Features
Controls
All functions of the Model 8500V series are controlled by switches found on the front of the unit.
Power
Pressing the "1" switch causes power to be applied to all the internal circuitry upon actuation. The "1" switch has
additional clock and printer mode setting functions when used with the arrow switch. The "0" switch causes power to
be removed from the displays and puts the oximetry circuitry into a low power standby mode when pressed. The clock
continues to function in the low power standby mode (when enabled). In order to conserve battery life, the 8500AV
will shut itself off after 10 minutes of inactivity. Inactivity is indicated by dashes in the displays and is caused by:
•
no sensor connected to the 8500AV oximeter
•
the pulse is too low
•
the sensor is not attached to a patient
Each time a reading is displayed, the 10 minute timer is restarted.
Audible Heart Beat Tick or Display Intensity
On the 8500AV, the arrow switch causes the Audible Heart Beat Tick to toggle status on or off. The arrow switch has
additional clock and alarm mode setting functions when used with the "1" switch.
Setup Mode
Setup mode is used to control the options of the 8500AV oximeter. These options include time-of-day clock and alarm
settings. The setup mode is initiated by holding the arrow key when the unit is turned on by pressing the "1" key. In
setup mode, the "1" key and the arrow key are used to make the selections. The "1" key is used to advance to the next
setup entry and the arrow key is used to advance the optional value for this entry.
Alarm Settings
"
Alr
" will appear in the left-hand display, indicating the Alarm mode. "
dft
" will appear in the right-hand
display. Each time the arrow switch is pressed, the option on the right-hand display will advance. When the correct
value appears in the right-hand display, pressing the "1" switch will advance the left-hand display to the next
parameter listed in Table I. If the "
OFF
" option is selected, then the alarm functions are disabled and the setup
skips immediately to the printer/clock setup. If the "
dft
" option is selected, then the standard default values are
loaded into memory, but if the "
rcl
" option is selected, then the previous user programmed values are reloaded.
These values may be changed with the remaining alarm setting entries. This process is continued until all alarm
parameters are set. When the alarm setting sequence has been completed, the 8500AV continues to the printer and
clock settings (see below).
Printer and Clock Settings
"
Prn
" will appear in the left-hand display, indicating print setup mode. The "
Prn
" mode is currently not used.
Advance to the clock setting mode by pressing the "1" switch. Each time the arrow switch is pressed, the number
on the right-hand display will increment. It starts with the current value for the parameter currently stored in
memory. When the correct value appears in the right-hand display, pressing the "1" switch will advance the left-
hand display to the next parameter listed in Table I. This process is continued until all parameters are set. The
settings can be checked easily, since the first value displayed for each parameter represents the current setting.
When the setting sequence has been completed, the 8500AV exits the clock setting modes and begins normal
operation.
NOTE:
Setting the month to
00
disables the clock function and helps conserve battery life.
