No power to unit. Check 12 volt supply and polarity is
correct. Check fuse.
Reboot receiver by pressing all three keys simultaneously.

down (if screen is completely black) until display is visible.
RECEIVER IS IN STANDBY BUT RECEIVES NO
MESSAGES
No messages have been transmitted since the unit was
turned on. If local service is selected then check there is a
local service available.
The unit is incorrectly programmed. ie - it is not in range of
the stations it is programmed to receive. Try programming
for all stations and all messages and leave on overnight to
see what stations are available.
If there is still no reception check the antenna cable for
damage, inspect any joints and remake if defective.
Turn off any piece of equipment that may cause interference.
Shore power supplies can sometimes conduct interference
onto the boat so disconnect boat from shore power. Turn
off charger, particularly if it is of the inverter type.
