Instruction Manual
UHF FM Transceiver
VHF FM Transceiver

Introduction
Thank you very much for purchasing this excellent Alinco transceiver. Our products are ranked among the
nest in the world. This radio has been manufactured with state of the art technology and it has been tested
carefully at our factory. It is designed to operate to your satisfaction for many years under normal use.
Please read this manual completely from the rst page to the last, to learn all the functions the
product offers. It is important to note that some of the operations may be explained in relation
to information in previous chapters. By reading just one part of the manual, you may risk not
understanding the complete explanation of the function.
Before transmitting
There are many radio stations operating in the frequency ranges this product covers. Be careful not to
cause interference when transmitting around such radio stations.
■ Lightning
Any person is not safe outdoor during thunderstorm and lightning. This condition is getting worse if
somebody keeps a hand-held radio; chances of being hit by lightning are doubled since lightning may
hit a radio antenna as well. At this time, there is no hand-held radio having any kind of protection against
lightning current (which is higher than10 kA.). 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 its hand-held radios outdoor or inside the car during lightning.
■ About IP54 rating / Dust and splash resistant
About IP54 rating

5: Dust protected /Ingress of dust is not entirely prevented, but it must not enter in sufcient quantity to
interfere with the satisfactory operation of the equipment; complete protection against contact.
4: Splashing water / Water splashing against the enclosure from any direction shall have no harmful effect.
Test duration: 5 minutes / Water volume: 10 litters per minute /Pressure: 80~100 kN/m²
The IP54 designation provides for limited dust and splash proong of the radio per specied above. This
compatibility is factory guaranteed for a period of one year provided all the jack covers are securely in
place, any accessories connected must be specied genuine Alinco accessories and the radio has not
been disassembled by the customer. The factory has tested and made the equipment compatible to IP54
certication during engineering. However, please understand that this equipment is NOT certied IP54
compliant but is designed to remain operational when used in hard conditions and is in no way stating
that you should attempt to wash the radio for cleaning. Warranty will not cover radios that are water/dust
damage due to negligence or misuse of the product.
The warranty period of dust and splash resistance is the same as the period of the product warranty.
■ Covering ranges
You may expect a range of approx.3km/2 miles or more at high-power when located on a at, noise-free
place like on a beach.However,it may vary drastically depending on how to wear and carry the radios,
surrounding locations/conditions and static noise levels (below or near power transmission lines), etc. In
urban areas with many buildings or inside a building, such covering range will become drastically short
even to several tens of meters.

■ Output power selectable 5W/2W/0.5W
■ 128 PC-programmable channels (16ch x 8groups)
■ Li-Ion battery pack and stand-charger as standard accessories
■ Voice Compander (Reduce Noise & enhance audio clarity)
■ Inversion Scramble(Analog encryption)
■ Sub-tone (CTCSS/DCS) Encode/Decode and DTMF
■ VOX built-in

SAFETY TRAINING INFORMATION
Warning: Please Read Carefully
•DO NOT operate the transceiver without a proper antenna attached, as it may damage the transceiver
and may also cause you to exceed FCC RF exposure limits. A proper antenna is the genuine antenna
supplied with this transceiver by Alinco or ones specically authorized by the antenna manufacturer for
use with this transceiver.
•ALWAYS keep the antenna at least 3 cm (1 inch) away from your body when transmitting and only use
the original belt clips when attaching the transceiver to your body (Unauthorized attachment devices may
help radiating more electromagnetic energy). To obtain the best sound quality during communications,
hold the antenna at least 6 cm (2 inches) from your mouth, and slightly off to one side.
•Use only the genuine Alinco accessories listed in this instruction manual for RF safety. Third party
accessories are not guaranteed for RF safety by Alinco.
• Electromagnetic Interference/Compatibility
During transmissions, a transceiver generates RF energy that can possibly cause interference with other
devices and/or systems.
To avoid such interference, turn off the transceiver in areas where signs are posted to do so. NEVER
operate transceivers in areas that are sensitive to electromagnetic radiation such as hospitals, blasting
sites, aboard aircraft and similar advanced vehicles etc. Do not expose magnetic cards such as credit
cards in a very close vicinity to a transceiver; it may erase the magnetic data. A person using medical
devices such as a pacemaker MUST NOT use this transceiver, as interference may cause malfunction to
such medical devices.

• Occupational/Controlled Use
This product is used in situations that users are exposed to RF as consequence of their employment
provided those users are fully aware of the potential RF hazards and can exercise control over their
exposure.
• This transceiver is NOT ATEX approved and NOT intended for the use in hazardous explosive
atmospheres.
