Do not use any chemicals to clean the data loggers. Clean the Optics with warm water and mild dish detergent. If the build-up is not removable with dish detergent, you may use toothpaste and a soft cloth as a mild abrasive cleaning agent.<\/span><\/span><\/p>\r\n\r\n<p><span style=\"font-size:11px;\"><span style=\"font-family:arial,helvetica,sans-serif;\">If the communications window is scratched and you cannot offload data, apply mineral oil to the surface and try again. <\/span><\/span><\/p>\r\n\r\n<p><span style=\"font-size:11px;\"><span style=\"font-family:arial,helvetica,sans-serif;\">Check your installed HOBOware version to insure support for the product you are using. <\/span><\/span><\/p>\r\n\r\n<p><span style=\"font-size:11px;\"><span style=\"font-family:arial,helvetica,sans-serif;\">If launching or offloading in direct sunlight, try shading the logger if you are having trouble.<\/span><\/span><\/p>\r\n\r\n<p><span style=\"font-size:11px;\"><span style=\"font-family:arial,helvetica,sans-serif;\"><strong>U24 and U26 Users:<\/strong> <\/span><\/span><\/p>\r\n\r\n<p><span style=\"font-size:11px;\"><span style=\"font-family:arial,helvetica,sans-serif;\">Some loggers have a slight positioning preference caused by a slight internal misalignment of the optical LEDs, which may prevent them from communicating reliably. This is not a defect. Try turning the logger a few degrees in either direction while it is in the coupler. A related symptom of this is a false low-battery message. <\/span><\/span><\/p>","applications":["Water Resource Management"],"associated_products":["BASE-U-1","BASE-U-4","U-DT-1","U-DTW-1","U20-001-01","U20-001-02","U20-001-03","U20-001-04","U22-001","U23-001","U23-002","U23-003","U23-004","U24-001","U24-002-C","U26-001","UA-001-08","UA-001-64","UA-002-08","UA-002-64","UA-003-64","UA-004-64","UTBI-001"],"brand":"HOBO","documentation_hoboconnect":"0","documentation_intemp_app":"0","documentation_is_datasheet":"0","meta_tags":"a:1:{s:6:\"robots\";s:7:\"noindex\";}","resource_topic":["Troubleshooting & Maintenance"],"resource_type":"Tech Note","tech_note_type":["Communications"]}
