Send us your eMotimo Spectrum ST4 to be upgraded to the ST4.3. Choose the basic upgrade, or upgrade and add an additional 6 months to your warranty. For timing expectations, we will need your unit from 5-9 business days in our San Diego shop.
1) please make sure you have registered your eMotimo ST4. This is required.
2) Purchase the upgrade option you would like. The shipping cost is calculated for your return shipping.
3) Wait for instructions from an agent in our help system. We will be reaching out with questions, instructions, and scheduling. We will typically reach out in a business day or less.
