(such as autoclaving). Do not use E-beam or gamma radiation sterilization.
Do not use solvent or abrasive cleaners on either the unit or cable assemblies.
Do not, under any circumstances, immerse the unit or cable assemblies in liquid.
Operating the device without the correctly rated fuse, or with defective cables,
constitutes a danger to life. Therefore:
– Do not operate the unit if the earth connection is suspect or if the mains lead is
damaged or suspected of being damaged.
– Damaged cable connections and connectors must be replaced immediately.
– The electrical safety devices, such as fuses, must not be altered.
– Ruptured fuses must only be replaced with the same type and rating as the
original.

the following:
– Ergometer (analogue or digital) for exercise testing
– External monitor
– Network cable
– External printer
4.1.3 Potential equalization
The potential equalization stud at the rear of the unit is used to equalize the ground
potential of the CP300 to that of all mains powered equipment in the vicinity. Use the
hospital or building common ground. A yellow/green ground cable is supplied as an
option.
Danger of electrical shock. Do not operate the unit if the earth connection is
suspect or if the mains lead is damaged or suspected of being damaged.
To avoid possible interference from the ergometer when carrying out an exercise test,
it is recommended that both the CP300 and the ergometer are connected to the same
common ground.
To prevent the possibility of leakage current when an external printer, external
monitor, or ergo device is connected, always ensure that th e mains lead (with
earth grounding connection), and / or the potential equalization, is attached to the

Service handbook CP300 Glide Point Controller Operation 4.2
4.2 Glide Point Controller Operation
Only light pressure is required to move the cursor and select items by tapping with the
finger. The glide point controller will not work correctly if excessive pressure is used.
To select any menu item or to confirm a setting, select a function etc., the procedure
is the same.
Selecting an Icon
1. Move finger lightly over the glide point controller to position the cursor (arrow) on
the icon that you wish to select.
2. Lightly `double tap` (same as a double clic k with a mouse) the glide point
controller to select.
Pull down menu item
1. Move finger over the glide point controller - the cursor (arrow) on the screen
moves.
2. Position the cursor on the horizontal menu bar and lightly tap the glide point
controller - further menu items are displayed and can be selected in the same
way.
Right Click Function
The lighter area in the top right corner of the glide pad has the same function as the
`right` button on a conventional mouse.
4.2.1 Connecting a Mouse or Trackball Device
The CP300 can work with an external point and control device. When a mouse or
trackball etc. is connected (to the PS-2 connector on the back panel), the glide point
controller operation is disabled.

Important
The device is delivered without printing paper installed. The thermo-paper is sensitive
to heat, humidity and chemical vapors. The following points apply to both storage, and
when archiving the results.
• Before use, keep the paper in its original cardboard cover. Do not remove the card-
board cover until the paper is to be used.
• Store in a cool, dark and dry area.
• Do not store near chemicals e.g. sterilization liquids.
• In particular do not store in a plastic cover.
• Certain glues can react with the paper - do not attach the printout onto a mounting
sheet with glue.
Welch Allyn can only guarantee perfect printouts when CP300 original chart paper or
chart paper of the same quality is used.

5 Physical and Functional
Overview
5.1 Physical Overview
The CP300 unit is enclosed in a two part, medical standard, molded plastic case.
The top part contains the keyboard and the LCD screen with the base section
containing all the electronics of the unit, the RS-232 interface, the thermal printer, the
paper tray, the battery and mains transformer.
The electronics of the unit are contained on a single double sided printed circuit board,
the main board (MK 17-1). This board is secured on spacers molded in the base
section.
The battery is secured in position in a molded recess accessed from the bottom of the
units, and the mains transformer is secured on spacers above the printed circuit
board.
The thermal printer is mounted on spacers mold ed to the base and the paper tray
motor mounted in a similar way.
Exploded views of the unit are given in the Construction Drawings section at the end
of this book (see page 75).
5.2 Functional Overview
The CP300 has a PC architecture, including standard expansions like a network
connection and USB ports, etc. The electronics of the CP300 including the power
supply, is contained on a single Main Board (MK 17-1), which contains a ' piggy back'
PC single board controller. The electronics of the CP300 are EMC shielded.
The ECG board provides isolated patient connection and initial processing of the ECG
signals.
The operating system in the CP300 is Windows® NT or XP. The user interface, all
settings, graphical presentations etc. are based on Windows®. The evaluation of the
ECG data, control of the printer and other functions are realised on the Welch Allyn
ECG processor card with its own 68331 microprocessor system. The systems
communicate with each other via dual port RAMs.
Interconnection and EMC drawings are given in the Construction Drawings section at
the end of this book (see page 78).

Every 12 months
a
a. The time interval for the electrical safety tests is a guideline and can vary according to local and country specific directives and according to unit use. For example when a unit is used intensively, safety checks should be carried out more often. When a unit is used
less intensively, the safety check period can be longer. In addition the safety test must be carried out in the following circumstances:
-If a unit is dropped, receives any large jolt or knock or is subject to severe vibration, etc.
-If a unit has been subject to strong radiation or electrical shock, etc.
-When a unit has been repaired or serviced that requires the case to be opened.
-Additionally, a safety test can be carried out at any time if the unit isolation is suspected of being inadequate.
• Electrical safety tests according to either:
– IEC 60601-1, (see page 37), or
– EN 62353:2005, or
– Local directives
b
b. The two directives detailed here are standard specifications for reference. Local and country directives for safety testing of medical
devices must be adhered to and take precedence.
