Warranty, Service and Parts

Authorized Service and Replacement Parts for Rhythmedics Instruments

All NuTesla Rhythmedics instruments are warranted to be free of manufacturing and material defects for one year from the date of purchase.  Your instrument is automatically registered when purchased; there are no warranty cards to return. 

Pendulum PlusLi Upgrade, Replacement Power Adapter, Programming and Power Cable and 12V USB Dual Port Car Adapter are available for order at the bottom of this page

During the warranty period all software upgrades and updates are provided through the Instrument Console webpage at no charge for the customer to download, unzip and transfer to the Rhythmedics flash-drive as instructed on that webpage. Additional and Custom Wellness Preset Programs for purchase are available here.

If your instrument is covered by an original or extended warranty and is not operating properly please contact NuTesla Support either by leaving a voice message on 1+(910) NUTESLA (688.3752), or by sending an email to support@nutesla.com. Do not send your instrument to NuTesla before receiving a Support Authorization Number (SAN) to ensure your instrument service is handled quickly and securely.

It is the responsibility of the customer to properly pack and ship an instrument to NuTesla for repairs. A padded mailing envelope provides adequate protection from damage during transit. DO NOT RETURN THE USB POWER ADAPTER OR CABLE WHEN SENDING YOUR INSTRUMENT IN FOR REPAIRS.

If your warranty has expired, NuTesla offers three options to assist you.

Option 1 – One Year Warranty Extension ($47 for US, $57 for Non-US)

Select this option if your instrument is working and you have either a Windows or Linux PC for performing updates yourself. This will renew the warranty for one year from the date the extension is purchased and provides you access to the latest firmware updates and preset programs. If your instruments fails during the extended warranty period NuTesla will either repair or replace your instrument for only the cost of mailing the instrument to NuTesla support.

The USB power adapter and cable are not covered by extended warranties. They are both industry standard Mini-B adapters and readily available at most electronics stores or by ordering at the bottom of this page.

NOTE: When purchasing a warranty extension you must first connect your instrument to a computer with a working USB port and Internet connectivity, and press and hold the SETUP or START dome switch to activate the internal Rhythmedics flash-drive. Once your instrument is enumerated as a flash-drive, open the NUTESLA.HTM file in your default Internet browser (e.g. Chrome, Firefox, Safari, IE, etc.) and note and record both the current firmware version and Serial Number for your Instrument, which must be entered when purchasing the warranty extension.

IMPORTANT NOTES REGARDING REPAIRS AND WARRANTY EXTENSIONS

To extend your instrument’s warranty and optionally have it updated or repaired select the appropriate option above and complete the purchase. For customers served by the US Postal Service, NuTesla offers a prepaid mailer service for an additional $10, as available in the options above. If the prepaid mailer option is selected, NuTesla will send you a padded mailer with a preprinted, prepaid address label for sending your instrument to NuTesla’s service center. For shipments outside the USA a phone number is required and the customs declaration must indicate it is an item being returned for repair and the country of origin is the US.

If you purchase either Option 2 or 3 above, NuTesla support will contact you via email with a Service Authorization Number (SAN) to be included on the shipping label to NuTesla.

Do not send your instrument to NuTesla for servicing without first receiving a Service Authorization Number (SAN) from NuTesla. Contact NuTesla support either by leaving a voice message on 1+(910) NUTESLA (688.3752), or by sending an email to support@nutesla.com. Once you have received a Service Authorization Number (SAN) and the appropriate service center address for your instrument, properly pack the instrument to prevent damage in transit and only ship with a tracking number, such as USPS Delivery Confirmation. The label must include the Service Authorization Number (SAN).

Unless the prepaid mailer option is purchased it is the responsibility of the customer to properly pack and ship the instrument to NuTesla for repairs with the SAN marked on the label. NuTesla will pay for the return shipping of the instrument to the customer.
