M3PO go
The batteries.
Not hard to guess and discernable from the package content, the M3PO go runs on batteries,
to be exact, on 2 of the type AA (Mignon). You can use disposable as well as rechargeable
batteries. Freshly stocked up, the M3PO go offers up to 7 hours continuous playback, using
rechargeable batteries reduces the playtime a bit.
When you know you are not going to use the player over a longer time period or you run it with
the included power supply adaptor cable, you should pay attention to take the batteries out
of the device. Rechargeable batteries can't be recharged over the power supply.
Please never throw a battery into an open fire or expose them to extreme heat. There is danger
of leaking and explosion. When they are empty, please pay attention to only use approved
disposal methods.
Energy Use.
Very important for mobile devices like the M3PO go: playtime when using batteries. Basically
you can say that the playback of MP3 CDs is not only more comfortable than that of audio
CDs, but also uses less electricity.
For playback of MP3 CDs the M3PO go - as you can see for yourself when it's running - takes
the following form: after pressing PLAY, the CD runs for a short time and a part of the MP3 file
gets read into the anti-shock buffer. When the memory is sufficiently filled, the CD stops and
the data gets read out of the memory. If the data stored in the memory comes close to running
out, or the title gets changed, the CD kicks on again and the game starts over. So the drive
motor turns only from time to time, which noticeably reduces the energy usage. This simple
but efficient tactic not only saves energy, but also protects against unwanted skips, because
shaking the player doesn't affect the playback out of the memory.
The memory of the M3PO go isn't unlimited, however, and with a little math you can see that
for MP3 files with high bit-rates (more data), the memory has to be “refilled” more often com-
pared to low bit-rates, because for the same play time a lot more data is present. That means
that the drive mechanism has to work more, which raises the energy usage and reduces the
total playtime. This should be taken into consideration when you create (encode) your MP3
files. Here again, less is more.
An equally energy saving function is the lack of background light when running on batteries.
This only works with when using the power supply. Furthermore, the player shuts off auto-
matically after ca. 1 minute when nothing is played and no button is pressed.
