If the computer only has USB 3, try connecting a powered USB 2.0 hub directly to the computer and then plug the
Logger into the hub.
Q:
When the Logger is disconnected from the computer, the computer displays a warning “The disk was not ejected
properly” (OS X) or “Disk surprised removed/Problem ejecting USB mass storage device.” (Windows)
A:
Make sure to disconnect the unit properly using the “Disconnect” button from the Logger palette in
AcqKnowledge. If unavailable, make sure to eject the BNLOGGER disk in the Finder (OS X) or use the Safely
Remove Hardware notification area icon to eject the BNLOGGER disk (Windows).
Q:
The Logger does not appear to be charging.
A:
The Logger may be connected to a low-power USB port, requiring the battery to be used to power the Logger.
The Logger must be connected to a high-power USB port or the included AC adapter to charge. Connect the
Logger to the included AC wall charger. If a Logger has a fully dead battery, computer USB ports may not
provide enough power to allow the unit to fully power on, or it may freeze during power-on self-test. Batteries do
not charge during self test. If the Logger does not turn on:
1.
Plug the Logger into mains power using the included AC power adapter until the Main menu appears.
2.
Once the Main menu appears and the BioNomadix startup screen disappears, the Logger will begin
charging. Depending on how low the battery level has fallen the Logger may beep and attempt to restart
several times before reaching the Main menu.
3.
Leave the logger connected to mains power for at least four hours to recharge the battery.
Q:
The Logger does not power on after connecting to AC power for charging.
A:
This can happen if the Logger has not been used for a long period of time and the battery has become fully
depleted. In this case there may not be enough power for the Logger to self start. If this occurs:
1.
Plug the Logger into mains power using the included AC power adapter.
2.
Power on the Logger by pressing and holding the leftmost button until the main menu appears.
3.
Verify that the battery icon in upper right of the screen is blinking. This indicates the battery is charging.
Q:
Unable to navigate between menu items on the Logger menus.
A:
Multiple buttons may be being pressed at the same time. Make sure to press firmly directly on the white button
area towards the edge of the Logger case.
Q:
When importing all logs appear to have a date of “January 2000”.
A:
The clock on the Logger is not properly set. Set the proper date and time from the “Configure” menu.
Q:
My Logger is beeping continuously!
A:
The “low battery alarm” may be enabled. Disable the alarm from the “Configure” menu or plug the Logger into
an AC adapter to charge. If the Logger continues beeping, contact BIOPAC technical support.
Q:
After importing the signal drops to zero in portions of the data.
A:
The Logger was unable to communicate with the transmitter during these periods. Try using a different RF
channel and following the position optimization guidelines to improve RF performance.
Q:
I connected the Logger to a computer while data acquisition was in progress and now I can't import my logged
data.
A:
IMPORTANT:
Do NOT connect the Logger to a computer while a data acquisition is in progress. The
acquisition will be halted and data will be lost if the Logger is connected to a computer while a data acquisition is
in progress.
Q:
How do I reset the Logger?
A:
The Logger can be reset by pressing the recessed Reset button located opposite the USB port. Use an unbent
paper clip to activate the button.
