Maximum Wireless Merlin, Mystic & Rainwatch (pre-2006) - Manual (Page 7)

VII. Battery Information
- The AA alkaline batteries in the Temperature and Rain Collector transmitters
should last from 1 – 2 years depending on changes in condition. We
recommend replacing the batteries annually to avoid loss of data.
- The AA NiCad batteries in the Wind transmitter will continually recharge via the
internal solar charging system. The characteristics of NiCad batteries are such
that they could need replacement every 2 -3 years. The life expectancy varies
depending on many factors, including temperature and amount of sunshine at
your location
.
VIII. Error displays
When no data is received at the “In” terminal of a Merlin or Mystic the display will show a series
of dashes.
If a transmitter is no longer responding to the receiver, Merlin and/or Mystic will display “NS” (No
Signal) followed by one or more bars indicating which transmitter is not responding. The top bar
is wind, the middle bar is temperature and the bottom bar is rain.
Examples:
Wind not responding
Temperature not responding
Wind and rain not responding
