Hardware and Firmware Upgrade for V1000 Variometer

The new firmware version offers several new features:

• Compatibility with the PK312 9V Backup Battery Pack
  A hardware and software upgrade is required to all V1000 units with serial numbers before 060519 for compatibility with the PK312.  The hardware and software changes were necessary so that the V1000 can automatically switch itself off to conserve the battery if no altitude change is sensed over 2 hours. 
• New Sink Tone
  The sink tone now gets lower in pitch with larger sink rates.  The previous versions had a sink tone that increased in pitch with larger sink rates.  The climb tone remains the same as it has always been with increasing pitch with higher climb rates. The sink tone can be disabled if desired.
• Compatibility with FP10 Flight Pack

The upgrade must be done here in my office.  The price includes the cost of the new firmware chip, installation labor (circuit board change) and testing.  The price does not include shipping back to you.
