Uniden UM425 VHF DSC 사용자 설명서

The UM425 can sit at any angle in the mounting bracket so it can easily 

accommodate the best location. First, determine the best place to mount the 

radio. For optimum performance, find a location that can:

• 

Properly support the weight of the radio, approximately 2 pounds or 

0.9 kilograms. You may need to use some type of anchor with the 

mounting screws to hold the radio, depending on the surface.

• 

Keep the battery leads as short as possible. 

• 

Keep the antenna lead-in wire as short as possible. 

• 

Allow free air flow around the heat sink on the rear of the radio.

• 

Avoid interference with the ship’s compass.

Install the radio into the mounting bracket, and connect the 

1. 

cable and accessory cable.

Step 1: 
Slide the radio 
into the mounting 
bracket.

Step 2: 
Tighten the mounting knobs 
to secure the radio in place.
