Standalone Operation
Position the Monitor
1 Place the radon monitor in the desired position in the area to be monitored
for radon gas. The radon monitor does not need to be level.
2 To use a tripod, thread the standard tripod screw (1/4-20UNC) into the
threaded fitting on the bottom of the case (Figure 4).
Figure 4. Using a Tripod
Install a Fresh Battery
The radon monitor can be operated on battery power or AC power. When
connected to AC power, the battery provides back-up power. However, even
when operating on AC power, a battery must be installed to provide backup
power.
With the radon monitor disconnected from AC power, a fresh alkaline battery will
operate the device for about 100 hours, or a fresh lithium-ion battery for about
300 hours.
WARNING:
Always install a fresh 9V battery before test or storage,
even when the unit is connected to AC power, to prevent the internal
3V battery from discharging. The 3V battery will discharge in 15 min-
utes; the battery is not user-serviceable and if discharged, the unit
must be returned to Sun Nuclear for replacement.
