e) Electromagnetic Disturbance (EMI).
i) The device’s performance must not be influenced by EMI emitted or conducted with the high-voltage line from one more tool.
ii) If the system is impacted, it should fail securely.
f) Alarms.
i) The unit needs to have visual or audible alarm systems to advise drivers of any kind of system fault that may trigger harmful or erroneous results.
ii) Audible and/or aesthetic indications ought to trigger when the screen reading gets to and stays at the alarm system restriction.
iii) All alarms must be totally explained in the driver’s handbook.
g) Audible Alarms.
i) Audible alarms need to be distinct as well as easily identified.
ii) Distinct alarm systems must be enabled when the unit is activated (i.e., the default volume need to not be set to OFF) as well as should be clearly audible at any kind of quantity setting.
iii) If the alarm system quantity is flexible, it should not be possible to turn the volume down so reduced that it is not most likely to be heard.
iv) Although an audible-alarm silence is acceptable, the alarm should reoccur automatically if the condition is not remedied.
v) If an alarm is silenced, a visual display ought to plainly indicate which alarm system is handicapped.
h) Visual Alarm systems.
i) Visual alarm systems ought to be simple to recognize.
