n Specifications
When ordering our products, specify them with an “Ordering Code” that consists of the following:
–M
Model name Frequency (up to 9 digits) –Number for specifying an order
If you have any queries concerning our standard frequencies and numbers for specifying orders, please contact our sales representatives or visit our homepage (http://www.ndk.com/).
