Diffusion Monitor Battery Replacement or Changeover
The diffusion monitor can be used with all three Ventis MX4 battery packs.
The Li-ion battery kit is a single part consisting of the monitor’s lower case bottom and the battery. It is
removed from and attached to the diffusion monitor as a single item.
The Extended Range Li-ion battery pack and its cover are two distinct items.
The Alkaline battery pack consists of three items: the batteries, the battery pack, and a battery pack cover
(the same cover that holds the Extended Range Li-ion battery).
NOTE: When an Extended Range Li-ion (or Alkaline) battery pack is attached to a diffusion monitor, the monitor’s lower portion becomes
deeper than its upper portion. The Conversion Kit’s suspender clip components are used to make the upper and lower portions depth-
compatible. The Conversion Kit provides a battery cover (battery not included), a suspender clip and spacer, and a screw and washer.
