Things to Know Before you Buy

Amplivox requires a code for calibration

Amplivox requires a code for calibration for technicians to gain access to perform calibration.  While these are calibrated when sold through Oaktree Products, the code is not made available to Oaktree Products at the time of sale. When the time comes for the annual calibration, a code is required to initiate the process.  If you are in need of a code, Oaktree Products is more than happy to work on your behalf.   Contact Oaktree Products with the serial number of your Amplivox unit; we will contact Amplivox, obtain the necessary calibration code, and forward the information directly to you. The calibration code should be valid for the lifetime of the device.
