6. Press the Backlight/Recall button once to advance the display to the probe type identification test. At
this point, probes can be installed or removed. Oral probes should produce the “OrL” display, while rectal
probes should produce the “rEC” display. When no probe is installed, the display is blank (except for the
flashing M). A calibration key, when plugged in at this time, looks like no probe is plugged-in.
7. Press the Backlight/Recall button once to advance the display to the software revision. The display
should show “r X.X” where “X.X” is a number such as 1.8. This can be helpful when discussing
operation with Welch Allyn customer support.
8. Press the Backlight/Recall button once to advance to the repeating display test. This is the same display
test as initiated when batteries are first installed. Each segment of the timer is incrementally turned on
while each segment of the remainder of the display is individually lit. Following this, all segments are lit
briefly and then the test repeats.
9. To repeat the sequence of displays in Biotech mode, press the Backlight/Recall button during the display
test when all segments are on.
10. To exit biotech mode at any time, switch to Normal mode. On exit, probe initialization will be started.
If you cannot enter the Biotech mode, refer to the
Biotech Mode Problems
section of the
Troubleshooting
section on page 22.
Battery Life
Under normal use, battery life is expected to give up to 6,000 temperatures. This number is based on a
22.2
°
C (72.0
°
F) ambient temperature and 15% backlight use. Colder ambient temperatures, excessive
backlight usage, use of non-alkaline batteries, and other usage patterns can reduce battery life. Instruments
are shipped with fresh batteries, but we cannot guarantee full life from the first set of batteries due to
potential long storage times between shipping and actual use. Battery life can also be reduced by storage at
elevated temperatures.
If you are experiencing short battery life, refer to the
Battery Life Problems
section in the
Troubleshooting
section on page 22.
