ing of the lead-in wire to an antenna discharge unit, size of grounding con-
ductors, location of the antenna-discharge unit, connection to grounding
electrodes, and requirements for the grounding electrode. See Figure 73.1.

Precautions

1. Warranty Claim
You can find the serial number of the rear panel. In case of warranty
claim, please report this number.
2. Care
From time to time you should wipe the front and rear panels and the
cabinet with a soft cloth. For heavier dirt, dampen a soft cloth in a
weak solution of mild detergent and water, wring it out dry, and wipe
off the dirt. Following this, dry immediately with a clean cloth. Do not
use rough material, thinners, alcohol or other chemical solvents or
cloths since these could damage the finish or remove the panel letter-
ing.
