Elecraft KX3 Application Note – Installing the Speaker Grille Cloth Page 9 of 9
Set the top and bottom parts of the KX3 next to each other as shown in Figure 1, and then reconnect the flex
connector and battery cables. Orient the flex cable as shown, with the longer tab at the connector pointing toward the
speaker. Route the battery cable away from the flex cables so they do not interfere when the case is closed.
Replace the batteries (if used). Before installing each cell, sheath around the cell for damage. The sheath
provides critical insulation to avoid short circuits. Many cells, especially single-use (not rechargeable) alkaline cells,
have the entire cell casing connected to the positive terminal which is separated from the negative terminal at the
bottom end of the cell by a thin insulator (see Figure 14). If the plastic sheath is damaged, the spring contact in the
battery holder can bridge the insulation, shorting the cell. The resulting heat can do extensive damage to the KX3.
Damage to the sheath along the sides of the cells can also cause short circuits by touching the metal shield on the
battery retainer.

Close the case and tighten all four thumb screws.
This completes the installation of the speaker grille cloth.
