1. INTRODUCTION
This Service Manual has been prepared for the maintenance and service of any of
the various models of the Omicrom FT Portable Vital Signs Monitor.
The technical qualified personnel must read carefully and thoroughly this
manual before performing any disassembly or maintenance procedure
The family of Omicrom FT monitors have several models that monitors different
physiological signs. All models have a common base that contains a metallic
chassis, an external plastic enclosure and two common boards that provide power
supply and communications for the rest of boards. Each model includes different
measurement boards as a function of the measured parameters. An essential
documentation to use this Service Manual is the Operation Manual of the monitor,
that provides complementary information.

1.1. Quality, Reliability and Safety.
This equipment has been designed with an special emphasis on those aspects
related with quality, reliability and safety, but RGB MEDICAL DEVICES will accept
responsability for these aspects when the following conditions are met:
a)Electrical installations in which the monitor is to be used must
comply with all regulations specified by the country in which the
monitor is being used.
b)The monitor is used in accordance with the instructions for use
provided by RGB MEDICAL DEVICES.
c)All maintenance, modification or repairment operations are
carried out by qualified personnel authorised by RGB MEDICAL
DEVICES.
d)Equipment installation must be carried out in accordance with
local requirements regarding responsibility and warranty.

1.2. General Precautions.
Read the following precautions thoroughly before performing any of the
disassembly procedures, because serious damage to the personnel or the
equipment can result if the precautions are not strictly followed.
All service operations must be carried out by qualified personnel. Besides, these
operations can only be performed by authorised personnel by RGB MEDICAL
DEVICES.
Before cleaning the equipment, always switch it off and disconnect it from the AC
power supply. Do not allow any liquid to enter the equipment case. Do not pour
liquid on the equipment while cleaning. Never use any abrasive material to make
the cleaning. Keep plugs and connectors meticulously clean and dry.
Do not expose the equipment to high humidity or heat.
Before starting with the disassembly procedure, the monitor must be turned off. It
is necessary to remove the power cable and all signal cables.
The front panel of the monitor is vulnerable to scratching, so a rough handling can
damage it.
When the monitor is reconnected and the power turned on without the plastic
covers, it is necessary to be careful in order to avoid exposure to high voltage. In
this case, do not power up the chassis on a conductive surface such as a bare
metal table. Place the chassis on a non-conductive material.
In order to avoid an electrostatic discharge, it is necessary to use adequate
protective means, such as antistatic surfaces and earthing means for technical
personnel. In case of handling spare parts sensitive to discharges, handle these
parts into their original package.
Normally, the measurement boards have a floating input section which is isolated
from the remainder of the board. Never handle this section of the board, because
the oil, dirt or dust deposited on these sections can cause leakage paths which
can degrade floating circuit isolation and patient safety.
During the disassembly procedure, be sure to keep all screws, nuts, plastic
spacers and other accessories for the posterior assembly of the monitor.

2. SERVICE INFORMATION
This chapter include several sections where different type of information for
servicing the Omicrom FT monitors is included.
2.1. Monitor and accessories cleaning.
The Omicrom FT monitor and accessories must be kept clean on a routine basis,
in accordance to the instructions provided here. To clean the monitor or their
accessories it is necessary to disconnect the monitor from the AC Power and the
different accessories from the monitor. After cleaning of the different parts of the
equipment , always allow them dry thoroughly before use.
The outside of the monitor may be wiped clean with a cloth slightly dampened with
mild detergent or normal hospital bactericides. Liquid must not be poured inside
the equipment. It must not be cleaned with isopropyl alcohol or other dissolvents.
Do not use abrasive agents. Avoid liquid entering inside the NIBP connector.
As a general rule, do not immerse the different cables and probes into water or
any other liquid. Besides, the continued flexing of cables and wires during the use
of the monitor or during the cleaning procedure could break the internal wires
and, as a consequence, produce the failure of the monitor.
A very important aspect that must be considered is the cleaning procedure of the
cuffs and hoses supplied with the unit. Care must be taken not to immerse these
elements in any kind of liquid to avoid that the liquid enters them at any time. If
this happens accidentally, then it may be dried by passing air through the cuff.
The cuff can be cleaned by hand washing in warm soapy water.
Both the ECG cable and the electrode leads may be cleaned and disinfected by
wiping with a 10% solution of household bleach or any other similar commercial
product. Do not use alcohol, since it will attack the protective plastic cover of the
cables causing them to undergo a premature erosion.
For the cleaning of sensors or cables, hold the sensor in one hand at the tip and
wipe the sensor and cable towards the plug end. If excessive pressure is used,
the covering will be stratched, which may break the internal wires and destroy the
probe.
Do not boil or autoclave the monitor, the sensor or the cables, because it can be
destroyed.

Information by display:
The display can monitor the waveforms of ECG, NIBP,
SpO2, invasive pressure and respiration. The display
shows the numeric value of each measured parameter.
It shows all relevant information about each monitored
sign.
Heart Rate Measurement:
From each pulsatile signal, the system detects the
presence of a pulse and provides an acoustic and
visual indication. The source of the heart rate showed
is selected dynamically as a function of the active signs
(if it is not in an alarm situation) according to the
following priority criteria:
1) ECG
2) PRES1
3) PRES2
4) SpO2
5) NIBP
Alarm detection system:
For each vital sign monitored there is an independent
alarm detection system, that detects several alarm
conditions.
The presence of an alarm situation is indicated by
visual and acoustic means.
It is possible to disable the warnings for all signals at
the same time.
It is possible to disable the alarms of each parameter in
an independent way:
It is possible to select the patient alarm levels for each
parameter. These levels can be stored to be used the
next time the monitor is turned on.
The procedural alarms that can be detected have been
specified in previous sections.
Trends Storage:All parameters measured are stored periodically. The
time period between consecutive storage is selectable
by the user (options: 1, 2, 3, 5, 7, 10 and 15 minutes).
According to the selected time period, the storage
capacity varies between a minimum of 5 hours and a
maximum of 72 hours.

2.3. Verification routines.
In this section it is explained the verification procedures that must be followed to
ensure that the Omicrom FT monitor is performing well.
Any failure detected during the tests must be located and repaired. After this
repairment, the monitor must be checked again completely before using it.
2.3.1. Daily verification routine.
Daily or each time the monitor is used, the operator must review the next points:
1. To inspect the monitor and the accessories and, if signs of damaged are
detected, replace or not use the damaged items.
2. To clean the monitor and their accessories according the instructions
given in section 2.1.
3. To inspect the AC power cord and, if signs of damage are detected,
replace it with an original RGB part replacement.
4. To check the battery status. Power up the monitor from its internal
battery and check the level of charge at the indicator placed at the
bottom right part of the display. If the charge level is too low or if the
‘Battery’ LED is flashing, connect the monitor to the mains supply and
switch on the rear panel mains power switch. Leave the monitor
charging until the charge level reaches the maximum.
5. To check the monitor operation. The basic points to check are: graphical
presentation by the display, adjustment of the parameters measured,
selection of the configuration options and adjustment of patient alarm
levels for each parameter. After checking these points, return all
adjustments to the desired settings.
If any failure is detected during this daily verification, contact with qualified
technical personnel authorized by RGB MEDICAL DEVICES for servicing the
monitors.
2.3.2. Periodical verification routine.
This sections describes the verification routine that must be performed each six
months by a qualified technician. Previously it must be done the daily verification
routine describe at the previous section.
In order to carry out this verification, it is necessary to use the next auxiliary
equipments:
• BioTek Simulator Model LionHeart 3 or equivalent.
• Pressure manometer.
In this section it is described the verification associated with each signal. Only it is
necessary to carry out those verifications, according the Omicrom FT model (so
each model monitors several signals). To verify each signal only it is necessary to
activate the signal at the monitor.
