Some cellular service providers limit the types of files that the phone will
transfer, even if the phone has greater capabilities built into it. Contact the
service provider if you feel that a phone’s functionality is being limited.
7. Why can’t I view an image on my phone even though I can view images from
larger files?
Some phones don’t only care about the size of the file in bytes, but they also
care about the size of the image in pixels. A large 1500 x 1500 pixel image
might compress down to 80 kB using a high compression algorithm, whereas
a small 700 x 700 pixel image might only compress to 100 kB using a low
compression algorithm.
Even though both files have a low number of kilobytes and may be accepted
by a phone, some phones might not display the large 1500 x 1500 image.
8. After downloading the flyer in Passive mode, I cannot immediately download
it again, but if I wait a while, I can download it again later. Why?
In Passive mode, the unit will download the flyer to the same device as many
times as requested, though it does have a 90 second timeout. After a device
has downloaded the flyer, it will not send it to that device again for 90
seconds. This is to prevent unintentional duplicate requests by consumers.
9. Why can’t the Compact Flash card be removed from the front of the unit?
The Compact Flash card is not removable.
10. How is an audio recording made?
Audacity, a free recording application, is distributed on the BlueFlyers’
installation CD. This tool or other applications may be used to create
recordings. The BlueFlyers Wizard does not record audio itself.
11. How is a quality sounding recording made?
Be sure to use a quality microphone and a pop screen to get clean, crisp
audio free of wind noise, and smile when speaking to have a bright sounding
voice.
12. Where do I get the LAME MP3 encoder needed by Audacity?
