Service Manual

Troubleshooting

Certain conditions may evoke special messages in the saturation and pulse rate displays. These

displays and the conditions are listed below. Note that “Err” stands for error, but does not

necessarily indicate a malfunction. Also, error conditions one and two are internal only, and are

not displayed.

Low signal strength. Pulse strength as detected by the sensor is too small

for proper monitor operation. This message will disappear once the prob-

lem is corrected.

Insufficient light. Sensor is placed on a site too thick (or opaque) for ade-

quate light transmission. This message will disappear once the problem is

corrected.

Pulse out of range. Pulse must be within 30 -250 beats per minute inclu-

sive. This message will disappear once the problem is corrected.
