MONITOR CONVERSION
To convert a diffusion monitor to an aspirated monitor, only the Extended Range Li-ion or Alkaline battery packs are
approved for use.
To convert an aspirated monitor to a diffusion monitor, a suspender clip, washer, and screw are recommended for
use with the Li-ion battery pack. If attaching the Extended Range Li-ion or Alkaline battery packs, the conversion kit is
required.
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.
