SAFETY PRECAUTIONS

The following check should be performed for the continued protection of the customer and service technician.

LEAKAGE CURRENT CHECK

Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis
resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the
power cord is less than 460 kohms, the unit is defective.

CAUTION

Please heed the points listed below during servicing and inspection.

◎ Heed the cautions!

Spots requiring particular attention when servicing, such
as the cabinet, parts, chassis, etc., have cautions indicated
on labels or seals. Be sure to heed these cautions and the
cautions indicated in the handling instructions.

◎ Caution concerning electric shock!

(1) An AC voltage is impressed on this set, so touching in-

ternal metal parts when the set is energized could
cause electric shock. Take care to avoid electric shock,
by for example using an isolating transformer and
gloves when servicing while the set is energized, un­plugging the power cord when replacing parts, etc.

(2)There are high voltage parts inside. Handle with extra

care when the set is energized.

◎ Caution concerning disassembly and

assembly!

Though great care is taken when manufacturing parts from
sheet metal, there may in some rare cases be burrs on the
edges of parts which could cause injury if fingers are
moved across them. Use gloves to protect your hands.

◎ Inspect for safety after servicing!

Check that all screws, parts and wires removed or discon­nected for servicing have been put back in their original po­sitions, inspect that no parts around the area that has been
serviced have been negatively affected, conduct an insu­lation check on the external metal connectors and between
the blades of the power plug, and otherwise check that
safety is ensured.

(Insulation check procedure)
Unplug the power cord from the power outlet, disconnect
the antenna, plugs, etc., and turn the power switch on. Us­ing a 500V insulation resistance tester, check that the in­sulation resistance between the terminals of the power
plug and the externally exposed metal parts (antenna ter­minal, headphones terminal, microphone terminal, input
terminal, etc.) is 1MΩ or greater. If it is less, the set must
be inspected and repaired.

CAUTION

Concerning important safety

parts

◎ Only use designated parts!

The set's parts have specific safety properties (fire resis­tance, voltage resistance, etc.). For replacement parts, be
sure to use parts which have the same properties. In par­ticular, for the important safety parts that are marked z on
wiring diagrams and parts lists, be sure to use the desig­nated parts.

◎ Be sure to mount parts and arrange

the wires as they were originally!

For safety reasons, some parts use tape, tubes or other in­sulating materials, and some parts are mounted away from
the surface of printed circuit boards. Care is also taken with
the positions of the wires inside and clamps are used to
keep wires away from heating and high voltage parts, so
be sure to set everything back as it was originally.

Many of the electric and structural parts used in the set
have special safety properties. In most cases these prop­erties are difficult to distinguish by sight, and using re­placement parts with higher ratings (rated power and
withstand voltage) does not necessarily guarantee that
safety performance will be preserved. Parts with safety
properties are indicated as shown below on the wiring dia­grams and parts lists is this service manual. Be sure to re­place them with parts with the designated part number.

(1) Schematic diagrams ... Indicated by the z mark.
(2) Parts lists ... Indicated by the z mark.

Using parts other than the designated
parts could result in electric shock, fires or
other dangerous situations.

WIRE ARRANGEMENT

Press the coil down to the cable,pls
be noted to avoid the screw hole
(as round marking)

Fix the 5P line of Jack board firmly
with locking cable clip and keep the
distance with black gict cable as far
as possible,but please take attention
that it cant be closed to above

Fix the 9P line in the SD card board
with the 5P line in the USB board
with cable ties,keep the insulation
line under the flat cable

If wire bundles are untied or moved to perform adjustment or parts replacement etc., be sure to rearrange them neatly as they
were originally bundled or placed afterward.
Otherwise, incorrect arrangement can be a cause of noise generation.

VERSION UPGRADE PROCEDURE OF FIRMWARE

䎘䎑䎃

8. 6. 7.

Use the procedure described below to update the firmware to a newer version.

(1) Press the POWER switch to turn on the power.
(2) Insert a SD card or a USB device that has the update file

'dnf30XXX.bin' on the root. Put both files on the SD card or
the USB device if we provide 2 .bin files.

(3) Press the SD or USB[source] button for the input source to

be updated.

※ At this time, "V-XX.XXOK?" is displayed in the display sec-

tion. If this is not displayed, perform steps (5 )- (8 )and
check the version.

(4) If the FOLDER/TRACK jog is pressed, "Update" flashes in

the display section, and update begins. When update has
completed, the system automatically restarts.

(5) To check the current main unit version, press the MENU/

STORE button for 2 seconds. At this time, the menu list is
displayed in the display section.

(6) Turn the FOLDER/TRACK jog to select "F/W Version".
(7) If the FOLDER/TRACK jog is pressed, the current version is

displayed in the display section.

(8) Press the STOP button to exit the menu mode.

Note:

Please DO NOT touch and DO NOT disconnect power while the unit is being updated.
Before you update the unit, make sure that the power cable is firmly plugged into the DN-F300 and into an AC outlet.
If the power is turned off accidentally while the unit is being updated, the DN-F300 may not start up.

※ Please set the preset menu again after the upgrade.
