To deep discharge the optional Docking Station battery, select this
menu item. See Section 9, Battery Operation and Maintenance, for
more information.
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 sup-
plied to the instrument throughout the cycle.
Trend Display
Once the Trend Display touch key icon is selected, the trend data is displayed on the main
screen. The Radical-7 Pulse CO-Oximeter stores one data set of SpO
2
, pulse rate, SpMet,
SpCO, 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-7 Pulse
CO-Oximeter can store between 72 hours and 18 days of trend data. The Radical-7 Pulse
CO-Oximeter 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-7 Pulse CO-Oximeter 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 CHANG-
ING THE TREND PERIOD, WILL ALSO CLEAR THE DATA IN THE TREND
MEMORY.
The following table outlines the trend capacity for sample Trend Period settings:
TREND PERIOD TREND MEMORY CAPACITY
2 SECONDS
MINIMUM OF 72 HOURS (3 DAYS)
10 SECONDS
TYPICALLY 435 HOURS (18 DAYS)
The Trend Display can be configured to display one or two of any of the five available trend
parameters (SpO
2
, SpMet, SpCO, pulse rate or PI) that are selected by the user. The unit
is storing all 5 parameters in trend memory, but can only display one or two user selected
parameters at any one time. The Trend Display can be adjusted to the desired parameter
by Selecting Trend from the Main, Display Menu.
WARNING: WHEN DEEP-DISCHARGING THE HANDHELD OR DOCKING STA-
TION BATTERY, MAKE SURE THAT THE DEVICE HAS BEEN
REMOVED FROM SERVICE UNTIL FULL BATTERY CAPABILITY
CAN BE RESTORED.
