10. If I put on my stereo headphones and insert them into the
phone’s headset jack, can I close the phone while I am
playing an audio (or video) clip without interrupting the clip?
Yes.When you insert your stereo headset into the phone’s headset
jack, the phone automatically goes into “headset mode,” allowing you
to close the phone and continue playing the clip. (Likewise, if your
phone is in “headset mode,” a phone call will not disconnect when
you close the phone.)
11. Can I surf to a different channel while I am playing a clip?
Yes.While you are playing a clip, you can use the up and down
navigation buttons to surf to a different channel.A small pop-up
screen will be displayed that tells you which channel you are
watching as well as other channels that you have access to.
Use the navigation buttons to scroll through the different channels.
Once you find a channel that you want to watch, scroll to it and
press
(or simply wait approximately three seconds), and the
channel will begin loading.
