BeeEss, I take it you finally took the plunge and bought a Zen 2.0. How do you like it so far?
The remote for the Zen doesn't let you control the unit as much as say the one for the iRiver iHP. However, it is still quite powerful and pretty useful if you keep your Zen in a bag or on your belt, like do.
First, you should set up your playlist/now playing queue using the main unit as you can't do that with the remote.
You can use the remote to power up (holding down play/pause when the Zen is off) or power down (holding down stop when the Zen is on).
When playing tracks, the remote does all the basic stuff like play, pause, stop, forward, rewind, and volume asjustment. You can also turn the EAX on and off but can not change it (you'll need to go to the main unt for that).
With the radio, you can store up to 30 FM channels.
With the voice record, you can store up to 10 hours at a time. Hold down play (for a couple of seconds for it to start) and hold down stop to save your voice file. You can also use the remote to playback the last voice file you recorded. You'll have to use the main unit to delete files and to adjust the recording gain.
The remote also has a lock button in case you accidently press any keys.
Not to alarm you, but my original remote recently shorted out (after about 2 months of usage) and I just received a replacement one this week. For some reason, everytime I moved the wire a certain way, it would cause the music to jump and flicker.
*****
As for stopping a track with the main unit, yes there is no stop button. You really don't need to fully stop a song since the Zen is playing a digital file from memory and hitting pause is just like a stop button.
However, to fully stop a track you press 'pause' and then press "reverse" or "forward." If you press reverse, then the Zen will will stop at the beginning of the song you were just listening to. If you press forward, then the Zen stops at the beginning of the next song (normal play) or a random song (shuffle play) in your play queue.
I hope that helps you out.
Good luck!
