CP 20_______________________________________________________________________Section 2
To apply power to the electrocardiograph:
Plug the power cord into an AC wall outlet and into the back of the CP 20.
(Reference Figure 1-3). Unit powers on automatically and can not be turned off when AC is
connected (unit is in Stand by Mode).
If using battery power, press the power on/off button located on the lower right side of the
keyboard.
(Reference Figure 1-5).
Indicators on the keyboard will illuminate as follows:
The AC power indicator illuminates when unit is connected to mains (AC power).
The battery power indicator light illuminates when the battery is charging and will turn off once the battery
is fully charged.
The battery power indicator light flashes when battery is low (below 11.5 V).
The electrocardiograph should be connected to AC power for recharging whenever the unit is not in use.
TIP: Battery voltage is displayed at the bottom of Time/Date screen – see below.
NOTE: For typical usage, battery charging time should be approximately 8 hours or less.
CAUTION: When the battery charge is depleted to its lowest level (9.5V), the unit will
automatically power down. To recharge a battery from its lowest level, 30 hours of recharging
without operation will be necessary. Routinely discharging a battery to this level will severely
shorten the life of the battery.
To set the Time/Date and LCD contrast:
