RS232 Output: Allows for transmission of ECG to PC via the RS232 serial interface.
Battery Operation: Four hours monitoring with fully charged battery pack. Four hours of recharge
required for each hour of use.
Power Module: Compact convenient and independent unit with cable connection to AC outlet and
monitor rear panel. Recharges batteries and permits continuous AC operation.
Monitor automatically reverts to battery operation during AC power failure.
Size: 76mm x 50 mm x 152 mm
Weight: 0.7 kg
Heart Rate Limits: Upper and lower, heart rate alarms settings. Infinitely variable with audio alarms.
Power Supply: Separate mains pack to be provided this will have the ability to physically replace
the battery pack.
Separate units available, suitable for either
(a) 110VAC @ 60Hz, or
(b) 220VAC @ 50Hz, or
(c) 100VAX @ 50Hz.
Weight: 3.5kg including battery pack, without separate power/charger module.
Power Switch: Front panel push-button with ON indicator light.
Low Battery: ON indicator light flashes when 15 minutes of battery operating time remains.
Lead Selection: Full lead selection under micro control.
Size: Push-button selection of 0.5, 1.0, 2.0 c/mv gain and momentary 1 mv calibration
pulse.
Hold: Momentarily freezes trace on screen. Information on “hold” can be recorded from
delayed output jack.
Volume: Rear panel slide control varies volume of QRS bleeper. Range includes zero
volume.
Brightness: Rear panel slide control to optimise sweep displayed brightness according to
ambient lighting conditions.
Bandwidth: 30 Hz or screen.
AC Power Light: Amber Neon on C power module.
Packaging: The unit should be ergonomically efficient and packaged in ABC-type plastic. As this
is a low volume product a vacuum mode solution would be the most viable.
