![DBI-TX1 User Manual Issue US3 Page 4/12 1. Description 1.1. General • The DBI-TX1 is a wire less transmitter monitoring free hot air balloon envelope top temperature. It transmits data to the DBI-002 flight instrument where temperature is displayed. • The unit consists of a sturdy aluminum enclosure fitted with a load tape slot attachment, exiting antenna and temperature probe wires. • The unit is power supplied with a replaceable long life lithium battery. Battery replacement interval is typically four years. • Power on/off is controlled automatic by the difference of box (outside envelope) and temp probe (inside envelope) temperatures. No operator action is required. • Each unit has a unique serial code that is matched with the receiver DBI-002. DBI-002 data reception is qualified by serial code and comprehensive transmission error detection. • Short duty cycle and low RF power data transmission enables interference free operation and multiple units to operate in close proximity. • Conforms to FCC part 15.249 • FCC approval identification: TDJGC132926](https://usermanual.wiki/Digitool-Instruments/GC132926.transmitter-dbitx1-user-manual/User-Guide-565432-Page-4.png)

DBITX1 identification code programming Program the DBITX1 identification code to the DBI-002 flight instrument by using the DBI-002 PC application software. Refer to “DBI-002 User Manual”. 4.3. Power On / Off The power on / off is automatic: • The DBITX1 will start transmission when a temperature difference between the box and the temperature probe is greater than 10 °F. • The DBITX1 will stop transmit after 5 minutes when a temperature difference between the box and the temperature probe is less than 10 °F. • For permanent power off, remove internal battery coin cell. See “5.2 Battery replacement”.](https://usermanual.wiki/Digitool-Instruments/GC132926.transmitter-dbitx1-user-manual/User-Guide-565432-Page-10.png)
![DBI-TX1 User Manual Issue US3 Page 11/12 5. Maintenance 5.1. Battery (Lithium cell) replacement • During normal operation, the internal battery will last for typical 10 years. Recommended replace interval is 4 years. • Replace battery if DBITX1 does not operate properly. Unmount the top lid attached by the two bolts. Unmount CCW. Replace the coin cell: • Replace type is “CR2450”. • Positive terminal facing up. • Inspect for clean battery holder metal surface. Clean with soft cloth if dirty. Mount the top lid: • Make sure seal is correctly placed in lid groove. • Tighten bolts firmly.
