4. DISPLAY AND OPERATION
The monitor displays three main screens: the monitoring, system setup and trend graphs.
The front panel controls operate the monitor on these screens. For more details, please see
below and refer to Fig. 1.
4.1 Power On/Off
Press the power button and hold for more than 3 seconds to turn on the monitor. The green
LED on the front panel lights up. When the monitor is on, press the power button to turn the
monitor off.
NOTE
The monitor is powered either by the built-in rechargeable battery or external AC power
supply. If not connected by the external AC power supply and the battery hasn’t enough
charge, the monitor may not turn on. If this happens, connect the external power supply to
charge the battery. The monitor will operate on the battery again after the battery is fully
charged. The battery charges automatically whilst connected to the external power supply.
If the SPO2 sensor and the TEMP cable are disconnected, or if the TEMP cable becomes
disconnected and the SpO
2
sensor stays connected but the finger is removed from the
sensor, the monitor automatically enters standby mode. In this mode, when the SPO2 sensor
is reconnected and a finger is inserted into the sensor, or the TEMP cable is reconnected,
the monitor automatically resumes operation; otherwise the monitor automatically shuts
down in 3 minutes.
4.2 Change Display Modes
The LCD initially displays the monitoring screen when the monitor is turned on. When the
monitoring screen is displayed, press the menu button once to change to the setup screen.
When the setup screen is displayed, press menu button once to change to the trend graphs
screen. When the trend graphs screen is displayed, press menu button once to return to the
monitoring screen. The menu button repeatedly cycles between the three screen modes in
the above sequence.
4.3 Monitoring Screen Display and Operation
The monitoring screen has two forms, parameter monitoring screen and
waveform/parameter monitoring screen.
4.3.1 Parameter Screen Display
The LCD displays the parameter monitoring screen. Parameter screen displays
measurements of the parameters. The monitor can identify which sensor is connected and
then display the appropriate parameter screen automatically. There are four various
parameter screens altogether.
