Follow all relevant national regulations applicable in the country of use. Be Aware of the Warranty Regulations The warranties made by MSA The Safety Company with respect to the product are voided if the product is not used and maintained in accordance with the instructions in this manual. Please protect yourself and others by following them.
Safety Regulations Warranty ITEM WARRANTY PERIOD Chassis and electronics Four years All sensors unless otherwise specified Four years XCell EX-H Sensor One year Specific battery run-time over temperature is not warranted. This warranty does not cover filters, fuses, etc. As the battery pack ages, there will be a reduction in usable device run time.
The alarm levels for the individual gases are factory-set and can be changed through the Setup Menu. These changes can also be made through the GALAXY GX2 Test Stand or MSA Link software. Ensure that the latest version of the GALAXY GX2 firmware or MSA Link software has been downloaded from MSA’s website www.msasafety.com.
When the device fails a bump test or when the 24-hour period expires, the red (Bump LED) LED flashes every 15 seconds. This option can be turned off through the MSA GALAXY GX2 Test Stand or MSA Link software. The red alarm LEDs are visual indications of an alarm condition or any type of (Alarm LED) error in the device.
Description Backlight The backlight automatically activates when any front panel button is pressed. The backlight remains on for the duration of the user-selected timeout. This duration can be set through MSA GALAXY GX2 Test Stand or MSA Link software. Horn The horn provides an audible alarm.

Bump test frequency is often stipulated by national or corporate regulations; however, bump testing before each day’s use is generally the accepted best safety practice and is therefore MSA’s recommendation. This test quickly confirms that the gas sensors are functioning. Perform a full calibration periodically to ensure accuracy and immediately if the device fails the Bump Test.
30 minutes before performing a Calibration. NOTE: The GALAXY GX2 Test Stand is not a CSA certified calibration method. Under normal circumstances MSA recommends calibration at least every six months, however, many European countries have their own guidelines. Please check your national legislation.
