Service Announcement for Spektrum Module Users
Simple fix for module “Shut down” issue
A few of our customers are experiencing a “shut down” condition with their Spektrum module systems. A “shut down” can occur in a hard crash, or while running in a specific area of the track. It is characterized by a loss of power to the servos. To reactivate the system, it is necessary to turn the receiver off, and then back on again to resume normal operation. Shut downs are most prevalent when racing on carpet due to static electricity, however they can also occur on any surface during a hard crash.
This issue is not a related to DSM technology, but is a result of an improperly routed antenna inside the module, which causes a compromised link quality. If you’ve experienced a “shut down”, please return your module to Spektrum’s service center for quick repair, which involves installing a new, longer internal antenna wire with the correct routing. While this issue affects relatively few modules, you can easily check your module to determine if your system has the proper routing - refer to the instructions below.
We apologize for this inconvenience. We are committed to achieving perfect reliability and your total satisfaction with Spektrum products.
HOW TO CHECK YOUR MODULE
Using a Phillips screwdriver carefully remove the case from your module and examine the antenna connection to the board:
Note: See attachments below
Correct - Note the antenna coax is routed under the main radio board.
Incorrect - The antenna coax is routed over the board in close proximity to power capacitors and IC’s compromising signal integrity. Please return to Spektrum for service. In the case of Futaba Hitec modules, a longer antenna wire will be needed.
