Before transmitting
There are many radio stations operating in proximity to the frequency
ranges this product covers. Be careful not to cause interference when
transmitting around such radio stations.
■ Covering ranges
It may vary drastically depending on the type and location of antenna
system. Please consult your dealer for details as DR-CS25 requires an
external antenna.
■ Lightning
Any person is not safe outdoors during thunderstorms and lightning. Note
also that no car provides adequate protection of its passengers or drivers
against lightning as well. Therefore, Alinco will not take responsibility
for any danger associated with using radios outdoors or inside the car
during lightning.
■ Electromagnetic Interference/Compatibility
During transmissions, your radio generates RF energy that can
possibly cause interference with other devices or systems. To avoid

FCC WARNING
This equipment generates or uses radio frequency energy.
Changes or modifications to this equipment may cause harmful
interference unless the modifications are expressly approved in the
instruction manual. The user could lose the authority to operate this
equipment if an unauthorized change or modication is made.
INFORMATION TO THE DIGITAL DEVICE USER REQUIRED BY THE FCC
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation.
This equipment generates, uses and can generate radio frequency
energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However,
there is no guarantee that the interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the interference by
one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment to an outlet on a circuit different from that to
which the receiver is connected.
• Consult the dealer for technical assistance.

The transceiver may be installed in any position in your car, where the
controls and microphone are easily accessible and it does not interfere
with the safe operation of the vehicle. If your vehicle is equipped with
air bags, be certain your radio will not interfere with their deployment. If
you are uncertain about where to mount the unit, contact your vehicle's
dealer.
Put the pads to both sides
for more tightened.
Caution:
Use only the provided screws
otherwise you risk damaging the
circuit board, components or fall-off
of the unit.
RF Hazard Warming
The electro-magnetic (radio Frequency) exposure level of this
device may exceed the European standards of the hazard level
when transmitting at the high-power setting while connected to a
unity gain antenna at a distance of 63cm or less from the operator.
Furthermore, the hazardous RF exposure level depends on the
conditions of the combination of the antenna gain, distance from
the operator, output setting and installation environment, therefore
the operator may be exposed to stronger RF even at a distance of
more than 63cm. For safety purpose, it is recommended that the
antenna be installed outside of, and as far as possible from, the
operator’s area. Avoid using an excessively high-gained antenna
in case the distance between the operator and the antenna is
very limited. Always use the minimum necessary output power for
communications.
CAUTION:

Initial Installation
DC Power Cable Connection
Mobile Operation
The vehicle battery must have a nominal rating of 12V. Never
connect the transceiver to a 24V battery. Be sure to use a 12V
vehicle battery that has sufficient current capacity. If the current
to the transceiver is insufficient, the display may darken during
transmission, or transmitting output power may drop excessively.
1. Route the DC power cable supplied with the transceiver directly
to the vehicle's battery terminals using the shortest path from the
transceiver.
Never use the cigarette lighter socket as a DC source.
The entire length of the cable must be dressed so it is isolated from
heat, moisture, and the engine secondary(high voltage) ignition
system/cables.
2. After installing cable, in order to avoid the risk of damp, please
use heat-resistant tap to tie together with fuse box. Don't forget to
reinforce whole cable.
3. In order to avoid the risk of short circuit, please cut down
connection with negative (-) of battery, then connect with radio.
4. Confirm the correct polarity of the connections, then attach the
power cable to the battery terminals; red connects to the positive (+)
terminal and black connects to the negative (-) terminal.
Never remove the fuse holders from the cable.
5. Reconnect any wiring removed from the negative terminal.
6. Connect the DC power cable to the transceiver's power supply
connector.
Press the connectors rmly together until the locking tab clicks.

2Initial Installation
Be sure to turn off both the transceiver and power supply before start
setting and connections.
In order to use this transceiver for xed station operation, you will need
a separate 13.8V DC power supply (not included) , Please contact local
dealer to require.
The current capacity of your power supply must be 12A or more.
1. Connect the DC power cable to the regulated DC power supply
and ensure that the polarities are correct. (Red: positive, Black:
negative).
Never directly connect the transceiver to an AC outlet.
Use the supplied DC power cable to connect the transceiver to a
regulated power supply.
Do not substitute a cable with smaller gauge wires.
2. Connect the transceiver's DC power connector to the connector on
the DC power cable.
Press the connectors rmly together until the locking tab clicks.

REPLACING FUSES
If the fuse blows, determine the cause, then correct the problem. After the
problem is resolved, replace the fuse. If newly installed fuses continue to
blow, disconnect the power cable and contact your dealer for assistance.
Only use fuses of the specied type and rating, otherwise the transceiver
could be damaged.

If you use the transceiver for a long period when the vehicle battery is
not fully charged, or when the engine is OFF, the battery may become

Initial Installation
External Speaker
If you plan to use an external speaker, choose a speaker with an
impedance of 8Ω. The external speaker jack accepts a Φ3.5mm (1/8")
mono (2-conductor) plug.
After being connected to an appropreate power source, press
PWR
key
to turn on. Press and hold
P3
key for 2 seconds to display the supplied
voltage.
The display immediately changes as the voltage supply changes, It also
displays voltage during transmission.
The transceiver will return to its normal operation when the power is
turned ON/OFF or repeat above operation.
Before operating, install an efcient, well-tuned antenna. The success of
your communication will depend on the type of antenna and its correct
installation.
Use a 50Ω impedance antenna and low-loss coaxial feed-line that
has a characteristic impedance of 50Ω, to match the transceiver input
impedance. Coupling the antenna to the transceiver via feed-lines having
an impedance other than 50Ω reduces the efficiency of the antenna
system and can cause interference to nearby televisions, radio receivers
and other electronic equipment.
The range of displayed voltage is from 9V to16V DC. Because the
displayed value is estimated, please use a voltmeter when a more
precise reading is desired.

Antenna Connection
Accessories Connections
Important
Transmitting without rst connecting an antenna or other unmatched
load may damage the transceiver. Always connect the antenna to the
transceiver before transmitting.
All xed stations should be equipped with a lightning arrester to reduce
the risk of re, electric shock, and transceiver damage.
