SAFETY INFORMATION
This manual contains safety information which you as the user must follow to ensure safe operation of the Monitor/Recorder
unit. Refer to the appropriate manual for safety information on the specific monitor used with your Recorder. WARNING
information is intended to protect the patient and the operator, and CAUTION information is intended to protect the instru-
ment. The following general safety precautions, which do not appear elsewhere in this publication, must be applied during all
phases of operation and maintenance.
WARNING I
UseOnly With Tektronix Model 408,412,413, or 414 Monitor
Do not operate this Recorder in conjunction with any monitor other than those for which it wasspecifically designed (the
Tektronix Model 408,412,413, or 414 Monitors). To do so could result in unsafe operation of the Monitor/Recorder unit.
Only a Tektronix Field Service Center or other qualified service personnel should mate the Recorder to the Monitor unit.
Do Not Operate Monitor/Recorder in an ExplosiveAtmosphere
Do not operate the Monitor/Recorder unit in the presence of flammable gasesor anesthetics. Explosion can result from
operation in such an environment. Safety document NFPA 56A, Standard for the Useof Inhalation Anesthetics, paragraphs
24114(c) and 24032, states that with the appropriate precautions, portable electronic equipment may safely be operated at
five feet (or more) above the floor in anesthetic locations.
UseAC Outlet with Protective-Ground Contact
The Monitor/Recorder unit is compatible with isolated power systems as used in operating rooms. In non-isolated power
systems, this Monitor/Recorder unit is intended to be operated from a single-phase,earth-referenced power source having one
current-carrying conductor (the neutral or grounded conductor) near earth potential. Operation from power sources where
both current-carrying conductors are live with respect to earth (such asphase-to-phase on a three-wire system) is not recom-
mended, since only the line (or ungrounded) conductor has over-current (fuse) protection within the unit.
The unit has a three-wire (18-gauge,SJT grade) power cord and is normally supplied with a three-terminal polarized plug
(Hospital Grade) for connection to the power source and protective ground. The ground (earth) terminal of the plug is
directly connected to the frame of the Monitor/Recorder unit. For electric-shock protection, insert this plug only in a mating
'Hospital Grade'power outlet with aprotective-ground contact. Do not defeat the grounding connection. Any interruption of
the grounding connection can create an electric-shock hazard.
Inspect the power cord periodically for fraying or other damage. Do not operate the Monitor/Recorder unit from an ac power
source if the power cord or plug is damaged.
UseOnly Safe Methods of Interconnection
To ensure protection against electric shock from the Monitor/Recorder cabinet whenever auxiliary, line-operated equipment
is electrically connected to the unit, the Monitor/Recorder unit must be properly grounded. When the monitor is connected
to other line-operated equipment, battery operation should be avoided. If it cannot be avoided, the unit must be grounded
using the terminal provided on the rearpanel of the monitor. It is extremely important that equipment interconnections are
made in accordance with NFPA 768-T, Tentative Standard for the Safe Use of Electricitv in Patient CareAreas of Health
CareFacilities, section 3038, 'Signal Transmission Between Appliances~
Do Not Remove Instrument Covers
High voltage ispresent inside the monitor. To avoid electric-shock hazard, operating personnel must not remove the protec-
tive instrument covers. Component replacement and internal adjustments must be made by qualified service personnel only.
Do Not Touch Writing Stylus
Do not touch the writing stylus during Recorder operation because the stylus becomes very hot and may cause burns.
iv @

400 (SN 8020000 & up)
~
Protect the Monitor/Recorder From Foreign Material
Do not insert any object (such as hand, tool, etc.), or allow any foreign material to fall into the opening in the front of the
Recorder, as this can cause damage to the electronic components of the unit.
Monitor Mounting Adapter
When a Monitor/Recorder is attached to a pole or other support, a plastic support block must be in place on the side of the
Recorder under the monitor mounting adapter. Thissupport block, attached to the Recorder at the time of manufacture,
provides proper mechanical alignment for the mounting adapter. The Monitor/Recorder mounting fixture design intends that
the monitor mounting adapter be used ONLY with the support block installed on the Recorder. See mounting instructions
in GeneralInformation Section.

GENE L INF
DESCRIPTION
The 400 Recorder is a strip chart recorder (direct writer)
which attaches directly to a Tektronix Patient Monitor.
Five versions of the 400 Recorder are available (Standard,
Option 1, Option 2, and Option 3) to match the capabilities
of the 408, 412, and 414 Series Patient Monitors, and
Option 4, to match the 413 Series Patient Monitors. Al-
though each model of Recorder is designed to complement
a particular monitor's capabilities, any Recorder model can
be used on any of the above series monitors with certain
feature limitations. To optimize feature matching, refer to
Figure 1-1 for the recommended Monitor/Recorder
combinations.
The chart Recorder produces permanent paper-strip copies
of monitored data. All Recorder models provide single-
channel waveform writing of selected patient parameters at
two selectable chart speeds. The Recorder display is always
one half the amplitude of the monitor display. In addition,
Section 1-400 (SN 8020000 & up)
TION
the Option 2, 3, and 4 Recorders also provide an alpha-
numeric printout, with every record cycle, of patient vital
signs and elapsed time. (This feature is effective only in
conjunction with the 413 & 414 Series Monitors.)
Record cycles of 14-second duration (or28-second duration
for the Option 3 Recorder) can be initiated manually or
automatically. The automatic record cycles can be initiated
at nominal 15-minute intervals and upon monitor alarm.
Waveform writing is accomplished by a thermal stylus (uses
no ink) on heat-sensitive paper. A stylus heat control is pro-
vided for adjustment of copy darkness.
Recorder-equipped monitors are single-unit portable instru-
ments, requiring no separate power or external interconnect
wiring. Recorders operate directly from the monitor's
internal battery pack and add only about 8 pounds to the
monitor package.

General Information-400 (SN B020000 & up)
SPECIFICATIONS
The electrical specifications in Table 1-1 apply when the following conditions are met: (1) The recorder must have been
mated to an appropriate Tektronix monitor (see Fig. 1-1), (2) the instrument must have been adjusted at an ambient temper-
ature between +20 and +30 degrees C (+68 and +86 degrees F), and (3) the instrument must be operating in an ambient
temperature between 0 and +50 degrees C (+32 and +122 degrees F).
NOTE
The recorder obtains its operating power from the monitor battery pack even when the monitor is
connected to the acpower line. Batteries presently used in monitors accept less than a complete
charge at ambient temperatures above +25 degrees C. Therefore, availablemonitor and recorder run
time is reduced in ambient temperatures above +25degrees C.

Record Sample Time
Blood Pressure (BPA)
28, ±2.8 seconds, or until printout com-
plete. Printout starts 14, ±1.4 seconds
after sample is initiated.
Prints out in millimeters of mercury
(mmHg). Accurate to ±5 mmHg of mon-
itor input. Pressure value settles to ±3
counts of final reading, 10 seconds after
a pressure change occurs.
Set at P182 on Run Control board.
Prints systolic, diastolic and mean
pressure values for Channel A and then
Channel A/V. Printout is eliminated if
pressure transducer is disconnected
from monitor. A minus sign is printed
for negative pressure values.
1 The pressure channel of single pressure 414 Monitors (414,414 GA, etc.) is always on, except in PULSE mode. When no pressure transducer
is connected to the monitor, the pressure channel "floats" causing the recorder to print invalid blood pressure values.

408/412/414 MONITOR/RECORDER ADAPTER KIT INSTALLATION
NOTE
It is intended that this kit be installed only by Tektronix Service personnel.
INTRODUCTION
To join a 400 Series Recorder to any Tektronix 408,412,
or 414 Monitor, the following items must be at hand:
1. A 408,412, or 414 Monitor.
2. A 400 Recorder.
3. An 016-0498-00 Adapter Kit, which contains sufficient
electrical and mechanical parts to connect any option re-
corder to a 408, 412, or 414 monitor. This kit is shipped
with all recorders except the Option 4.
4. A monitor battery pack manufactured subsequent to
summer 1976. These packs have heavy cell interconnects, a
fusing arrangement, and a special connector which provides
power to the recorder. If needed, this battery pack must be
ordered separately.
Battery-Pack Ordering Information
All monitors mated to alpha-numeric printing recorders
(Options 2, 3, 4) must have F-cell battery packs for satis-
factory operation. D-cell packs, although not recommended,
can be used in a monitor mated to Standard or Option 1
recorders. However the result is about 50% less operating
time. Select the appropriate battery pack from the list below.
To replace with Order Tektronix Part No.
D-cells D-cells 119-0441-01
D-cells F-cells 040-0710-01
F-cells F-cells 119-0443-01
F-cells D-cells Not recommended
Figure 1-8 shows a typical 408, 412, or Monitor/Recorder
installation. These steps summarize the installation
procedure.
1. A -01 battery pack is installed in the monitor (providing
it doesn't already have a battery pack, or its pack does not
have provision for recorder operation).
1-10
NOTE
If a new battery pack is to be installed, the re-
sistor which determines battery chargingcurrent
may need to be replaced. Instructions and the
proper resistor arepackaged with each new
battery pack.
2. A Manifold Board is installed in the monitor. This is the
interconnection point between various monitor models and
the recorder.
3. The necessary cables are connected from the monitor
internal circuitry to the Manifold Board.
4. A multi-conductor ribbon cable is connected between
the Manifold Board and the Recorder.
5. The monitor and recorder are joined mechanically and
tested.
INSTALLATION INSTRUCTIONS
A. Monitor Preparation
NOTE
Check off each step as you complete it.
1. Check contents of Adapter Kit. Check that you have all
the components before beginning. See Figure 1-9.
2. Obtain a Service Manual for your monitor. You will have
to refer to it later in these instructions.
3. Prepare Monitor.
a. Disconnect monitor from ac power source.
b. Remove top cover. Remove two screws on each side.
Lift up left side of cover, make sure it has cleared the
ECG LEAD CHECK terminals, and remove cover from
the monitor.
c. Remove bottom cover. Remove two screws on each
side and pull cover straight off.
d. Unplug the battery cable connector P711 from the
main board. You will be instructed to reconnect it in a
later step.

i~~l
Do not short cells. Nickel-cadmium cellsare
capable of delivering high currents which can
cause wire insulation to melt.
4. If necessary, replace battery pack with new one which
has been adapted for recorder use. See list of battery packs
in the introductory portion of these instructions. Do not
connect either the recorder or monitor battery connector
until instructed to do so.
@
~
Most of the monitor and recorder circuits can
be damagedby the dischargeof static electricity
into them. The damage may not become ap-
parent for several months. Before proceeding,
review and adhere to the Recommended Handl-
ing Rules on page 4-8.
5. Install white-violet wire (with violet connector) on main
board. See Figure 1-10 for 414 Monitors or Figure 1-11 for
408 and 412 Monitors.
