Low Battery Messages
A 9V battery must always be installed, even when using an AC power supply, to
prevent discharge of the internal 3V battery. When the battery is low or needs to
be replaced, a message is displayed on the radon monitor. The following sections
describe the messages that may be displayed.
Low Battery with AC Power Connected
If the battery is low and the AC power adapter is connected, a message appears
when key 5 is pressed.
Replace the 9V battery as soon as the test is complete. See Replacing the 9V
Battery on page 6.
