signal degradation. Always refer to the ANSI/AAMI Standard EC12-1991 for
safety, performance, and labeling requirements for the disposable electrodes,
and guidelines for reliable patient connections.

2. Any body hair around the electrode site must be removed by dry shaving.
The electrode site must be thoroughly cleaned to remove surface skin oil and
dirt. Use a gauze pad moistened with alcohol to properly clean the area.
Gauze should be used rather than alcohol prep pads because of its superior
abrasive quality.

Gauze should be used rather than alcohol prep pads because of its superior
abrasive quality.
3. The center of the electrode site where the pad of the electrode will make
contact with the skin should be wiped 3 or 4 times with a small piece of extra
fine sandpaper or similar abrasive material to remove the dead superficial
layer of skin. This will significantly improve the electrical contact between the
skin surface and the electrode to provide a quality signal.

4. Finally, proper patient hookup of all channels/leads should be thoroughly
tested by using the built in hook-up review feature to verify that the
appropriate amplitude signal is being obtained from each channel/lead
without noise or artifacts.

Typical Electrode Placement
The Model 950-12LR-HHC has two major modes of operation:
1. Standard 12-Lead mode
2. Optional 3-channel mode.
The cable used on the unit determines the device mode of operation. Changing
the mode requires insertion of the appropriate cable. The cable options are:
the mode requires insertion of the appropriate cable. The cable options are:
•
10-wire cable for 12-lead recordings
•
7-wire cable for 1, 2 or 3-channel recordings
The standard patient electrode connections to this device use a 12-Lead/10-Wire
cable that conforms to the standard AHA electrode color code system as
specified in ANSI/AAMI EC11:1991/(R)2001. See Figure 1- Hookup for 12-
Lead/10-Wire.
For special applications an optional cable is available to allow viewing and
recording of 1, 2, or 3 individual channels. This is a seven lead cable that uses
the standard AHA electrode color code system as specified in ANSI/AAMI
EC13:2007. See Figure 2 - Hookup for 3-Channel 7-Wire.
