Displays, Indicators, and Controls
Pulse Strength Bar Graph LED
This 8-segment tricolor bar graph indicates pulse strength as determined
by the oximeter. The bar graph changes color based upon the strength of
the pulse. The color and height of the Pulse Strength Bar Graph is
proportional to the pulse amplitude. For low pulse amplitude, the device
goes into High Priority Alarm mode:
Green
= a good pulse strength
Amber
= a marginal pulse strength
Red
= an inadequate pulse strength, high priority alarm
The Pulse Strength Bar Graph LED also indicates the battery capacity in
12% increments in green. Amber represents the depleted capacity of the
battery and green indicates the available battery capacity.
Alarm Silence LED
This amber LED indicates that the audible alarm is silenced for 2 minutes
when it blinks. When lit solid, the Alarm Silence LED indicates that the
audible alarm volume is set to less than 45 dB.
AC Power Supply LED
This green LED is displayed when an external power supply is providing
power to the Avant 9700. Any time this LED is displayed, the battery is
charging.
NOTE:
When the external power supply is disconnected, the device
automatically switches to battery power without loss of functionality.
Battery LED
This amber LED indicates marginal battery capacity when blinking. When
solidly lit, the LED indicates that the battery pack is not installed.
This LED
does not indicate that the device is running on battery power.
New battery
packs must complete one charge/discharge/recharge cycle before the
Battery LED displays the actual capacity.
WARNING: The battery pack must be installed at all times while the device is
operating—even when operating on AC power. The audible alarms and memory will
not function if batteries are removed from the device. DO NOT use this device without
batteries.
