for each gas you wish to detect at the
correct alarm threshold for your region.
(Some cartridges may look different than
others, but will work the same.)

The cartridge will appear on the screen in
the box that correlates to the slot it was
placed in. The corresponding light above
the screen will glow red or green to indicate

The unit can be on or off when inserting a
cartridge. Make sure the contacts are clean
before inserting a new cartridge. Rub the
contacts in the monitor with your finger or a
pencil eraser to make sure they are clean.
Insert the cartridge into any of the 4 slots
in the monitor. First locate the top end so
the tabs line up, then push the bottom until
it clicks.
