Mindray BeneVision N1 User Manual

BeneVision N1 Patient Monitor Operator’s Manual A - 9
■ The delay for monitor-related settings configured at the CMS to be effective: ≤ 2 seconds.
■ The total delay of data transmission from one monitor to the other: ≤ 2 seconds.
■ The delay for the monitor to reset alarms of another to be effective: ≤ 2 seconds.
A.13.2.3 Wi-Fi Network Stability
The ratio of the communication data loss on the CMS from any monitor does not exceed 0.1% over a 24-hour
period (12 of the 16 monitors connected to the network roam for 30 times).
Testing conditions are as follows:
■ Number of the monitors supported by a single AP: ≤ 16.
■ Each monitor can communicate with the CMS.
■ Two monitors are used to view other monitors.
■ Only one monitor can transmit history data.
■ The weakest strength of the AP signal where the monitor is located cannot be less than -65 dBm.
A.13.2.4 Line of Sight Distance
The line of sight distance between the monitor and the AP is no less than 50 meters.
A.14 Measurement Specifications
The adjustable range of alarm limits is the same with the measurement range of signals unless otherwise
specified.
