clArifier
You may change the receiving frequency only without
changing the transmit frequency.
Here is the technique for utilizing the Clarier:
1. Rotation of the [CLAR] knob will allow you to
modify your initial offset on the y. Offsets of up to
±9.995 kHz may be set using the Clarie.
nOTe:
Even when the clarier is disabled, the variance
of the clarier remains (both TX and RX frequencies).
diAl locK
Pressing the [Power / LOCK] button toggles the
locking of the [MAIN DIAL] knob and some switches,
to prevent accidental frequency changes.
advice:
You may select the locking schemes via the menu item
“Lock Mode”.
Att (AdjuSt the receiviNG SeNSitivity)
You may reduce the receiving signal strength to 20 dB when extremely strong local signals or high noise
degrade reception. You may optimize the characteristics of the receiver front-end, for best reception,
depending on the noise levels and the signal strengths.
Press the [ATT] button several times to set the desired
selection.
NoiSe blANKer (iNterfereNce rejectioN)
The FT-410 includes an effective Noise Blanker, which can signicantly reduce noise caused by automotive

AGc (tool for comfortAble ANd effective receptioN)
The AGC system is designed to help compensate for fading and other propagation effects, with
characteristics that can be of particular value on each operating mode. The basic objective of AGC is to
maintain a constant audio output level once a certain minimum threshold of signal strength is achieved.
Press the [AGC] button repeatedly to select the desired
receiver-recovery time constant. For most operations,
we recommend the “AUTO” mode.

Auto Sets the receiver-recovery time automati-
cally depending on the operating mode.
Fast Sets the receiver-recovery time to fast.
This mode is suitable for CW/DATA recep-
tion.
Slow Sets the receiver-recovery time to slow.
This mode is suitable for SSB/AM recep-
tion.
nOTe:
Normally, the “Auto” selection is satisfactory for most situations, but in the event of operation on a crowded
band where you wish to receive a weak signal, you may wish to change the setting (to FAST, for example).
A B C
Shift (iNterfereNce rejectioN)
IF Shift allows you to vary the DSP lter passband higher or lower, without changing the pitch of the incoming
signal, so as to reduce or eliminate interference. Because the carrier tuning frequency is not varied, there is
no need to re-tune the operating frequency when eliminating the interference.
Rotate the [SHIFT] knob to the left or right to reduce
the interference.
Referring to Figure “A”, note the depiction of the IF DSP
filter as the thick line, with the [SHIFT] knob in the 12
o’clock position. In Figure “B”, an interfering signal has
appeared inside the original passband. In Figure “C”, you
can see the effect of rotating the [SHIFT] knob to reduce
the interference level by moving the lter passband so that
the interference is outside of the passband.

rf GAiN
The RF Gain controls provide manual adjustment of the gain levels for the receiver RF and IF stages, to
compensate for noise and/or signal strength conditions at the moment.
The [RF/SQL] knob should, initially, be rotated to the
fully clockwise position. This is the point of maximum
sensitivity, and counter-clockwise rotation will gradually
reduce the system gain.
advice:
As the [RF/SQL] knob is rotated counterclockwise
to reduce the gain, the S-meter reading will rise.
Rotating the [RF/SQL] knob control to the fully
counter-clockwise position will essentially disable the receiver, as the gain will be greatly reduced. In this
case, the S-meter will appear to be “pegged”. (That is a full-scale reading).

Note:
The receive-mode CLARIFIER functions normally while using this frequency, but variation of the transmit
frequency is not possible. Activation of “EMG” does not enable any other out-of-amateur-band capability
on the transceiver. The full specications of the FT-410 are not necessarily guaranteed on this frequency,
but power output and receiver sensitivity should be fully satisfactory for the purpose of emergency
communication.
In an emergency, note that a half-wave dipole cut for this frequency should be approximately 45’3”
on each leg (90’6” total length). Emergency operation on 5167.5 kHz is shared with the Alaska-Fixed
Service. This transceiver is not authorized for operation, under the FCC’s Part 87, for aeronautical
communications.
