Firmware Upgrades

Whenever you send your RAD7 in for repair or calibration, you have the option of having the latest available software installed. Most RAD7's can be upgraded to the latest hardware configuration as well. You will be informed periodically of whatever new features are available for your RAD7. Please advise if you want to have an upgrade made. We intend to keep our RAD7 customers happy by keeping their instruments up-to-date and state-of-the-art.

Shipping Information

We recommend that you arrange for your RAD7 servicing ahead of time, to avoid possible delays. When sending your RAD7, please send the instrument only, without the accessorie, unless they are relevant to the problem.

Each RAD7 is originally shipped to in a plastic bag, packed in a box with "popcorn", and finally packed inside another box that also holds all the accessories. The inner box by itself is too small for the return trip, when you need a calibration or repair job. You will need to find a bigger box, with space for one inch packing all round the RAD7. A 14" cube box is fine. Pack the box well, with at least an inch of padding all around, and seal it carefully.

All return shipments to DURRIDGE must be prepaid, and unless you instruct us otherwise, we'll return it to you via the same shipping method you used to get it to us - from "slow boat" to "next day air" - freight collect.
