Problem
Error writing TeleMon data to
transmitter eeprom.
Malfunction in the %SpO
hardware, or transducer/adapter
cable damaged
Erratic %SpO measurements,
2
often due to a faulty transducer or
incorrect positioning of the
transducer
May also be caused by optical
shunting if sensor too big or too
small.
Level of ambient light is so high
that the %SpO transducer cannot
2
measure %SpO or pulse rate.
2
Transducer or adapter cable is
damaged.
May also be due to electrical
interference.
May also be generated by a
defective transmitter.
Corrective Action
Replace transmitter and contact
service.
Change transducer or adapter
2
cable.
If message persists, replace
transmitter.
Line up light source and
photodetector - they must be
opposite each other and light
must pass through the arteriolar
bed.
Reposition transducer to site
with higher perfusion.
Replace transducer or adapter
cable.
Use different sensor with correct
fit.
Cover sensor with non-white
opaque material (for example,
pulse oximeter probe wraps -
Posey wrap or equivalent) to
reduce ambient light.
If message persists, inspect and
replace transducer or adapter
cable as needed.
Reduce sources of electrical
interference.
If the above corrective actions
are ineffective, use a different
transmitter, and replace the
defective one.
