Info needed about Hema 5

Hi Hilary,

If the Hema5 is supplied with 12 volts from say the cigar plug and the cigar plug is fed from the ignition circuit (usual) then when you turn-off the car the Hema will continue to operate from its internal battery until that goes flat. So it is best to turn the Hema off when stopping the engine. (Hold down the Hema button until the screen goes blank)

If however you are only shutting the engine down for a short time (say less than a couple of hours) then it is sufficient to simply put the Hema into "Sleep Mode" by pressing the button for one second and it will display that is going into Sleep Mode before going blank. When ready to resume just press the button briefly and the Hema will resume to the screen that was last displayed. Saves going through all the boot-up procedure.

Hi Hilary,

As Alan has stated, there is a sleep mode on the Hema and when you turn the external 12 volt supply off the Hema will continue to operate uninterrupted from its internal battey.

I don't bother putting it in sleep mode if stopping for an hour or so. The internal battery should operate for around 4 hours when relatively new.

Reminds me of a task I have just completed on my Tomtom. The battery would not hold a charge for very long at all. The unit is approximately 3yo and the battery has just "died".
I ordered a replacement battery online from Battery Shack in QLD and have recently replaced the old battery with a new one. Not simply an unplug and plugin but the job turned out to be pretty painless and now Tomtom is as good as new.

Going to be interesting in 2-3 years when the Hema needs a battery transplant.

Hi Hilary,

If you have a dual battery set up, You could run a cigarette outlet from it into the cab and run your Hema off it.
