Make sure all your firmware is updated, loaded properly and ready to go. Do a refresher course of the 2-way video available on the dealer site. Allow yourself enough time to get acquanted with the intricities of 2-way and be prepared to make several tweaks to get it the way you want. Also, be sure to have a good understanding of teh equipment your using, the features and the options available via 2-way.

Good Luck
