Charging the Battery
The Welch Allyn Vital Signs Monitor may be powered by either AC power or battery power after the
battery has been charged.
UPON INITIALLY RECEIVING THE MONITOR, CHARGE THE BATTERY FOR SIXTEEN (16) HOURS
OR UNTIL THE CHARGING INDICATOR LIGHT NO LONGER FLASHES. The battery is charged by
attaching the AC power transformer to the Monitor, and plugging the AC power transformer into the
AC mains power source.
While charging, the charging indicator will flash a yellow light. When the Monitor is fully charged
the flashing light will be replaced with a solid yellow indicator light.
Power On/Off and System Check Procedure
Each time the Welch Allyn Vital Signs Monitor is turned on, the unit performs an internal self-diag-
nostic check.
To turn the unit on, press the POWER button.
Upon power up, note that all of the LED segments in each display turn on briefly. An audible tone
should also sound. If the internal self-check is successful, the displays will assume their normal
functions and the monitor is ready for operation. If the self-check fails, an error code will be shown
in the displays.
To turn the unit off, press POWER button.
Note that turning the unit off will erase all stored blood pressure, temperature, SpO2 and pulse rate
data.
