5 beep-beep-beep-beep-beep [pause]
0 long-beep [pause]
low buzz [long pause / beeping complete] (NOTE: The RRC2+ repeats this sequence until you turn power off).
Ejection Charges and E-matches
The RRC2+ is designed to be used with low-current electric matches. These include Daveyfire, Oxral, MTEK, JTEK, or low
current motor igniters like the Quest Q2G2. Another common mistake made with altimeters and electronic deployment is
crossing up the drogue and main connections. Always double check your wiring to verify the drogue and main connections.
Final Assembly Testing
Once you've got your ejection charges connected to the altimeter and your av-bay is assembled, it's always a wise idea to
"pre-test" for continuity and avoid any surprises on the pad when the rocket is assembled and launch ready. Be sure that
prior to performing this test that you're safely clear of people, vehicles, or other flammable materials. Safety glasses and
other personal protection are also recommended. Be sure the charges are facing away from you and others, and then power
up the altimeter to assure everything is operating as you intend.

POST Mode Fault Codes
Codes are preceded by a very distinct warning tone (7 very quick low beeps), followed by the beeping/flashing of the fault.
DO NOT FLY THE RRC2+ until the fault or warning is resolved and corrected.
Code Fault
1 Ambient Barometric Fault / Unstable conditions during Launch Commit Test
2 Barometric sensor Fault / No communication reply
3 Barometric sensor Fault / Prom CRC Mismatch
4 Barometric pressure Fault / Pressure < 10 mbar or > 1200 mbar
5 Temperature Fault / Temperature < -40 deg. C or > 85 deg. C
6 I/O Line Fault

Handling Precautions

- Always handle the RRC2+ in a static-free, grounded environment
- Never touch/handle the RRC2+ when it is armed and connected to live pyrotechnic charges
- Always allow the RRC2+ to adjust to ambient temperature conditions prior to arming and flying
- Always prepare your rocket and recovery system components with the RRC2+ powered off
- Never cycle the RRC2+ power switch off, then immediately back on (allow at least 10 seconds).
