# Service bulletin SIL\-3112

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Altec has learned that on certain digger derricks built from January 29, 2015, to December 3, 2020, equipped with a Hetronic radio control system have experienced frequent dropouts or would not connect to the receiver. When the remotes were tested, the radio firmware was found to be at fault. Hetronic has released a new firmware update for radios built beginning in January 2015 that can be flashed onto the radio by Altec Service Technicians.
