Capnostat 5 sensor.
• R Series unicables and R Series electrodes. The fully featured models support defib, pace, CPR, date code, condition sensor, defib self-test while pre-
connected, and monitoring while pacing.

Power Management Support Functions
Charger Functions
When battery is fully charged, the charge current is terminated by setting the charger current PWM to less than 15%. The charger resumes supplying
battery current when the SOC reaches 95% +/-1%.
R Series powers on when a battery is dropped-in if the loaded battery Voltage is above the hardware threshold (8.7V). Upon battery drop-in, charger
current-limit is established on the basis of Battery conditions and DC bus Voltage. If the battery charge was recently terminated due to over-current, the
charger FET is opened, and the replace battery is indicated.
Shut-down Functions
The software initiates the shutdown sequence (“replace battery”) when the Kelvin Battery A/D Voltage is 9.3V or at 600mA-hrs of remaining capacity,
whichever occurs first. (Remaining capacity is read from the battery as a 16-bit unsigned quantity directly in mA-hrs).
The hardware will not shutdown if the input Voltage (at the switched-power node) is above 8.7V.
The software initiates “low battery” at an RTTE (run-time-to-empty) of 65 minutes. This is designed to allow 25 minutes of run-time until "replace
battery" under nominal R Series operating conditions in monitor mode with no printer.
If the system shuts down due a slowly depleting battery, the R Series system requires user-intervention to turn back on. This could be due to battery drop-
in or the front panel switch.
