Battery replacement
Power is supplied by a 9 volt „transistor“ battery (NEDA 1604, IEC 6F22). The battery-symbol appears on the LCD
display when replacmenet is needed. To replace the battery, remove the three screws from the back of the thermo-
meter and lift off the front case. Remove the battery from case bottom.
Warning:To avoid possible electrical shock, disconect the thermocouple connectors from the thermometer before
removing the cover.
Attention
