SPECIFICATIONS
USAGE
USAGE & SAFETY
The radon sensors in Corentium Pro are made for
inside use only. Avoid storing or using the monitor
in environments with high humidity, extreme heat, or
freezing conditions. Condensation can form on the
monitor if it is moved from a warm location to a cold
location or vice versa. If condensation forms on the
monitor, remove the batteries and leave it in a dry
environment for 2 hours. The monitor should not be
used in environments with more than 85% relative
humidity. The unit must not be exposed to direct sunlight
for extended periods. Avoid subjecting the monitor to
shocks, impacts, pressure, vibrations, dust, or moisture.
Only use alkaline AA (LR06) batteries. The batteries must
not be exposed to fire or other extreme heat. The battery
terminals must not be touched, and they must be kept
free from dust, sand, liquids and other foreign objects.
Use a Kensington cable Lock (often used for laptops)
