The data provided is believed to be accurate and applicable to the unit(s)
indicated on the cover. The research, engineering, and service departments
of YAMAHA are continually striving to improve YAMAHA products.
Modifications are, therefore, inevitable and specifications are subject to
change without notice or obligation to retrofit. Should any discrepancy
appear to exist, please contact the distributor's Service Division.
WARNING: Static discharges can destroy expensive components.
Discharge any static electricity your body may have
accumulated by grounding yourself to the ground buss in
the unit (heavy gauge black wires connect to this buss).
IMPORTANT: Turn the unit OFF during disassembly and part
replacement. Recheck all work before you apply power
to the unit.

■TO SERVICE PERSONNEL
Critical Components Information.
Components having special characteristics are marked
and must be replaced with parts having specifications
equal to those originally installed.
WARNING: CHEMICAL CONTENT NOTICE!
The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and /or plastic
(where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency
(and possibly other entities) to cause cancer and/or birth defects or other reproductive harm.
DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REA-
SON WHATSOEVER!
Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose
eyes to solder/flux vapor!
If you come in contact with solder or components located inside the enclosure of this product, wash your hands before
handling food.

■ADJUSTMENTS
1. Before Adjustment
(1)With the power turned on, wait for 5 minutes before
starting adjustment so that operation becomes stable.
(2)Adjust the OSC coil and IFT with insulated screwdriver.
(3)Set the TUNING MODE to AUTO.
(4)Decibel abbreviations
dBµ: Decibels above or below 1µV
Example :
0dBµ= 1 µv, 60dBµ= 1 mV
X dBµ= (X + 11.2) dBf
When substituting 60 for X,
60 dBµ= 72.2 dBf
2. Measuring instrument abbreviations
FM SG : FM signal generator
SSG : Stereo signal generator
AM SG : AM signal generator
DIST. M : Distortion meter
FC : Frequency counter
ACVM : AC voltage meter
DCVM : DC voltage meter
<POWER SUPPLY CHECK>
Check that the voltage obtained across each test point
and ground on the tuner circuit is as follows.
Test points Rating or Standard
+5 V terminal +5.6 ±0.5 V
-VP terminal -23.0 ±1.0 V
CAUTION :
Before setting to the TEST mode, write down the user
preset memory content in the table as shown below. (This
is because setting to the TEST mode will cause the
memory content to be the factory preset memory content,
i.e. all the user preset memory content will be erased.)

• Turn on the POWER switch while pressing the A/B/C/D/
E and FM/AM(FM/MW/LW) keys simultaneously, and
the unit enters the TEST mode for the display check.
After this, repeat (1) to (4).
(1)All the segments on the display light up.
(2)The model name, TX-396L is displayed.
(3)The place of destination is displayed.
(4)The µCOM-version is displayed.
Pressing the P1 key will cause operation to start from (1).
Pressing any other key will cause the mode to return to the
NORMAL mode.
