Battery Compartment
Two thumb screws on the battery compartment cover allow quick access to the
lithium-ion battery pack without the need for tools (see Figure 1-20 on page 40).
The battery compartment cover also has a small hole in the bottom center area that is
covered on the inside by an environmentally sealed membrane vent.
IMPORTANT
The membrane vent is a safety feature that is required in the event that the instrument
battery fails and emits gas. This vent must not be punctured.
