Grainger has contacted the product supplier and has been advised by them of the following:
Lithium battery, once activated has a two year operating life, no charging or calibration required for the device. Daily "bump test" to test the sensor is still recommended.
Scott Safety (SCOTT) warrants the Protege ZM PORTABLE GAS DETECTION
MONITOR PRODUCTS (THE PRODUCTS) to be free from defects in workmanship
and materials under normal use and service for a period of two (2) years beginning
upon the date of activation for all Protégé ZM Oxygen Monitors and All Other
Protégé ZM Monitors for three (3) years from date of activation or 24 months of
operational life, whichever occurs first. This warranty is valid only if the detector is
activated within one year from the original date of manufacture by SCOTT.
Thank you for using Grainger Ask and Answer.
