AVR-3310CI/AVR-3310/AVR990/AVC-3310
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, un-
plugging 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.
◎Only use designated parts!
The set's parts have specific safety properties (fire resis-
tance, voltage resistance, etc.). For replacement parts, be
sure to use parts which have the same properties. In par-
ticular, for the important safety parts that are marked zon
wiring diagrams and parts lists, be sure to use the desig-
nated parts.
◎Be sure to mount parts and arrange
the wires as they were originally!
For safety reasons, some parts use tape, tubes or other in-
sulating 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.
◎Inspect for safety after servicing!
Check that all screws, parts and wires removed or discon-
nected for servicing have been put back in their original po-
sitions, inspect that no parts around the area that has been
serviced have been negatively affected, conduct an insu-
lation 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. Us-
ing a 500V insulation resistance tester, check that the in-
sulation resistance between the terminals of the power
plug and the externally exposed metal parts (antenna ter-
minal, headphones terminal, microphone terminal, input
terminal, etc.) is 1MΩor greater. If it is less, the set must
be inspected and repaired.
Concerning important safety
parts
Many of the electric and structural parts used in the set
have special safety properties. In most cases these prop-
erties are difficult to distinguish by sight, and using re-
placement 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 dia-
grams and parts lists is this service manual. Be sure to re-
place them with parts with the designated part number.
(1) Schematic diagrams ... Indicated by the zmark.
(2) Parts lists ... Indicated by the zmark.
Using parts other than the designated
parts could result in electric shock, fires or
other dangerous situations.
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.

WIRE ARRANGEMENT
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.

CAUTION IN SERVICING
Before the Digital P.W.B. are replaced
If you cannot specify the cause of the digital PWB defect, carry out "Initializing" →"Update to latest firmware".
The defect may be cleared.
・See the following for the method of initializing the μcom.
Initializing AV SURROUND RECEIVER
AV SURROUND RECEIVER initialization should be performed when the µcom, peripheral parts of µcom, and Digital P.W.B.
are replaced.
1. Switch off the unit.
2. Hold the following STANDARD button and DSP SIMULATION button, and switch on the unit.
3. Check that the entire display is flashing with an interval of about 1 second, and release your fingers from the 2 buttons and
the microprocessor will be initialized.
Note:・If step 3 does not work, start over from step 1.
・All user settings will be lost and this factory setting will be recovered when this initialization mode.
So make sure to memorize your setting for restoring after the initialization.
JIG to use for servicing
When you repair the printing board, you can use the following JIG. Please order to Denon Official Service Distributor in your
region if necessary.

ERROR MODE(displaying the protection history)
When started up, the error information is displayed.
Starting up:
With the "MENU" and "STATUS" buttons pressed, press the "ON/OFF" button to turn the power on. The error (protection
history display) mode is set.
Then, press the "STATUS" button to turn on the FL display.
2.2. About the display on the FL display
When the "STATUS" button is pressed after setting the error (protection history display) mode, a history like the one shown
below is displayed, depending on the conditions.

2.3. Clearing the protection history
There are two ways to clear the protection history, as described below.
(1) Start up the error (protection history display) mode, display the error, then press and hold in the "ENTER" button for 3
seconds.
Press and hold in the "ENTER" button for 3 seconds
The above is displayed and the protection history is cleared.
(2) Initialize.

VERSION UPGRADE PROCEDURE OF FIRMWARE
You can update by downloading the latest firmware from the Internet.
1.Update from the Internet
1.1. Connecting to the Network
(1) System Requirement
• Internet Connection by Broadband Circuit
• Modem
• Router
• Ethernet cable (CAT-5 or greater recommended)
(2) Setting
1.2. Check for Update and Update
Check if the latest firmware exists. You can also check approximately how long it will take to complete an update.
(1) Press the MENU button on the remote control to display the GUI menu.
(2) Use the cursor buttons to select "Manual Setup" →"Option Setup" →"Firmware Update" →"Update Check".
(3) Press the ENTER buttom.
• The latest version of the firmware uploaded to the web is displayed.
• If the latest firmware version is on the web, proceed to (4).
• If the latest firmware is already installed, press the MENU button to close the menu.
(4) Use the cursor buttons to select "Update", then press the ENTER button.
• During update, the power indicator lights red and the GUI screen is shut down. And a rough remaining time is
indicated on the display.
• When updating is complete the power indicator lights green and normal status is resumed.
(5) Press the MENU button to close the menu.
--- Cautions on Firmware Update ---
• In order to use these functions, you must have the correct system requirements and settings for a broadband Internet
connection.
• Do not turn off the power until updating is completed.
Even with a broadband connection to the Internet, approximately about 1 hour is required for the updating procedure to
be completed.
Once updating starts, normal operations on the AVR-3310 cannot be performed until updating is completed. Also, setting
items of the GUI menu of AVR-3310 or setting items of the image adjustment may be initialized.
Make a note of the settings before updating, and set them again after updating.
