Adjusting the Sound Frequency of the Foghorn You can increase or decrease the sound frequency of the foghorn. The pitch of the tone will rise with an increase in the frequency, and will fall with a decrease in frequency. The minimum setting is 200 Hz and the maximum setting is 850 Hz. The default setting is 350 Hz. Regulations dictate the correct frequency of foghorns. Typically, these regulations correlate the required foghorn frequency with the size of the vessel. 1. Select the MENU key. 2. Select SYSTEM > FOG FREQUENCY. 3. Use the Channel knob to adjust the frequency in 50 Hz increments. VHF 100/200 Series Owner's Manual 11
