In very hot or cold conditions (outside the recommended
operating range of 0°C/32°F to 50°C/122°F), the LCD screen
may become inoperable, regardless of the contrast setting.
System reset
It may be necessary to reset the shuttle because of a crash or
unexpected communications failure. Resetting the shuttle does
not reset the clock or cause data to be lost. To reset the U-
Shuttle, turn the shuttle on, then briefly press all three buttons
simultaneously. Do not reset the shuttle while it is
communicating with (or attached to) a logger, sensor, or the
host computer.
Troubleshooting
If you encounter an error, refer to the list below for an
explanation.
Bad HOBO Battery
The shuttle cannot communicate with the U-Series logger,
because the logger’s battery is dead.
Comm Failure
or
Contact Lost
Button to Reset
The PC or logger was disconnected from the shuttle (or the
logger slipped out of its base station/coupler) while the shuttle
was communicating with it. To recover from this error, the
shuttle may need to reset itself. Press any button.
HOBO Is Stopped
The U-Series logger was disconnected from the shuttle before it
could be relaunched. If you intended to remove the logger
without relaunching, no further action is necessary.
Low Shut Battery
The shuttle’s main (AA alkaline) batteries are running low. The
shuttle will still function, but you should replace these batteries
soon.
Low Shut Clk Bat
The shuttle’s clock backup battery (CR1225) is running low. The
shuttle will still function as long as the main batteries have
power, but if the clock backup battery runs down further, the
shuttle’s clock may stop the next time you change the main
batteries.
Main Bat Too Low
The shuttle’s main (AA alkaline) batteries are too weak to
communicate reliably. You must replace the batteries before
you can continue working with the shuttle.
No Shuttle Info
The connected U-Series logger is compatible with the shuttle,
but cannot communicate with the shuttle until it has been
launched with HOBOware 2.2 or greater.
Not Enough Room
The shuttle’s memory is too full to accommodate the data from
this logger. Use HOBOware to offload the shuttle, then
relaunch the shuttle to delete the datafiles.
Optic Base Found
The shuttle detects a base station, but not a logger. The logger
or coupler may not be aligned or seated properly, or the logger
may have failed.
Shuttle Requires PC/Host Relaunch
The shuttle’s clock stopped because both the main batteries
and the clock backup battery were too low to keep it running.
The shuttle cannot be used again in the field until you relaunch
it. Ensure that the bad batteries have been replaced, then use
HOBOware to offload the data and relaunch the shuttle.
Unsupported HOBO
The connected device is an Onset logger, but the model is not
supported by the U-Shuttle. If this is a new logger model, the U-
Shuttle may simply need a firmware update.
Bad HOBO Err XXX
The shuttle cannot process the logger’s data. Try to read out
the logger directly with HOBOware, then relaunch the logger. If
HOBOware cannot read out the logger, refer to the
HOBOware
User’s Guide
for information about corrupted logger headers. If
the error persists after you have relaunched the logger, make a
note of the error number and contact Onset for support.
System Error XXX
If you receive a System Error, turn off the shuttle and
disconnect any devices. Then reconnect a device, check all
connections, and power the shuttle on again. If the error
persists, make a note of the error number and contact Onset
for support.
