Power Supply The mains connection is on the rear of the unit. The power supply voltage is set by the factory for100-115V(nom. 110V) or 220-240V (nom. 230V) working. The setting is indicated by the indented metal strip on the fuse panel. Contact your dealer if the voltage needs to be changed. The mains indicator lamp on the keyboard is always lit when the unit is connected to the mains supply. The unit can either be operated from the mains supply or from the built-in rechargeable battery. The power source is indicted on the top line of the LCD. Changing a Mains Fuse If it is necessary to change a fuse, always replace with the correct rating i.e 2x200mAT for 230V, or 2x315mAT for 110V . To change a fuse press the two retaining lugs on side of the fuse panel (situated below the mains connector on the back panel. Remove the fuse panel and replace the fuse(s). Click back the fuse panel.

Patient Cable Connections The accessory kit of the electrocardiograph includes a 10-lead patient cable. This cable is plugged into the patient cable socket on the right-hand side of the unit and secured with the two screws. The AT-2plus is CF rated. The patient connection is fully isolated and defibrillation protected. Protection against defibrillation voltage is however only ensured, if the original WELCH ALLYN SCHILLER patient cable (Part-no. 80130-0000) is used. Make sure that during ECG recording neither the patient nor the conducting parts of the patient connection or the electrodes (including the neutral electrode) come into contact with other persons or conducting objects (even if these are earthed). The quality of the ECG is dependent on the preparation and the resistance between the skin and the electrode. To ensure a good quality ECG and minimise the skin/electrode resistance, remember the following points:

1.

Ensure that the patient is warm and relaxed.

2.

Shave electrode area before cleaning.

3.

Thoroughly clean the area with alcohol.

4.

Place the C4 electrode first - in the fifth intercostal space on midclavicular line. Then place:

•

C1 in fourth intercostal space at the right sternal border

•

C2 in fourth intercostal space at the left sternal border

•

C3 between, and equidistant to, C4 and C2

•

C6 on left midaxillary line on the same level as C4

•

C5 between, and equidistant to, C4 and C6

The electrode placements shown on the following page are labelled with the colors according to IEC requirements. The equivalent AHA colors are given on the table opposite.

Location & Power

Power Indication

Location Do not keep or operate the apparatus in a wet, moist, or dusty environment. Also, avoid exposure to direct sunlight or heat from other sources. Do not allow the unit to come into contact with acidic vapours or liquids, as such contact may cause irreparable damage. The unit should not be placed near X-ray or diathermy units, large transformers or motors. The unit must be placed on a flat surface and must not be operated in areas where there is any danger of explosion.

Power Supply The mains connection is on the rear of the unit. The mains indicator lamp on the keyboard is always lit when the unit is connected to the mains supply. The unit can either be operated from the mains supply or from the built-in rechargeable battery. The power source is indicted on the top line of the LCD.

HR: 76/min

R L F C1 C2 C3 C4 C5 C6

When mains is connected a mains symbol is displayed (as shown above). When the unit is running on battery power a battery symbol is displayed:

When battery capacity is limited, the battery symbol flashes on and off. To recharge the battery, connect the apparatus to the mains supply by means of the supplied power cable. A totally discharged battery needs less than 15 hours to be fully recharged (60% in less than 3 hours, 90% in less than 7 hours). A fully charged battery gives approximately 4 hours of normal use. The unit can remain connected to the mains supply without any danger of damage to either the battery or the unit.

Switching On and Off The SCHILLER AT-2plus is switched on with the green ON key

ON and off by means of the red OFF key

Potential Equalisation If the AT-2plus is used in conjunction with other patient connected equipment, we recommend that the potential equalisation stud (on the rear of the unit) is connected to the hospital/ building common ground using the yellow/green earth cable. When working from an emergency vehicle, the vehicle common ground can be used.

OFF

The unit is automatically switched off after 5 minutes (30 seconds if battery capacity is limited) if no key is pressed and the patient cable is not connected.
