9 OPERATION AND MAINTENANCE OF INSTRUMENT
9.1 CAUTION AND HINTS
Always remember the following points in order to get the best from your instrument:
− The instrument is designed to operate under mains power. It should be used on the power of the internal
rechargeable Ni-Cd battery only for short intervals.
− The battery recharges automatically when the instrument is connected to the mains.
− The I/O switch does not disconnet the instrument from the mains, but merely switches off the instrument's low
voltage circuits.
− The backlight should be switched off when the instrument is running off the battery. The backlight can be turned on
temporarily by means of a button on the rear panel.
− Regularly check for the amount of paper left and for printer cartridge wear. Do not allow the printer to operate
without paper as this causes rapid wear.
− If the printer does not work, an internal fuse may have blown. Refer the instrument to an authorised assistance
centre.
