The VOXI EC User's Guide must be carefully read by all
individuals who have or will have the responsibility of using,
maintaining or servicing this product. The product will
perform as designed only if it is used, maintained and
serviced in accordance with the manufacturer's instructions.
• Never operate the monitor when the cover is removed.
• Remove the monitor cover only in an area known to be non-
hazardous.
• Use only mPower's sensor and accessories. Substitution of
components will impair intrinsic safety and void warranty.
• For optimal results, it is recommended to allow the unit to
warm up for 2 minutes after entering the test interface.
• For maximum safety, the accuracy of the instrument should be
checked by exposing it to a known concentration calibration gas
at regular intervals.
• Ensure that the gas inlet is not blocked.
• Ensure that all filters are clean and replaced on a regular basis.
• Remove the sensor only if necessary for repair. Zero and span
calibration are required once the sensor is moved.
Mount the VOXI EC to a wall or pole using the bracket and
pole loops provided.
