SE-12 Series Electrocardiograph User ManualOperation Preparations
The electrocardiograph can be powered by either the mains supply or the battery.
To turn on the Electrocardiograph:
♦ When operating on AC power
Make sure that the mains supply meets the requirements (refer to A1.4 Power Supply
Specifications) before power-on, and then press on the keyboard to turn on the unit. The
mains supply indicator () is lit, and the logo will be displayed on the LCD screen after
self-test.
If the battery is weak when the mains supply is used, it will be recharged automatically
at the same time. Both the mains supply indicator () and the battery recharging
indicator () will be lit.
♦ When operating on battery power
Press on the keyboard to turn on the unit, and then the battery indicator () will
be lit and the battery symbol will be displayed. The logo will be displayed on the LCD
screen after self-test.
Because of the consumption during the storage and transport course, the battery capacity
may not be full. If the symbol and the hint information Battery Weak are displayed,
which means the battery capacity is low, please recharge the battery first.
CAUTION
1. If the electrocardiograph is turned off because of low battery capacity or unexpected
power failure, the settings or the current ECG report may not be saved.
2. The electrocardiograph cannot print an ECG report when the battery is weak.
3. The use of electrocardiograph accessories (such as barcode reader) will deplete
battery power at a faster rate. The battery will require more frequent charging if
these accessories are used with the electrocardiograph.
