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 Micom.
Initializing AV SURROUND RECEIVER
AV SURROUND RECEIVER initialization should be performed when the Micom, peripheral parts of Micom, and Digital P.W.B. are replaced.
1. Turn off the power using ON/STANDBY button.
2. Press ON/STANDBY button while simultaneously pressing STANDARD and DSP SIMULATION buttons.
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.
Service Jigs
When you repair the printing board, you can use the following JIG (Extension cable kit).
Please order to Denon Official Service Distributor in your region if necessary.

VERSION UPGRADE PROCEDURE OF FIRMWARE
You can update by downloading the latest firmware from the Internet.
1. Connecting to the Network
(1) System Requirement
# Internet Connection by Broadband Circuit
# Modem
# Router
# Ethernet cable (CAT-5 or greater recommended)
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-3311 cannot be performed until updating is completed. Also, setting items of the GUI menu of AVR-3311 or setting items of the image adjustment may be initialized.
Make a note of the settings before updating, and set them again after updating
Idling Current
Required measurement equipment: DC Voltmeter
1. Preparation
(1) Avoid direct blow from an air conditioner or an electric fan, and adjust the unit at normal room temperature 15 °C ~ 30 °C (59 °F ~ 86 °F).
(2) Presetting
# POWER (Power source switch) STANDBY
# SPEAKER (Speaker terminal) No load
(Do not connect speaker, dummy resistor, etc.)
2. Adjustment
(1) Remove top cover and set VR401, VR402, VR403, VR404, VR405, VR406, VR407 on 7CH AMP UNIT at fully
counterclockwise position.
(2) Connect DC Voltmeter to test points (FRONT-Lch: TP401, FRONT-Rch: TP402, CENTER ch: TP403, SURROUNDLch: TP404, SURROUND-Rch: TP405, SURROUND-BACK Lch: TP406, SURROUND-BACK Rch: TP407.
(3) Connect power cord to AC Line, and turn power switch "ON".
(4) Presetting.
MASTER VOLUME : "---" counterclockwise (c min.)
SPEAKER (Speaker terminal) : No load
(Do not connect speaker, dummy resistor, etc.)
MODE : MCH STEREO
FUNCTION : DVD
(5) Within 2 minutes after the power on, turn VR401 clockwise to adjust the TEST POINT voltage to 8 mV ± 0.5 mV DC.
(6) After 10 minutes from the preset above, turn VR401 to set the voltage to 8 mV ± 0.5 mV DC.
(7) Adjust the Variable Resistors of other channels in the same way.
