Warnings
Graphical Symbols
This lightning flash with arrow symbol, within an equilateral is intended to alert the user of the presence of un-
insulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk
of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert the user of the presence of
important operating and maintenance (servicing) instructions in the literature accompanying the
appliance.
This service manual contains various CAUTIONS and WARNINGS indicated by triangular warning
symbols, which should be read and understood in order to minimize the risk of personal injury to

PDI could not possibly know, evaluate, and advise the service industry of all conceivable methods in which
service might be done or of the possible hazardous consequences of each method. Accordingly, a
technician who uses a service procedure or tool which is not recommended by PDI must first satisfy
themselves thoroughly that neither their safety nor the safe operation of the equipment will be compromised
by the service method selected.

Disinfecting and Cleaning
The P10LCDD should be disinfected before performing any service. The following procedure is only a
recommendation. Your hospital or company may have a different procedure to follow.
CAUTION – Before using any cleaning or disinfecting
agent on the P10LCDD, perform a spot check by wetting
a small area of the cabinet. Verify the agent does not
discolor or deteriorate the cabinet.
Disinfecting
1. The P10LCDD has been designed to withstand up to a 25% chlorine based disinfectant.
Many alcohol and ammonia based disinfectants have also been tested with success.
However, before using any cleaner or disinfectant, spot check a small area on the
cabinet.
2. Apply the cleaner or disinfectant per its recommended instructions.
NOTE: Most disinfectants require a waiting time following application and prior to wipe-down.
Cleaning
Stubborn ink and other scratch type marks may prove difficult to remove. A dilute solution of Isopropyl
alcohol will generally work when all else fails. However, full strength Isopropyl will remove the cabinet’s
paint. Use with caution!

Before handling the main board be sure that you have taken precautions to protect it and other the
parts from Electrostatic Discharge.
There are 5 connectors on the main board that must be detached before it is removed from the chassis. They are
the backlight, keypad, LCD panel, USB cable, and coax cable connectors. (Picture 5D) (See main circuit board
layout and interconnections diagram on page 13) Use a 7/16-inch wrench to remove the RF connector. A small, flat
screwdriver can be used to assist in the removal of the other connectors. There are locking mechanisms on the
keypad and LCD connectors. These need to be pulled out before the flex cables can be disengaged.
