Enabling alarm annunciation
To conserve battery power, DISABLED is the default setting for the alarm event switch on
the Trend Download board. Change the switch setting to ENABLED only if you have
customized a cable and intend to connect the monitor to your local “nurse call” system.
•  If you are installing a new Trend Download board, you can change the switch setting
before completing the installation. See Before installing the Trend Download board.
•  If the Trend Download board is already installed, see After installing the Trend
Download board.
Before installing the Trend Download board
WARNING:  Internal electronic components are susceptible to damage by
electrostatic discharge. To avoid damage when disassembling the monitor,
observe the standard precautions and procedures for handling static-
sensitive components.
