3.3.1 Turning the Power On and Off
When the power is off, press the POWER key to turn the power on.
Press the POWER key again to turn the power off.
Pressing the POWER key after the power is turned off does not turn
the power on for approximately two seconds.
When the power is on, check that the instrument operates normally.
Turn the power off before disconnecting the AC adapter from the power supply.
Remove the plug of the AC adapter from the instrument when running the
instrument on batteries.
3.3.2 Auto Power Off
When running the instrument on batteries, the LCD screen ashes (alarm)
if approximately 9 minutes 30 seconds elapse without a key being pressed.
If no operation is performed within approximately 30 seconds after that,
the power turns off automatically.
(The auto power off function is set to ON at the time of shipment.)
To continue using the instrument after the screen begins ashing,
press any key other than the POWER key so that the screen stops
ashing and lights.
Tip
If the AC adapter is in use or the CPH range is selected for pulse measurement,
the instrument is not turned off automatically regardless of the auto power off setting.
For details on canceling the auto power off function, refer to "7. Setting Mode."
