The NS-P320 is composed of the NS-M104, the NS-C104, the NS-E104 and the SW-P201.
The NS-M104, the NS-C104 and the NS-E104 loudspeakers are not field serviceable and must be replaced as complete units.
IMPORTANT NOTICE
This manual has been provided for the use of authorized YAMAHA Retailers and their service personnel.
It has been assumed that basic service procedures inherent to the industry, and more specifically YAMAHA Products, are already known and understood by the users,
and have therefore not been restated.
WARNING: Failure to follow appropriate service and safety procedures when servicing this product may result in personal injury, destruction of expensive
components, and failure of the product to perform as specified. For these reasons, we advise all YAMAHA product owners that any service
required should be performed by an authorized YAMAHA Retailer or the appointed service representative.
IMPORTANT: The presentation or sale of this manual to any individual or firm does not constitute authorization, certification or recognition of any applicable
technical capabilities, or establish a principle-agent relationship of any form.
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
1. Critical Components Information
Components having special characteristics are marked Z
and must be replaced with parts having specifications equal
to those originally installed.
2. Leakage Current Measurement (For 120V Models Only)
When service has been completed, it is imperative to verify
that all exposed conductive surfaces are properly insulated
from supply circuits.
●Meter impedance should be equivalent to 1500 ohm shunted
by 0.15µF.

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 REASON 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.

■SW-P201 DISASSEMBLY PROCEDURES
(Remove parts in the order as numbered.)
1. Removal of Front Grille
The front grille is fixed to the cabinet with dowels
at 6 locations.
* As a screwdriver (for slotted head screw) is used
for removal, use special care not to cause damage
to the cabinet.
a. Using the screwdriver inserted in the gap between
the front grille and the cabinet (bottom side first),
push up the front grille.
b. Remove the front grille by lifting it up.
When installing the Front Grille, apply quick-drying
bond to the dowels and then fit them into dowel holes
for secure installation. (The Front Grille will come off
easily if its dowels are fitted into dowel holes only.)
2. Removal of Rear Panel
Remove 14 screws ( q) in Fig. 2.
* Arrow marks ( ) are printed to identify the screws to be
removed. q
Fig. 2
Fig. 1
* When assembling the Rear Panel, check to ensure that
the packing is not damaged so as to prevent air leakage
from occurring.
