SECTION 2

Applying Power

1. Plug the power cord into an AC wall outlet and into the back of the device. (Reference Figure 1-3.)

2. Press the power ON/OFF button located on the face panel of the device. (Reference Figure 1-5.)

When using AC power, the battery indicator is clear when charging and illuminates in white when fully charged.

When using battery power, the battery indicator illuminates in green with a 35% to 100% charge and in yellow with

a 20% to 35% charge. The battery indicator will turn to red when the battery charge is 20% or less.

The device should be connected to AC power for recharging when not in use.

TIP: Battery voltage is displayed at the bottom of the Time/Date screen.

NOTE: There are configurable features on the device that can be used to help prolong battery life (see

Section 4). Proper battery care and maintenance will also help prolong battery life.

CAUTION: The device can be operated on AC line voltage in the absence of a battery or in the

event of an otherwise fully depleted battery. When line voltage is removed the system immediately and

automatically continues on battery power. When the battery voltage is below 10.5V the device will

automatically power down. Once the battery voltage rises above 10.5V the device may be operated on

battery power. It may require up to 30 hours on AC line voltage to recharge the battery from its lowest

level. Routinely discharging a battery to the lowest level will severely shorten the life of the battery.

NOTE: When the On/Off button is depressed for longer than approximately 10 seconds, the

electrocardiograph will do a "hard reboot" and reset the internal clock to default date and time (1-1-2010)

and advise the user to “Set date/time.” When turned on, the user will need to re-enter the date and time.

This requirement may be bypassed if desired and an ECG can be acquired by selecting F6 (Exit) or

F5 (Save), but this ECG will have the date of 1-1-2010. With the next patient the electrocardiograph will

request the operator to enter the proper time and date again.

Low Battery Conditions

To prevent permanent damage to the internal lead-acid battery, the device will automatically power down when the

battery has been depleted to its lowest allowable level. When the device detects that the battery voltage has been

depleted to this level, it will display the messages “Battery Low – Charge Unit” for 10 seconds before shutting

down. Plugging in the AC cord during this time will cause the unit to return to the main acquisition screen.

If the device is in the ECG acquisition mode when the battery voltage is detected at its lowest allowable level, the

unit will display the message “Battery Low – Charge Unit”, but will not automatically shut down until the user exits

the ECG acquisition mode. This allows the user to complete an ECG already in progress.
