Initial Set-Up Operation
2 - 4 0070-10-0603-01 Duo™ Operating Instructions
NOTE: The Lithium Ion battery is shipped in a partially charged
state and must be fully charged prior to its first use.
3. Charge the Lithium Ion battery as follows:
• Connect the AC power cord to the AC receptacle located on the rear panel.
• Plug the opposite end of the AC power cord into the appropriate AC outlet. The
Battery Charging indicator will be illuminated on the front panel.
• Allow the battery to charge for a minimum of 4 hours.
NOTE: Optimum battery runtime is achieved after 3 charge/
discharge cycles.
4. Power ON the Duo by pressing the Power ON/OFF key. A single beep tone
indicates that the Duo has successfully powered ON. An internal diagnostic test and an
LED test are then executed. For the duration of the tests, all operational LEDs are
displayed and the number “8” (plus any decimal LEDs) is displayed in the parameter
tiles. When the tests are successfully complete, the following LEDs remain displayed:
• AC Power indicator (if AC power is present)
• Battery Charging indicator (if the battery is installed and AC power is present)
• Patient Size indicator (the current setting)
• Unit of Measure indicators (the most recent settings) for NIBP, Pulse Rate and SpO
2
(optional)
If any portion of the internal diagnostics test fails, error codes are displayed in specific
parameter tiles as described in "Information Codes and Error Codes" on page 2-13.
2.2.1 Setting the Units of Measure (Units of Measure Mode)
The NIBP parameter has 2 choices for the unit of measure. This setting is maintained after the
Duo is powered OFF. The units of measure for Pulse Rate (bpm) and SpO
2
(%) are not
adjustable.
• The NIBP units of measure are mmHg and kPa.
The default setting is mmHg.
