ERASING TREND MEMORY
To erase (clear) the trend memory, turn the trend off and back on again. Enabling trend
(setting Trend to “ON”) will erase all trend data.
NOTE: Turning trend off will not erase trend memory. You may turn trending off and still
retrieve the trend data using TrendCom.
Turning the Rad-57 off or replacing the batteries will not erase the trend data.
Turn trending off before storing the device for any length of time.
TREND DATA FORMAT
After a successful download of the trend data, a .out file will be created containing the trend-
dump information in ASCII delimited format. The format is defined in the following table.

Exception
Messages
The exceptions are displayed as a 3 digit, ASCII encoded, hexadecimal
value. The binary bits of the hexadecimal value are encoded as follows:
000 = Normal operation; no exceptions
001 = No Sensor
002 = Defective Sensor
004 = Low Perfusion
008 = Pulse Search
010 = Interference
020 = Sensor Off
040 = Ambient Light
080 = Unrecognized Sensor
100 = reserved
200 = reserved
400 = Low Signal IQ
800 = Masimo SET. This flag means the algorithm is running in full SET
mode. It requires a Masimo sensor and needs to acquire some
clean data for this flag to be set.
