Introduction
The recorder is an optional, standalone printer designed for use with the A1
patient monitor. The recorder communicates with the monitor using a null-
modem cable connected between each device's RS-232 connector.
The recorder contains an internal battery, which, when fully charged, will
operate the recorder for 3 hours (typical, at 25°C, producing fifteen 20-second
printouts per hour). The recorder can be connected to AC power using an
external power supply. The recorder uses the same type of power supply as
the A1 monitor, the PS-120V or PS-240V.
The recorder does not have an On/Off switch. The recorder can sense when it
has an established communication link with the monitor. At that time, the
green LINKED indicator on the front panel lights, indicating that the recorder
is ready for operation. See the recorder's User Guide for more information
regarding its operation.
To perform test and troubleshooting procedures and to understand the
principles of operation and circuit analysis sections of this manual, you must
know how to operate the monitor. Refer to the User Guide to understand the
various sensors, ECG lead, blood pressure cuffs, and temperature probes that
work with the monitor. Refer also to the user guide and individual directions
for use that accompany these accessories.
