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 220240V (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 builtin 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).

Introduction The Welch Allyn Schiller AT-1 is a 3-channel ECG recorder with the following features: °
Low weight and compact dimensions.
°
Built-in rechargeable battery for mains-independent use.
°
Simple one key operation.
°
Automatic or manual recording modes.
°
Selectable printing formats with integrated quality thermal printer.
°
ECG memory for easy copying.
°
Choice of 8 languages for printing.
The unit receives and processes all ECG signals simultaneously and continuously records the data in a circular 10 second memory. If there is any disturbance (i.e. loose electrode or end of paper), an audible alarm is given and the corresponding indicator lamp flashes, for example
As long as the disturbance remains, no ECG can be stored. As soon as the defect is eliminated, storage starts.

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 righthand side of the unit and secured with the two screws. The AT-1 is CF rated. The patient connection is fully isolated and defibrillation protected. Protection against defibrillation voltage is however only ensured, if the original SCHILLER patient cable (Part-no. 2.400070 / USA: 2.400071) 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.
