Note on Firmware Versions
This manual is based on version r204 of the Ersky9x firmware, issued in
May 2014 and installed in production models of the 9XR Pro with serial
number 3001 or higher. Radios with serial number 1-3000 come equipped
with version r202. The only significant difference is that r202 does not
include the Latch and Flip-Flop functions, documented in this manual on
page 34, or the default of eight voice switches in the Safety Switches menu
(see page 36).
To check your version number, see page 14 of this manual. Instructions for
flashing an update can be found in the manual Communicating with a
Computer. If you use the eepskye program on your computer, it can
automatically check for updates and download the latest file ready for
flashing.
The latest firmware file can be obtained from:
