Page 277 7 years after manufacture of this model is terminated. If damage is suspected, check the "Troubleshooting" section before contacting your dealer or Hioki representative. When sending the instrument for repair, pack the instrument carefully so that it will not be damaged during shipment, and include a detailed written description of the problem.
Page 278 ______________________________________________________________________________________________ Printer Head Cleaning (when the 8994 PRINTER UNIT is installed) In normal use, the printer does not require periodic maintenance. However, depending on usage conditions, the thermal head may become contaminated by dust or paper scraps. If the print seems light or if there are dropped sections, clean the head as described below.
Page 279 ______________________________________________________________________________________________ 14.2 Replacing the Input Modules To avoid electric shock accident, before removing or WARNING replacing an input module, confirm that the instrument is turned off and that the connection cords are disconnected. The mounting screws must be firmly tightened or the input module may not perform to specifications, or may even fail.
Page 280 ______________________________________________________________________________________________ 14.3 Removing the Battery Before Discarding the Unit To avoid the risk of electric shock, be sure that all cables, the WARNING power cord and thermocouples are disconnected before removing the battery. Dispose of the battery as prescribed in your community. The 8855 incorporates a lithium battery for memory backup.
