Once the Trend Display touch key icon is selected the trend data is displayed on the main
screen. The Radical stores one data set of SpO
2
, pulse rate, PI and system messages
in a dedicated memory area. Depending on the Trend Period, a setting for how often the
data is stored in the trend memory, the Radical can store between 87 hours and 18 days
of trend data. The Radical also employs a sophisticated data compression scheme. The
actual amount of trend data that is stored is dependent on the type of data that is
collected.
The Radical only stores data in the trend memory while the device is turned on, and the
trend data remains in memory until the memory fills up, or is cleared by the user.
CAUTION:
CHANGING THE DATE AND TIME OF THE SYSTEM CLOCK, OR
CHANGING THE TREND PERIOD, WILL ALSO CLEAR THE DATA IN THE
TREND MEMORY.
The following table outlines the trend capacity for sample Trend Period settings:
The Trend display can be configured to display any two of the three available trend parameters
(SpO
2
, pulse rate or PI). The unit is storing all 3 parameters in trend memory, but can only
disply 2 parameters at any one time. The Trend Display can be adjusted to the desired
parameter by Selecting
Trend from the Main, Display Menu.

The discharge cycle will take approximately 16 hours to complete for the Handheld
battery. The Docking Station battery will take approximately 30 hours to complete. A
message will appear in the service screen when the discharge cycle is complete. The
batteries will be fully charged after completion of the cycle.
When deep discharge is started, the backlight will automatically turn down to the default
handheld battery powered level. Wait until the message changes from (In Progress) to
(Done).
NOTE:
In order for the discharge cycle to be properly completed, AC power must be
supplied to the instrument throughout the cycle.
WARNING:
WHEN DEEP-DISCHARGING THE HANDHELD OR DOCKING
