The Lowrance LVR-850 VHF

Marine Radio.

We're going to kick off the operation section with a brief description of the radio's basic functions. That will be followed by some important in- formation on Digital Selective Calling and basic instructions on how to make and receive calls.

Using the Keypad

The keypad has eight keys: H/L (Hi/Lo), WX (Weather), 16/9 (Priority Channels), SCN (Scan), MEM (Memory), CALL (Call) and ↑ ↓, the up-and- down arrow keys. When you press any of the keys a tone will sound. If you push a key and a 3-beep tone sounds, there is an error or the func- tion is not supported by the radio. You’ll notice several functions re- quire you to hold down a key for a few seconds. In those cases, a single beep sounds, then, after a few moments, a second beep will be heard to let you know you have successfully changed the mode.
