Page 38 DPM 8000 series - Technical Specification and Advanced Device Configuration
To recover a PIN/PUK the PUK2 is needed . PUK2 can only be created
by Service and Support Group in Vienna.
The user needs to contact his local dealer who then needs to create a
ticket in consol. In order to unlock the device with the PUK2 we need
the serial number of the device which can be found uderneth the
rechargeable battery – open the battery cover, remove the Li-Ion
battery and you see the full serial number.
(see picture) to ensure that the user is the owner of the device
therefore a purchase receipt needs to be attached to the tickes if this is
not available we need n declaration on oath from the user.
