Errata Items:
1. Page 1, footnote 1: Change the AA cell diameter specification to 0.56" (14.2 mm).
2. Page 5, last assembly step: This step describes the installation of two self-adhesive neoprene spacers
(Figure 4). The correct location of the spacers is shown, but the figure does not clearly identify which
surface the spacers must be adhered to. The spacers must be attached to the wall of the battery bracket that
is nearest the battery on/off switch (i.e., in the plane of the drawing).
3. Page 6, fifth assembly step: Replace the existing step with the following text:

Prepare the neoprene washer by removing and discarding the inner ring. Remove the protective paper
covering the adhesive side of the washer and carefully slide the washer over the speaker magnet with
the adhesive side toward the speaker frame. (See Figure 6, next page.)
4. Page 8, fifth assembly step: Your KBT1 kit includes a 3 x 3" piece of speaker grille cloth. Cut a portion of
the grille cloth large enough to cover the speaker, and attach it to the inside top cover using tape or a long-
lasting adhesive. Double-backed transparent tape may work best. Avoid using thick tape, as this will
interfere with proper installation of the top cover.
Important Notes:
1. Cell Leakage: Damage caused to the K1 due to battery leakage or excess current drain is not covered by
the Elecraft warranty. Always remove the batteries from the K1 when not in use. Also, be sure to use an
insulator between the batteries and the battery bracket as described below.
2. Checking Battery Holder Springs: An exposed spring contact on the 8-AA battery holder could cause a
short within the battery pack. To avoid possible shorts, look closely at your battery holder's spring contacts.
If any spring protrudes beyond the edge of the plastic holder, bend it back into position using long-nose
pliers. Springs should be about 1/16" (1.5 mm) from the outer edge of the holder.
3. 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 Mylar. See instructions on the back of this sheet.
4. Battery Installation: The battery holder should be installed as shown in Figure 6 of the manual. The ends
of the batteries must face towards the front and back of the K1, not the sides. The red and black wires
should be oriented towards the left side panel of the K1 as shown.
5. Speaker Volume: The replacement speaker supplied with the KBT1 kit does not attach directly to the top
cover. Instead, it is mounted in a hole in the battery bracket. The speaker will thus appear to have very low
volume if you operate the transceiver with the cover off.
(IMPORTANT: See battery insulator fabrication instructions on back)
