1 assembly.

Always use this insulating sleeve when installing batteries in the K1. It will protect against
accidental shorts due to the misaligned spring contacts.
