Before Operating the Receiver
PS0633 DX-R8T/E
Attention
•Do not remove the case or touch the interior components.
Tampering can cause equipment trouble.
Do not use or keep the receiver where it is exposed to direct sunlight, dusty places, or near•
sources of heat.
Keep the receiver away from TV’s or other equipment when it•
interferes with reception.
Turn the power off immediately if the receiver emits smoke or•
strange odors. Ensure the receiver is safe, then bring it to the
nearest Alinco service center.
Notice to California resident users
The product that comes with this manual is free from dangerous material such as lead and
cadmium as per RoHS order of EU.
The receiver has no protection against lightning.
The user is responsible for providing adequate protection if he uses the device at home and
installs the antenna outdoor. Be aware that any outdoor antenna creates a direct path for lighting
current (more than 10kA) to the receiver. This path exists whether the device is turned ON or
OFF.
Any vehicle does not present a safe environment during lightning. This environment becomes
much more dangerous if an outdoor antenna is installed on the car. Move the antenna and its
cable into the car at the first sight of forthcoming thunderstorm and lightning.
Limited Power Source
Please note that the receiver enclosure only provides mechanical protection for its internal
parts; it will not contain a fire within the device if the fire starts under certain fault conditions.
Alinco will not take responsibility for any fire hazard associated with powering the receiver
or charging its batteries using a power source that does not belong to the limited power source in
the meaning of EN60950-1.

1-3 Installation and Connection Basics
Connection Diagram
Procedure
1. Connecting an antenna and ground cable
• Antenna connection
Use a properly-adjusted (low SWR) antenna to obtain optimum performance from the receiver. A 50 ohm
impedance coaxial with PL-259 connector is required for this connection.
NOTE: It is recommended to use commercially available antenna tuner for proper
antenna matching in case non-resonant antenna is connected.
• Ground connection
To prevent electric shock hazard and audio interference with other electronic appliances, bury a copper
rod or plate under the ground and connect it to the transceiver GND terminal. Use a heavy gauge, short
cable for this connection.
IMPORTANT: Do not ground the equipment on gas pipes, electrical conduits, or plastic water
pipes.

3. Connecting headphones
Connect a 3.5 mm diameter mono or stereo plug to the PHONES jack on the front panel.
NOTE: When headphones are used, no sound is heard from the speaker.
4. Connecting a regulated DC power supply
The Receiver requires a 12-13.8VDC negative grounded power source. Use a regulated power supply capable
of providing continuous current of 3A or more. Power supplies that do not meet those specications may
cause malfunction and/or damage to the radio and will void the warranty.
IMPORTANT: Before connecting, be sure to turn off the receiver and DC power supply.
* When a receiver is powered from an external DC power source, make sure
that this power supply has approval to the level of IEC/EN 60950-1.
Connect red to "+", and black to "-".
2. Connecting an external speaker (if not using the internal speaker)
Connect a 3.5 mm diameter mono plug to the SPEAKER jack on the front panel. Use a 3 W or higher external
speaker with 8 ohm impedance.
NOTE: When an external speaker is used, no sound is heard from the internal speaker.
When connecting an external speaker to the speaker jack on the front, use a 3.5 mm diameter stereo
mini plug, connect the top of the plug so that the speaker and base are grounded as shown in the
diagram below, and do not use the center pin. If a mono plug is used to connect, the clone jack on
the rear panel will no longer be usable, and the ERW-7 and ERW-4C will no longer be able to be used.

1. Remove 2 screws above the main unit to
separate the front-control panel.
Disconnect the cable.
2. Remove other 2 screws at the bottom of
the main unit.
3. Passing the separate-cable (5m) through
the hole of the cover in advance, connect
the cable to the main unit.
4. Fix the cover to the main unit using those
4 screws.
5. Fix the bracket using provided hardware,
and connect another end of the cable to
the front-control panel.
NOTE: Please be sure to keep the short,
original cable in order to make it back to
the original condition in future.
Provided ferrite-beads on the separate
cable are to eliminate the RF feed back.
The position of beads may affect to the
condition of RF feed back. See page 89
for troubleshooting.
5. Installing the control panel and body separately (optional)
IMPORTANT: Be sure to disconnect the power cable before carrying out this procedure.
