4.4.3 Button Operation
The four multifunction buttons, Left arrow/Contrast, Right arrow/Waveform, Up
arrow/Backlight and Down arrow/Mute, act as cursor keys on the system setup screen.
Left and Right Arrow Buttons
The cursor moves left when the left arrow is pressed and right when the right arrow is
pressed. The cursor is indicated by a small black square. It moves to the item which is going
to be set up and this item is highlighted.
Up arrow Button
Use the up arrow to increase the values of the alarm sound level or date and time to
increase their values using the up arrow. When the values reach their maximum, they return
to the minimum and start increasing again.
With the cursor on the alarm on/off positions, press the up button to toggle between ON
and OFF.
The Up arrow button is inactive when the cursor is on the DATA OUT and STORAGE items.
Down arrow Button
Use the down arrow to decrease the values of the alarm limit values, alarm sound level or date
and time. When the values reach their minimum, they return to the maximum and start
decreasing again.
With the cursor on the alarm on/off positions, press the up button to toggle between ON and
OFF.
When the Down arrow button is pressed with the cursor on the DATA OUT or STORAGE items,
the relevant function is executed. WAIT is displayed instead of READY or CLEAR because the
data process takes a short. All buttons are invalid during these processes. WAIT will be
replaced by READY or CLEAR when the process is finished.
NOTE
•
Incorrectly set time and date interrupts the continuity of the trend time. The date or
time should only be adjusted when it is incorrect and should be done immediately after
the monitor is powered on.
•
Alarm limits setup is very important when monitoring. Avoid setting the upper limits
too high or the lower limits too low. For example, the PR upper alarm limit should not
be more than 20 bpm higher than the patient’s actual PR.
4.5 Trend Waveform Screen Display and Operation
The monitor saves parameter measurements every 2 seconds. The storage area can store 36
hours trend data and the new data will overwrite the oldest data automatically after 36
hours. The saved data will never be lost even if the monitor is powered off. It can be viewed
on the trend screen.
