6.2 Resetting the System
Three types of reset are available for the Chartplotter:
• Power-On Reset: When you turn the display unit off, then on again,
the screen reverts to the chart display with all windows cleared.
• Hardware Reset: This procedure enacts a power-on reset if the unit
has entered a lock-up condition.
To perform a hardware reset, press and hold the POWER key for 9
seconds.

Hope this helps.
Good Luck!

These are tenths of a meter. It is written that way to be clearer. Suppose the depth is 10.5 metres. If it were written as 10.5 the decimal point might not be clear and could lead to confusion so they put the decimal lower and to the right.

If none of these solutions work, you may need to contact Raymarine customer support for further assistance or repair. Take care and have a great day! -Alex

After nearly 4 years I dunno if you got this sorted. The question is ambiguous, as Raymarine radar comes with wiring harnesses; the display end is a plug-and-play 12-pin male to the harness end female; the other end goes up the mast in a plastic sleeve to prevent damage to the 8-pin connector and the 2 or 4 power cables (depends on "light" or "heavy"). There's a means of connecting a digital radar to the C120 but I don't have that so don't know the specifics. Is this the sort of information you were looking for?
