The Radical-7R Pulse CO-Oximeter Handheld includes a 1.5 Amp-Hour Nickel Metal Hydride
battery. The Radical-7R Pulse CO-Oximeter Docking Station may include the optional 6.5 Amp-
Hour Nickel Metal Hydride battery.
Before using the Radical-7R Pulse CO-Oximeter as a Handheld or transport monitor, the
Handheld battery and the optional Docking Station battery need to be fully charged.
To charge the battery(s), attach the Handheld instrument to the Docking Station. Ensure that
AC power is attached to the Docking Station. Verify that the battery(s) is charging; the battery
charging LED indicators on the Docking Station flash prior to charging and remain illuminated
while the battery(s) is charging. A continuously flashing battery charging LED indicates that the
internal battery temperature exceeds recommended operating conditions for proper battery
charging. Proper battery charging will proceed when the temperature returns to recommended
operating conditions.
The Handheld battery requires approximately 2 to 3 hours for charging. The optional Docking
Station battery requires approximately 6 hours for charging.
When the battery charging LED indicators turn off, additional trickle charging may occur to complete
charging. Although battery charging can occur while the Handheld is docked and powered on, most
efficient charge times are achieved with the Handheld instrument turned off.
CAUTIONS:
■
ALL BATTERIES LOSE CAPACITY WITH AGE, THUS THE AMOUNT OF RUN TIME
LEFT AT LOW BATTERY WILL VARY DEPENDING UPON THE AGE OF THE BATTERY.
■
AT LOW BATTERY CONNECT THE RADICAL-7R PULSE CO-OXIMETER TO AC
POWER TO PREVENT LOSS OF POWER.
During battery operation of the Radical-7R Pulse CO-Oximeter, please note that the following
operating conditions affect the estimated run-time of the included batteries:
■
VOLUME OF THE ALARM TONES. TO CONSERVE BATTERY POWER, KEEP THE
FREQUENCY OF THE AUDIBLE ALARMS TO A MINIMUM AND AT MINIMUM VOLUME.
Memory effects of the battery pack may shorten run-time. When battery run-time is significantly reduced,
it is advisable to completely discharge and fully recharge the battery pack. To properly discharge the
battery pack, use the Battery Discharge function as described in Section 4, under
Service
.
CAUTION:
■
IF THE RADICAL-7R PULSE CO-OXIMETER HANDHELD HAS NOT BEEN USED OR
CHARGED WITHIN SEVEN (7) DAYS OR MORE, THEN RECHARGE THE BATTERY
PRIOR TO USE.
■
IT IS RECOMMENDED THAT THE RADICAL-7R PULSE CO-OXIMETER HANDHELD IS
DOCKED TO THE DOCKING STATION ATTACHED TO AN AC POWER SOURCE WHEN
IT IS NOT IN USE TO ENSURE THAT THE BATTERY REMAINS FULLY CHARGED.
The following tables outline the estimated run times of the battery powered Radical-7R Pulse
CO-Oximeter. The time estimates are based on a Radical-7R Pulse CO-Oximeter with fully
charged batteries. The Radical-7R Pulse CO-Oximeter is always configured to include the
Handheld battery. It may optionally be configured to include the Docking Station battery. Please
determine the configuration of your system before referencing the following tables
