Optimised indication that can be understood clearly in all working conditions:
• The indicator light is visible in all usual workingenvironments, in sunlight or fog, with a wide visibilityangle.
• The 100 dB sound signal (from 1 metre) remainsaudible even over the noise of traffic or strong wind, thanks to natural conduction by an acoustic “horn”.
Direct access to the cell and sealed electronicscompartment. When the cell is replaced, this designprevents the following:
• accidental interchange of housing or circuitry;
• damage to electronic circuits;
• entry of humidity into the device when the cell ischanged outdoors.
