&KHFNLQJWKH9ROWDJH6HWWLQJ
Your cardiograph can be set to operate at nominal line voltages of 115
or 230 Volts (See NOTE ). The line voltage was set at the factory to the
setting for your area. However, it is a good idea to check this setting.
Refer to Figure A-1 for the physical location of the voltage select
switch. To check the voltage setting, perform the following steps.
1. Locate the voltage select switch on the back of the cardiograph. See
Figure A-1.
2. Verify that the correct voltage is visible on the voltage select
switch. If the voltage setting is incorrect, slide the voltage switch so
the correct voltage is visible. The cardiograph operates with any
line frequency from 50 to 60 Hz.
3. Remove and discard the label that covers the AC power receptable.
See for the location of the AC power receptable. The purpose of
the label is to remind you to check the setting of the voltage select
switch.
