*The LCD display may have cosmetic imperfections that appear as small or dark spots. This is not a malfunction
or defect, but a normal characteristic of LCD displays.
Spurious may be received near the following frequencies. These are made in the internal circuit and does not
indicate a transceiver malfunction.
• 0.150 MHz • 10.490 MHz
