Power supply
The M4/M4GP 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/M4GP
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 GP
module of the M4GP , the intensity of the backlight and the LED brightness intensity
decrease the life of batteries.
Note: t e GPS module requires +/- 40% of t e 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, t ey only ave about a t ird of t e energy of Alkaline batteries.
Alkalines :
Alkaline batteries are t e best option.
Rec argeable:
Very good option, but t e qualities from a brand to anot er are important. A bad brand
loses its energy even wit no use at about 1% a day. Furt ermore, t ese batteries ave a
memory effect, if you rec arge a battery w ic is alf full w ile in use, you will not be able
to use more t an alf of t e stored energy, and t e ot er alf will be lost. T ere are very
good rec argeable batteries t at even wit no use only losses 12% during a w ole year
and t ey don’t ave a memory effect, you can t us use all t e energy, t ese batteries were
used in our new systems wit complete success.
Recommended examples of brands : SANYO Enellope XX and t e UNIROSS Hydro, t ey are
more expensive but will give a lot of satisfaction; you can rec arge t em minimum 500
times. T ey are used in Professional p otograp y.
