AC and Battery Operation
1-8
The following is a list of AC and battery operating instructions:
• A fully charged battery (without AC power) will operate continuously for about 3
hours. A weak or faulty battery will reduce this time.
• The battery status may be identified from the upper screen. means no bat-
tery or bad battery. indicates the battery needs to be charged. Once the
is displayed, the cardiograph can operate continuously for 20 minutes
before it automatically is turned off. If the symbol flashes, the cardiograph
will automatically be turned off in 2 minutes. A weak or faulty battery will reduce
this time.
• The M2662A cardiograph has a battery-saving feature: it will turn itself off after
10 minutes of instrument inactivity. This prevents the cardiograph from being
accidentally left on for extended periods of time.
• A fully depleted battery will charge to full capacity in 4 hours. The power indica-
tor becomes green when the battery is full.
The battery-saving feature is not activated if all the limb electrodes are connected to
a patient, or if the cardiograph is plugged into AC power via the AC/DC Power
Adapter.
When plugged into AC power via the AC/DC Power Adapter, the cardiograph
continues to charge the battery in low current after the quick charge is over. To
prevent overcharge, it is recommended that the cardiograph not be connected to AC
power for more than a week. This will prolong battery life.
The AC/DC Power Adapter supplied with this cardiograph is an integral part
of the cardiograph’s safety features. Using any other AC/DC Power Adapter
may compromise the cardiograph’s safety as well as performance.
