Hi,
I received about 5 Sennheiser ew 135 G3 handheld mics and I am about to use them for the first time.
After gathering some info in the manual, I found out how to scan for frequencies etc.

MY BIG QUESTION IS:
I will be using the mics in a school with roughly 900 Students, how can I ensure a stable RF transmission
(with all those cellphones in the room) and Walkie-talkies (with run on 2.4 GHz so not a problem).
The scanning for frequencies will be done long before the 900 Students are in the hall, so I can't really check if the RF connection
is indeed stable or if there is any interference from cell phones.

I hope you guys can understand this problem, please tell me what I should do to get the best possible reception.
(I am just really nervous as this is the first time they are being used).


Cheers.

You need to be more aware of your local tv channels rather than cell phone use among your pupils. The rsm website http://www.rsm.govt.nz/cms/tools-and-services/publications/broadcasting/digital-television-channel-usage there is a spreadsheet of tv channel use across the country which will allow you to plot what tv channels are in operation and work around them. Depending on the tuning range, I would use the upper band which should be clear of tv services altogether. The 2.4GHz band is typically busy in urban areas so be warned. If you are in Chafee of any WiFi systems at school, then maybeyou can control what is going on in that band around the school hall?

What frequency range do the mics operate in and which area of NZ are you in?
