b. If the OBS-3A still fails to respond, try changing baud rate speeds by
selecting Attempt to find the baud rate to communicate. If this fails,
switch the PC back to 115.2 kB and go to the next step.
c. Reconnect the cable and try to connect again.
d. Replace the main batteries; see Section 6.1.2, Battery Installation, and
try to connect again.
e. If you have a survey cable, connect instrument to external power and
try to connect again.
f. Remove the unit from the pressure housing and press and release the
RESET button. Try to connect again.
