How Does the SmartMonitor 2 Work?
The SmartMonitor 2 may also alarm if there is an internal system error. If your monitor alarms and the lights are not
illuminated, or if all of the lights are blinking on and off, look at the LCD display on the bottom of the unit. If there is an
internal error, a code will be displayed. Discontinue use of monitor and contact your health care dealer.
