There is no time scale on how long before you "may" remind them. The word "may" is such that they can remind, but will not then be penalised themselves if they don't remind them (of something the other party SHOULD have done) hence it does not say something firmer like "shall" or "is obliged".
Equally you don't have to wait for them not to respond (two weeks) to a quote, and then wait a further period of reply before you notify their lack of response. If they have not responded within two weeks - notify immediately, and then they have a further two weeks to respond otherwise it will be treated as deemed accepted.
The three deemed acceptance loops within the CE process were introduced to stop a PM not responding and then the Contractor having no remedy. The longer it goes to get through the process, the longer it goes with NEITHER party understanding their respective liability.
