i have done these things already. Thus my mild frustration with the whole thing
I hate to calibrate things without screen, *hmmm... if people asked what TM3 should have, definately some kind of screen..but who knows, it's expensive..
anyway, how to calibrate : (Thanks Tweakz)
“Please make sure that the screen is not falling on the heater.
You can adjust the temperature range easily:
1) first of all, remove the battery lid and insert it again to reset
the device
2) turn the temperature dial to minimum position
3) make a successful triple click as if you were trying to turn it on.
The.unit should give you short burst of vibrations and not start as
the temperature is set to the lock position
4) wait 2 seconds
5) repeat the triple click successfully, until you have done it
EXACTLY five times.
IF you were successful, the unit will start to vibrate continuously and you will have a white color of light coming from the back of the device.
6) Now turn the temperature dial to 0-10, when 0 -minimal temperature setting , 6 default , 10-maximum temperature , and turn on the device with a triple click.
7) To save this setting press and hold the button until all vibrations have stopped.”
