Stops while talking

Eventhough it is having enough battery, it stops while talking. I need to restart to get it operational and it takes quite some time to get back to operational mode.  Would be thankful if somebody provide me solution and mail it to

    You are describing my problem to a Tee. My Jam shuts off while I'm in a phone call. It is a two year old unit. It has the original battery. It shows adequate charge 50% or greater, when the condition appears. Today it shut off while on the phone, with a charge of 70%.

    I've seen this problem posted on many forums and no answer that states why the Jam dies while using the phone and does not exhibit similar problems as a PDA only.

    Me also have the same problem...

    I think the problem is due to battery life... If the battery is old the problem appears. But if the battery is new the problem disappears.

    Actually this problem occurs to My JAM when the battery reaches to around 50% then signal goes while I'm speaking. I exchange the battery with one of my friend's and the problem disappears. Now the problem appears again but when the battery reaches 30% and then increased to 40%.. I am assuming the problem is due to loss of battery life.

    I wonder if there is a way to calibrate the battery (Fully discharge then charge again.. Unfourtuantly I didn't find but please if any of you found HELP I am suffering. Otherwise I will purchase the 3rd battery!!!)

    Similar problem here. My I-mate Jam is about 4 years old with original battery inside and plays tricks sometimes... when battery is 50% or less then it may power off and won't power on until carger is plugged in. Also if battery is 50% or less, then it may loose network signal during calls. If the call is ended, the signal reappeares.

    I think it is an aging battery problem. I bought cheap replacement battery from Ebay, but it stopped working with two days... won't power on or charge. Now I am using old battery again. I am going to buy second replacement battery... see if it works.

Hi folks with aging JAMS. My JAM is still dying (complete shutoff) using phone. I wish it would just lose the phone signal but my unit shuts off completely during phone calls. I can have 80% charge. I spoke with a friend that mentioned on his cell phone (different manufacturer) that although his battery will show a full charge or less, the time it takes for the charge to go down is ridiculously fast once the battery is old. He watches his phone lose a charge in under an hour though it charges to full.

I wish IMATE would make some formal post regarding when to get a new battery and what symptoms are possible. I'm a bit hesitant to invest in batterys if the issue is hardware. I use the unit alot--as a PDA, a phone, etc. It gets jostled about so maybe something is lose inside, though I doubt it.

I purchased a cheap phone charger so in the car I'm recharging and at work I just keep a cheap USB to plug charger. I reserve the phone when I'm out. This is not really optimal for cell phone use but it's a behavioral fix. I figure I should be looking at a new device (despite high prices) soon.

I did a full discharge/charge cycle or two or three but only noted short term benefit. At some point the quirky behavior returned and off went the PDA cell with the 80% charge. I see dots of us around the net. Again my Jam is probably 3 years old this March.

Makita MAC5200.Brand new.Just broke-in. Pressure goes to 140 PSI and stops.Tries restart at 110 PSI.Motor"Humms"only.Will not restart until pressure below 20PSI.
There is a part called an unloader. It reduces the pressure on the compressor when the unit stops at the desired pressure. The actual unloader may be part of number 50 in this diagram.

2009 Chrysler town and country wont start.

Making several stops can cause the battery to be discharged to the point it will not restart the engine. Remember it takes about 20 minutes driving at highway speed to restore the power back to the battery it used to start the engine. Also, have your charging system checked for proper operation. Your alternator should charge between 14.2 to 14.8 volts at all times weather it is under no load or at full load to be charging at the optimal charge rate.

Garman 225w won't start, stops after "loading

The micro usb port is at the back. Connect Vehicle Power Cable to the nüvi and connect the other end to your computer, your nüvi does not operate as a GPS unit - it goes into some sort of charging mode. However, if you FIRST turn on the nüvi in the battery mode then go into the test mode (press the battery icon for about 8-9 seconds) from the main screen, THEN PLUG in the USB cable, and finally exit the test screen, your nüvi will restart (reboot) and it will operate just like it was plugged into the cradle connection in your vehicle.

This mode will charge the battery
AND operate as a GPS.

It works with my computer USB cable, my cell phone charger and my car charger for my cell phone.

Don't forget to turn off the nüvi before unplugging.
