tank� By pressing two buttons at once, the diagnostic
functions can be accessed�
Sender pads are installed and stuck to the sides of
the holding tank� The sender pad scans the water
level through the tank wall using digital techniques
programmed into the sender microprocessor�
To Read a Water or Sewer Tank Level
1� Press the button corresponding to the tank to be
checked and release it, the display will show the
levels in percent on the LED display� If no other
button is pressed, then the display shuts off after
about 5 seconds�
2� If another button is pressed before 5 seconds, the
display will immediately switch to show the new
level or voltage� The 5 second time-out is restarted
every time a button is pressed�
3� To continuously display a reading, press and
release the desired button, and then press the
same button a second time� When the button is
released, the display will be on hold mode, which
is indicated by the decimal point on the right hand
side turning on� While the display is in the hold
mode it will recheck the level once per second
so the user can watch the level change while the
tank is being filled or drained. The display will
automatically shut off after 5 minutes in hold mode�
To end the hold mode before the 5 minutes is up,
press any tank button, and the display will shut off�

To Read the Battery Voltage

1� Press the BATT button and release it, the display
will show the battery (House) voltage on the LED
display
2� If no other button is pressed, then the display will

Solar System

Airstream utilizes Go Power Flex-100 solar panels
and a Sun Explorer Controller/Display System� The
Sun Explorer display panel is located in the roof
locker above the TV� Ensuring the panels are clean,
not partially shaded by trees or other interference will
promote solar charging�
The Sunexplorer charge control performs these basic
functions:
1� It senses when the battery is fully charged and
disconnects the charge current to avoid over-
charging the battery�
2� It resumes charging the battery when the battery
voltage has dropped sufficiently to accept
additional charge current�
3� It checks the availability of charge current, by
cycling the relay every 4 minutes� If there is
insufficient charge current available, it's internal
relay will disconnect the battery to prevent
discharge through the solar panels at night�
Three different colored LED's indicate the status of the
battery charge� Green = Full, Yellow = Partial, blinking
Orange = low� When orange LED is blinking, due to low
voltage, both the green and yellow LEDs will be dimly
lit� Manuals on their use are included with the Airstream
owner's packet�
