2.2

Type of Batteries

4 x 1.5V AA batteries, standard, alkaline or rechargeable.

2.2.1

To Remove Batteries.

Remove the batteries from the holder by pulling on the ribbon or using

a thin screwdriver to ease them out.

2.2.4

Low Battery Indication

If the battery voltage falls below a pre-determined level, the display

will show battery symbols at both ends of the top line of the display.

The instrument will still operate correctly but only for a limited time so

the batteries should be replaced as soon as possible (Also use of the

backlight should be avoided to maximise remaining operating life of

the batteries).
