Discussing SCAMP Maintenance

REPLACING THE BATTERIES

Replace the batteries by following these steps:

  1. Do not attempt to replace batteries in a location where the SCAMP is subject to becoming wet while the pressure case is open.

  2. Remove the I/O cable connection if required.

  3. Open the SCAMP as described in the Opening the SCAMP section.

  4. Pull the cable loose from between the batteries and the chassis wall. Next, pull the 9v batteries out. Disconnect these.

  5. Open the velcro flaps and remove the AA batteries.

  6. Install fresh AA batteries and close the velcro straps. When installing insure that the polarity is proper.  There is a diagram located in the AA battery cavity that shows proper AA battery installation.

  7. Install fresh 9V batteries. BE CAREFUL NOT TO REVERSE THE POLARITY. IF YOU TOUCH A BATTERY TO THE CONNECTOR IN THE REVERSE DIRECTION, EVEN FOR AN INSTANT, THEN THE FUSE LOCATED IN THE 9V CONNECTOR WIRES WILL BE BLOWN. THIS WILL NOT DAMAGE THE SCAMP, BUT A NEW FUSE MUST BE INSTALLED.  See Replacing the Fuses if this happens.

  8. Replace the 9V batteries. Press the cable between the batteries and the chassis.

  9. Close the SCAMP as described in Closing the SCAMP section.

  10. Leak test as described in Testing for Leaks section.

  11. Replace the I/O cable if previously connected.
  12. SCAMP forgets its time and date when digital batteries are replaced. This must be re-initialized by connecting SCAMP to the host computer and running the SCAMP Control Dialog. Once the Dialog screen appears the time and date have been automatically initialized from the host computer’s time and date. No further action is necessary.
