Only LR20 alkaline cells will give the specified instrument
performance.

HAS INSTRUMENT BEEN USED AT LOW
TEMPERATURE?
The instrument performance of 15 hours is given at ambient
temperature between 15 Deg.C and 20 Deg.C; at lower
temperatures, particularly below freezing, battery capacity
can be dramatically reduced. Where the instrument is being
used at low temperature, replacement batteries should be
stored in warmer conditions where possible
