Setting up your DR-Ready modem
CONFIRMING THE CONNECTION
1. Turn on the power of the product (refrigerator, washer, dryer or
dishwasher) where the modem has been installed.
2. Connect the direct LAN cable to the modem’s Host I/F port. The
Power LED of the modem is lit.
3. The Pairing LED of the modem blinks at 0.5 second intervals for
up to 10 seconds while attempting to connect to the DRC.
If the auto connection process has failed, set the DRC to
allow connections and press the modem Pairing button to
connect them manually. When it attempts to connect, the
Pairing LED starts blinking at a 0.5 second interval and then
blinks at a 1 second interval for up to 25 seconds. (For the
procedures to set the DRC to allow connections, refer to the
DRC user manual.)
4. When the connection is established, the Pairing LED is lit.
While the DRC is transmitting the DR level, any one of
the Level 1, 2, 3 and 4 LEDs can be turned on after the
connection.
5. If you cannot make a connection, contact the service center.
CONNECTING MULTIPLE MODEMS
The ability of the DR-Ready modem to communicate may be impaired
depending on the operating environment (distance, obstacles,
interference, etc.). If the communication quality is insucient, you can
solve the problem by connecting more than one DR-Ready modem or
connecting a specialized modem.

• Up to 10 modems can be
connected to the DRC.
• A maximum 3 tree depth is
supported.
• Up to 10 modems can be
connected to the DRC.
(Including all the modems
used to construct the tree
topology.)
Connecting DR-Ready modems
The following is the way to communicate with the DRC via a modem
that is installed in another product (refrigerator, washer, dryer or
dishwasher).
DRC Modem-A Modem-B
• Modem-A: An existing DR-Ready modem that is installed in
another product.
• Modem-B: The DR-Ready modem that is installed in the product
you want to use.
1. Enter the MAC and PIN numbers of Modem-B into the DRC.
2. Connect Modem-B to the product you want to use.
3. Press the Pairing button of Modem-A. The Pairing LED blinks at
1 second intervals.
4. Press the Pairing button of Modem-B. The Pairing LED blinks
at 0.5 second intervals and Modem-B attempts to connect with
Modem-A.
5. When Modem-B is connected with Modem-A, the Pairing LED of
Modem-B is lit.
6. When the DRC is transmitting the DR level, the same DR level as
that of Modem-A is displayed on Modem-B.
Using a specialized modem
The following is the way to communicate with the DRC via a
specialized modem.
DRC Modem-A Modem-B
Specialized
modem
You have to purchase the specialized modem additionally.
1. Enter the MAC and PIN numbers of the DR-Ready modem into the
DRC.
2. Connect the DR-Ready modem to the product you want to use.
3. Supply power to the specialized modem using the Samsung
adapter (ATADU43KBK).
4. Press the Pairing button of the specialized modem. The Pairing
LED blinks at 1 second intervals.
5. Press the Pairing button of the DR-Ready modem. The Pairing
LED blinks at 0.5 second intervals and the DR-Ready modem
attempts to connect with the specialized modem.
6. If the DR-Ready modem is connected to the specialized modem,
the Pairing LED of the DR-Ready modem is lit.

TROUBLESHOOTING
Problem Solution
The modem is
not turned on.
• Check if the product is connected to the
power source.
• Check if the DR-Ready modem is properly
connected to the product with the direct
LAN cable.
• In the case of a specialized modem, check
if the adapter is connected.
The Pairing LED
is turned o or
all the Level 1, 2,
3 and 4 LEDs are
turned on.
• Check if the DRC in your house is working
properly.
• Check that the DRC is turned on.
• Check if the modem’s MAC and PIN
numbers have been entered into the DRC
correctly.
• Set the DRC to allow connections and
press the modem’s Pairing button
to connect them manually. (For the
procedures to set the DRC to allow
connections, refer to the DRC user manual.)
Both Level 1
and 2 LEDs are
turned on.
• Check if the DRC in your house is working
properly.
• Check that the DRC is turned on.
• Check if the modem’s MAC and PIN
numbers have been entered into the DRC
correctly.
• Set the DRC to allow connections and
press the modem’s Pairing button
to connect them manually. (For the
