E-43Uniden MHS335BT Radio Owner’s Manual
Problem Things to Try
I can transmit, but no one
can hear me.
Check your UIC channel settings: does the area you are in use
dierent channel assignments?
I’m not getting hazard
alerts.
Make sure Weather Alert Watch is turned on.
The display ashes, and I
don’t know why.
The channel number on the display will ash if the radio is
in a Watch mode or in Scan mode. Try turning o scanning,
Weather Alert Watch, Triple Watch, or Dual Watch beginning
on Page E-20.
Scan won’t start. Be sure you have channels saved into Favorites.
No beeps sound. Key beep is set to OFF. Turn Key Beep on.
I cannot send DSC calls.
- Make sure the MMSI (DSC self ID) is entered.
- Turn ON the DSC Switch in the menus.
I cannot receive GPS
position data.
Reposition the radio so that nothing blocks the antenna from
the satellite signal.
Where can I nd my
radio’s serial number?
The serial number is on a plate inside the battery compartment.
When I turn on the radio,
I get a message that
"positioning data is not
acquired."
Be sure there are no obstructions between the radio's antenna
and the sky. If you are inside the cabin, move outside.
