Battery replacement
Low battery voltage is indicated on the display with blinking reading "BAT". It is necessary to
replace it with new one as soon as possible. Battery is located under small cover on the instrument
lower side. It is absolutely necessary to replace battery with instrument switched OFF, otherwise
setting of d.REF. and AUDI (from menu selections) and data in memory HOLD, MIN and MAX
will be lost. For the same reason do not disconnect the battery for longer than 1 minute even if
instrument is switched OFF. If it happens (or if battery is totally discharged), it is necessary to set
again in appropriate menu selection LCD refreshment mode (d.REF.), alarm audio indication
(AUDI) and clear the minimum and maximum memory (CLR).
