Max. respiration rate allowed (triggered hold-off time):
Fixed @ 30 BPM in R/M mode
Higher altitudes allow slightly higher maximum respiration rates (BPM):
0-10K ft. = 20 BPM, 12-20K ft. = 22 BPM, 21 - 25 = 25 BPM and 26+ = 30 BPM
Apnea time-out envelope:
Fixed @ 45 sec.
The apnea alarm does not respond if in any of the "D" modes and while below that pressure altitude threshold
Operating inlet pressures:
1 bar (15 psig.) DYNAMIC (flowing) through cannula and 1.5 meters (5 ft.) of 4 mm. inlet tubing
2 bar (30 psig.) STATIC (non-flowing) 2.2 bar (35 psig) MAX.
Operating Voltage & Current @ 25° C. @ 25% RH. (measured in "N" mode setting @ 15 RESP/ typical.):
Low-v. cut-out:
5.00 VDC+0 mv. -250 mv.
(red LED on steady)
Min.:
5.50 VDC @ 2.25 ma. idle (100 ma. peak, 3.25 ma. mean)

Low:
6.50 VDC @ 2.25 ma. idle (100 ma. peak, 3.25 ma. mean)
(Low batt. red LED winking 2/sec.)
Nom.:
7.85 VDC @ 2.25 ma. idle (100 ma. peak, 3.25 ma. mean)
Max.:
11.0 VDC @ 4.30 ma. idle (100 ma. peak, 3.25 ma. mean)
(EPS provides 10 VDC)
Reverse voltage protection:
Diode shunt (1 amp peak max., no internal fuse or over voltage protection provided)
External Power is provided via a 3.5 mm. coaxial power-jack system. Inside (tip) is negative (-) Outside (ring) is positive (+)
Battery Life:
Operating:
40 to 60 Hr's @ 25° C. @ 25% R.H.
Measured from mean, assuming fresh alkaline battery operating under normal operating conditions.
Storage:
Approx. 4-6 months while in the off setting. (battery drain is about 1 µa. in the off setting)
Make sure that the battery is removed from the unit during long-term storage.
Battery type:
Standard 9 volt alkaline DURACELL type MN1604 or equivalent.
Operating temperature and humidity (assumes nominal operating voltage):
Min.:
0% RH @ -55° C to +80° C.
Nom.:
25% RH @ +25° C.
Max.:
100% RH @ +50° C. near condensing
Allowable vibration during operation:
Random vibration 5 to 500 Hz, 15 minutes per axis @ 2.5 g. (rms.) sin wave;
