Introduction
This manual provides the technical information necessary for
servicing the FTM-400DR/DE 144/430 MHz 50 W Dual Band
Transceiver.
Servicing this equipment requires expertise in handing surface-
mount chip components. Attempts by non-qualified persons
to service this equipment may result in permanent damage not
covered by the warranty, and may be illegal in some countries.
Two PCB layout diagrams provided for each double-sided
board in this transceiver. Each side of the board is referred to
by the type of the majority of components installed on that side
("Side A" or "Side B"). In most cases one side has only chip
components, and the other has either a mixture of both chip and
leaded components (trimmers, coils, electrolytic capacitors,
ICs, etc.), or leaded components only.
While we believe the information in this manual to be correct,
YAESU assumes no liability for damage that may occur as a
result of typographical or other errors that may be present. Your
cooperation in pointing out any inconsistencies in the technical
information would be appreciated.
Important Note
1) This transceiver was assembled using Pb (lead) free solder, based on the RoHS specication.
Only lead-free solder (Alloy Composition: Sn-3.0Ag-0.5Cu) should be used for repairs performed on this apparatus. The solder stat-
ed above utilizes the alloy composition required for compliance with the lead-free specication, and any solder with the above alloy
composition may be used.
2) Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to the instructions.

FTM-400DR/DE Technical Supplement
Alignment
ALIGNMENT-1
Introduction and Precautions
The FTM-400DR/FTM-400DE has been carefully
aligned at the factory for performance across the
specified amateur bands. Realignment should
therefore not be necessary except in the event of a
component failure. All component replacement and
service should be performed only by an authorized
YAESU representative, or the warranty policy may
be voided.
The following procedures cover the sometimes crit-
ical and tedious adjustments that are not normally
required once the transceiver has left the factory.
However, if damage occurs and some parts are re-
placed, realignment may be required. If a sudden
problem occurs during normal operation, it is like-
ly due to component failure; realignment should
not be done until after the faulty component has
been replaced.
We recommend that servicing be performed only
by authorized YAESU service technicians, who are
experienced with the circuitry and fully equipped
for repair and alignment. Therefore, if a fault is
suspected, contact the dealer from whom the trans-
ceiver was purchased for instructions regarding re-
pair. Authorized YAESU service technicians realign
all circuits and make complete performance checks
to ensure compliance with factory specifications
aer replacing any faulty components.
Those who do undertake any of the following
alignments are cautioned to proceed at their own
risk. Problems caused by unauthorized aempts at
realignment are not covered by the warranty pol-
icy. Also, YAESU must reserve the right to change
circuits and alignment procedures in the interest of
improved performance, without notifying owners.
Under no circumstances should any alignment be
attempted unless the normal function and opera-
tion of the transceiver are clearly understood, the
cause of the malfunction has been clearly pinpoint-
ed and any faulty components replaced, and the
need for realignment determined to be absolutely
necessary.

ALIGNMENT-2
Alignment Preparation & Precautions
A 100-W RF dummy load and in-line wattmeter
must be connected to the main antenna jack in all
procedures that call for transmission; alignment
is not possible with an antenna. After complet-
ing one step, read the next step to see if the same
test equipment is required. If not, remove the test
equipment (except dummy load and wattmeter,
if connected) before proceeding. Correct align-
ment requires the transceiver and test equipment
be maintained at a constant ambient temperature
between 68 ~ 86 °F (20 ~ 30 °C). When the trans-
ceiver is brought into the shop from hot or cold air,
it should be allowed some time to come to room
temperature before alignment. Whenever possible,
alignments should be made with oscillator shields
and circuit boards rmly axed in place. Also, the
test equipment must be thoroughly warmed up be-
fore beginning.
Note: Signal levels in dB referred to in the alignment
procedure are based on 0 dBμ=0.5 μV (closed circuit).
Test Setup
Set up the test equipment as shown below for
transceiver alignment. Maintain the supply voltage
at13.8V DC for all steps.
Internal System Alignment Routine
This uses a programmed routine in the transceiver
which simplies many previously complex discrete
component seings and adjustments with digital-
ly-controlled seings via Microphone buons.
To enter the Alignment mode:
1. Press and hold in the [F(MW)]and [GM)]keys
while turning the transceiver on.
2. Press the [POWER(LOCK)]key.
"LOCK" will appear in the display.
3. Press the keys of the Microphone in the follow-
ing sequence.
[0]à[3]à[4]à[0]à[3]à[4]
4. Press the [POWER(LOCK)]key.
"UNLOCK" will appear in the display.
5. The transceiver is now in the "Alignment
mode".
