*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 signals may be received near the following frequencies. These are made in the internal circuit and does
not indicate a transceiver malfunction.
• 0.15 MHz • 0.23 MHz
Spurious signals may be displayed on the spectrum scope screen regardless of the transceiver's state (Tx or
Rx). They are generated in the scope circuit. This does not indicate a transceiver malfunction.
All stated specifications are typical and subject to change without notice or obligation.
