However, four components are common to all system configurations. Base Station The base station is the interface between the customer at the menu sign and the headset worn by the operator. See Figure 1. Figure 1. Page 9 Model C1060 Programming Station System Description The programming station is used to program C960 and C1060 headsets to the same channel as the base station. Infrared light is used to transfer program data to the C1060 headset and a separate jack is provided for the C960 headset programming cable.Release the switch to listen.

Turn the headset OFF. 2. Turn the headset ON. The “ low battery tone” continues for two minutes after which the headset turns off automatically to prevent damage to the batteries.Remove protective backing from new pad and press it into place on the back of the battery housing. See Figure 12. Page 21 Model C1060 Maintenance Battery Charger Location The battery charger should be placed on a flat surface such as a desktop or table in a clean, dry environment. Batteries Care, Handling and Storage Avoid dropping batteries. Do not carry batteries in your pockets or leave them in hot, damp or dirty places. Page 22 Maintenance Model C1060 Disposing of Batteries To help protect the environment, C1060 rechargeable batteries which have reached the end of their useful life should be disposed of in accordance with local requirements. This helps ensure that a fully charged battery is always available. The headset automatically switches back to standby when the customer leaves the menu sign. To enable or disable the talk lock feature: 1. Turn the headset OFF. 2. Page 25 Model C1060 Special Instructions for System Manager The C1060 system is capable of operating on any one of eight different channels. You can correct these types of interference by changing the base station operating channel. See Figure 15. Figure 15. 2. Page 26 Special Instructions for System Manager Model C1060 Figure 17. 3.

Printed in U.S.A. ?3M 2001 February 70-0710-3648-0 Rev. Of the seven systems we evaluated, the number of categories often was not included in the description of the system or depended upon if the system was used to overlay existing DRGs or applied independently to individual case records. To ensure adaptability to existing hospital data and claims payment systems, the potential number of DRGs in any revised system that would include a severity measure was limited to no more than 999. Although increasing the number of patient classes generally improves accuracy in predicting resource consumption, it also increases the opportunity for manipulation of the system by shifting patients into classes with higher payments, as well as increasing the number of low-volume DRGs (i.e., those with fewer than 10 cases). Table 1 summarizes the extent to which the severity measures under consideration met the HCFA criteria previously described. Based on these criteria, we considered the RDRGs, AP-DRGs, and APR-DRGs to be the most promising refinements. Because these three systems all were originally based on the Medicare DRGs and use the same data sources and elements, they theoretically could be easily adapted and used for Medicare payment. In addition, the Medicare DRG system has been in place for more than 10 years, and its rationale and methodology are relatively well understood by hospitals. As a result, a new system based on the current DRGs would require less implementation time and costs for both hospitals and HCFA. With this in mind, these three classification systems are described later and are evaluated as possible severity systems for the Medicare population. Table 1 Ability of Severity Measurement System to Meet Health Care Financing Administration Criteria System Criteria AP-DRGs are New York All-Patient Diagnosis-Related Groups (DRGs). APACHE is Acute Physiological and Chronic Health Evaluation.
