FM NARROW OPERATION

While operating in FM mode, you can change the
bandwidth to narrow. The following table shows the
occupied frequency bandwidth and the maximum
modulation level. Selecting FM Narrow to match the
deviation level of other stations can avoid or eliminate any
distortion of the received audio and any denterioration of
the communication legibility.
Occupied Frequency

REDUCING THE DEFLECTIONS OF THE
S-METER FOR USE IN FM-MODE
You can configure the sensitivity of the S-meter to be
used in FM mode by selecting either "High", allowing
the S-meter to function in the same manner as that
for past HF transceivers, or "Low", which reduces the
S-meter sensitivity by an expansion of the dynamic range.
Selecting "Low" to reduce the S-meter sensitivity enables
the deflection of the S-meter to be as the same deflection

as the S-meter used in other modes.
