I have two cases. One involves a touch panel for user input. Marketing
types say they cannot sell a touch panel that takes more than a second
to respond. The second case involves a wireless (2.4 GHz) function.
Again the marketeers say that they cannot sell something that takes 20
seconds to wake from standby. So where or how does one justify that?
It seems obvious to me that those delays are not appropriate for
intended use.
And how does one get that justification "approved"?
I don't think you have to; you just document it.
Continuing, how does one write the DofC? Do you include the
Directive/standard
Yes.
used to show compliance and add a statement that ErP is inappropriate?
I don't think you can, or need to, put 'excuses' on a DoC.
Or does one just leave the ErP Directive/standard out of the DofC
completely?
Not if the Directive applies; that would be a violation.
In a variation of the wireless case, consider wireless audio. The
receiver never knows when a user will send audio to the receiver. So
the receiver must be on all the time to be able to play that incoming
audio whenever the user requests it. But when the wireless is on, the
unit cannot consume less than the proscribed 0.5W. Close, but no cigar.
So in this case, can we say the unit is on all the time and we have a
manual (means to go standby or off)?
Yes.
And that there is no automatic means to go standby or off because the
radio is always listening for the incoming signal? Is that compliant
with Phase 2?
Yes.
Consider how like your products are to a clock. Clearly, it cannot be
fully on only when someone is looking at it.
When people with the privilege of actually asking the Commission people
about 'grey areas', they reply, 'We never write Directives that result
in an anomalous or unreasonable requirement. If you think we do, you
haven't understood the Directive.' You can, of course, choose whether to
believe that.
