Battery life and temperature
The amount of time that the USM 100 can be run on fully
charged batteries (and the heat generated internally) is
directly related to current consumption in the instrument
electronics.
One of the largest consumers of current, and the one
most directly controllable by the user, is the brightness
of the display. Running the display brighter than neces-
sary will drain the battery faster and make the instru-
ment run hotter.
We recommend setting the display brightness as low as
possible (see page 109) and choosing the best color
scheme for your lighting conditions. Our experience
shows that 25% brightness works well for most applica-
tions, with the
DARK color scheme for indoor use and
the LIGHT color scheme for outdoor (see page 109).
Disposal of batteries
Lithium batteries are marked with the symbol of the
crossed-out trash can.
The symbol reminds you that batteries should not be
disposed of with household waste, but must be collect-
ed separately (see
Disposal of batteries , page 301).
To prevent short circuits and the associated heating lith-
ium batteries must never be stored or transported un-
protected (see
Transport and storage , page 259).
