The following alarm indications are displayed in reverse video. Alarm indications appear on the center of the screen
and flash once per second. ALARMS PAUSE message (PAUSE) is also displayed on the center of the screen and is
displayed in normal video and red text.
ALARMS OFF: The audible and visual alarms have been turned off.
LEAD OFF: A lead has become disconnected. This alarm cannot be reset with the
ALARM PAUSE key.
HR HIGH: The high heart rate limit has been exceeded for four seconds.
HR LOW: The low heart rate limit has been exceeded for four seconds.
ASYSTOLE: The interval between heartbeats has exceeded six seconds.
PAUSE: The alarms are paused for 120 seconds.
WARNING: The monitor always powers on with the ALARMS set to OFF.
Rear Panel:
The following are located on the rear panel.
POWER INPUT: A receptacle for a standard ac power cord.
When the monitor is connected to another piece of equipment, always make sure that each piece of connected
equipment has its own separate ground connection.
Do not attempt to connect cables to these connectors without contacting your Biomedical Engineering Department.
This is to ensure the connection complies with leakage current requirements of one of the following applicable
standards: UL2601-1, CAN/CSA C22.2 No 601.1-M90, IEC 60601-2-25, and CE-MDD 93/42/EEC. The maximum
non-destructive voltage that may be applied to these connectors is 5V.
SYNCHRONIZED OUTPUT: A BNC type connector for the output of the synch pulse indicating the timing of the
peak of the R-wave. Limit to 100Hz bandwidth.
PEQ GROUND: Potential Equalization - A ground connection that can be used to ensure that no potential
differences can develop between this equipment and other electrical equipment.
FUSE: Replace only with the same type and rating of fuse as indicated on the fuse rating label T.5A 250V (Metric
5x20mm).
ECG X1000 and SYNCHRONIZED OUTPUT: This is a ¼ stereo phone jack with an ECG analog waveform
output on the tip, synch output on the ring, and common on the sleeve. Limit to 100Hz bandwidth.
AUXILIARY: A digital interface for device communication. This auxiliary output provides 5V and -8Vwith a
maximum current of 20mA.
SERIAL NUMBER LABEL: The serial number label indicates the model number and a unique serial number for
the monitor. The date of manufacture is encoded in the first 4 digits of the serial number using the YYMM format.
LINE VOLTAGE SELECTOR: Switch to select the input voltage range of the device (100 to 230V~, 47 to 63
Hz.).
