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

■
Safety
It is important that the operator is aware of, and understands, hazards
common to the operation of any transceiver.
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-MD520 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.
■
Enclosure protection
This transceiver is NOT water and dust protected. Avoid contacts with
water and dust, and if wet or dirty, immediately wipe them out with clean
dry cloth. This product is NOT anti-explosive.

When using the GPS receiver
• A GPS receiver is installed under the top panel. When the GPS receiver
is activated, do not cover the top part with anything that will block satellite
signals.
• GPS signals can't pass through metal objects. When driving or
navigating, you may risk not receiving GPS signals if covered by metal
roof. External antenna can't be connected, so we recommend to operate
near a window or on a deck.
• GPS signals can't reach to the receiver in places like:
- Tunnels or a shadow of tall buildings.
- Underground oors and parking lots
- Under a wide bridge
- In remote forested areas
Also in severe weather conditions, clouds, rain, snow etc may
obstacles signals also.
• The Global Positioning System is operated by the U.S. Department of
Defense. The Department is responsible for accuracy and maintenance
of the system. Any changes by the Department may affect the accuracy
and function of the GPS system.
