Warnings Warning: The Wind Guard MUST be removed when the bump test or calibration is complete. Failure to remove the Wind Guard will slow down EXO's response to hazardous gases. Warning: Only remove EXO's battery in a known safe environment with a clean atmosphere that is free of explosive gas. Warning: The EXO quick charger is NOT intrinsically safe. It should only be used in a safe environment with a clean atmosphere. Warning: DO NOT allow metal tools or personal items to touch the battery terminals. Touching metal or any conductive material to the battery terminals is extremely dangerous and will damage the battery. Warning: An attached trickle charger is ONLY intrinsically safe when connected as described in the electrical diagrams in section 12. Warning: Listening to EXO's siren at high volume for extended periods of time can cause permanent hearing loss. EXO's siren volume should be adjusted for use indoors and in smaller spaces. Wear appropriate ear protection during testing. Warning: Do NOT power off EXO if the blue LiveResponse light is on. Warning: EXO's sensors must only be zeroed with clean air. If a sensor is zeroed where its targeted gas levels are abnormal, the gas levels EXO displays will not be accurate. Inaccurate readings are a safety hazard. Warning: Off-scale (overlimit) readings may indicate an explosive concentration. Warning: Calibrations must only be performed in areas free of flammable gases. Warning: Gas notifications will NOT be generated during a purge. Warning: EXO Pump is not compatible with the following gases: Chlorine (Cl 2) and Chlorine Dioxide (ClO 2). Warning: If you start the pump while operating at temperatures of -20°C (-4°F) or lower, EXO will generate a pump blocked alarm (see section 10.4) that persists until the inlet warms up and begins operating normally. In a multiple inlet sampling cycle, the inlets do not have time to warm up. For temperatures below -20°C (-4°F), use only single gas sampling. Warning: When airplane mode is on, you cannot use the SOS latch or otherwise call for help using EXO. Warning: When Stealth is enabled, the lights will not flash, the siren will not sound, and EXO will not indicate incoming voice calls. Blackline Safety recommends that you have an alternative channel of communication available when EXO is in Stealth. Warning: Cables attached to the power port are only intrinsically safe when properly set up with an electrical barrier. Warning: EXO will NOT monitor when firmware is installing.
