Power supply
The M4/M4GPS is equipped with 2 batteries AA 1,5V type. On the welcome page, you can
check the batteries’ life. When the power becomes too weak, a message appears.
When this message displays, M4/M4GPS
goes automatically off after 10 seconds.
Remark :
Always check the batteries’ life before beginning a long session. The consumption and speed
of discharge depend on the quality and type of batteries, that’s why it is strongly
recommended to always check the batteries’ life icon on the welcome page. The GPS
module of the M4GPS, the intensity of the backlight and the LED brightness intensity
decrease the life of batteries.
Note: the GPS module requires +/- 40% of the system’s total energy to
function.
Batteries
The technology applied to our new systems requires larger battery consumption;battery
quality is crucial ! There are 3 major types of AA batteries on the market.
Salines :
Salines are rarely used, they only have about a third of the energy of Alkaline batteries.
Alkalines :
Alkaline batteries are the best option.
Rechargeable:
Very good option, but the qualities from a brand to another are important. A bad brand
loses its energy even with no use at about 1% a day. Furthermore, these batteries have a
memory effect, if you recharge a battery which is half full while in use, you will not be able
to use more than half of the stored energy, and the other half will be lost. There are very
good rechargeable batteries that even with no use only losses 12% during a whole year
and they don’t have a memory effect, you can thus use all the energy, these batteries were
used in our new systems with complete success.
Recommended examples of brands : SANYO Enellope XX and the UNIROSS Hydro, they are
more expensive but will give a lot of satisfaction; you can recharge them minimum 500
times. They are used in Professional photography.
