Uniden UM425 VHF DSC 사용자 설명서

The Australian Maritime Safety Authority allocates MMSI. To apply for an 

MMSI complete the MMSI  Application form available for download via  

www.amsa.gov.au/mmsi. This page has important information about MMSI 

and DSC radio.

The minimum qualification to operate a VHF radio with or without DSC is a 

Marine Radio Operator’s VHF Certificate of Proficiency (MROVCP). VHF 

radios are covered by a Class License so an individual station license is no 

longer required.

The Marine Radio Operator’s Handbook produced by the Australian Maritime 

College provides further information about qualifications, licensing and DSC 

operations. It is available at 

Your UM425 has been designed to accommodate all of the popular marine VHF 

antennas. However, the selection and the proper installation of the antenna is the 

responsibility of the user or installer.
The antenna used with this radio should be installed using the following guidelines to 

ensure a safe distance between the antenna and persons close by.

Small whip antennas (3 dB) or smaller should be installed with at least 1m away 

• 

from any area where people are likely to be.
Larger antennas (6 dB or 9 dB) should be installed with at least 2m away.

• 

While the radio is transmitting, do not come closer to the antenna than the 

• 

recommended safe distance.
Do not touch the antenna when the radio is powered on and might begin 

• 

transmitting.
