INSTALLING THE BATTERY

Open the battery compartment (callout D of Fig. 1) by pulling its
cover away from the grip. Then plug the 9V battery that comes
with the IRT657 into the wired socket inside the compartment.
The terminals of the battery and the socket mate in only one way,
with the smaller male terminal plugging into the larger female
terminal. Close the battery compartment by snapping it shut.
