1. Introduction
1.1 Purpose and Scope of Document
The sheet 190 is the leading specification and is the response of development to the HAV as requested by
Product Management. Whenever the specification cannot be met, Product Management is to be informed
as early as possible in order to make sure the marketing can respond in time.
This sheet 190 does not cover software specifications. Software is described in the URS documents
and in the version matrix owned by Product Management. Product Management is responsible for
maintaining, distributing and updating the version matrix.
Sheet 190 will be part of the Philips official documentation from stage 2 onwards. All changes to sheet 190
have to be submitted via Change Proposals. Changes have to be marked in bold and/ or colours in the
document for easy recognition in at least the update right after the change. Deletion of text is done by
strike through in order to make changes obvious in at least the update after the change took place.
12NC and EAN codes will follow the overview sent out by product planning group HK.

4.1.1 Shock Sensitivity
Refer to Quality plan for the details of the test discs and testing method.
Requirement:
No muting, plop sounds, picture freeze/jerk or audible/visible interference when impacting with force of -
In the X and Y directions: F 3g / 3ms, V = 0.06m/s
In the Z direction: F 2g / 3ms, V = 0.04m/s
Where g = acceleration due to gravity.
4.1.2 Thermal Performance
Refer to Quality plan for the details of the testing method.
Requirements:
1. Set should function normally
2. Temperature rise of accessible parts such as metallic enclosures (casing) shall not exceed 40˚C
above the ambient temperature.
3. Temperature rise of PCB prints shall not exceed 85˚C
4. Temperature readings of all mechanical / electrical components and modules shall not exceed their
specification limits. The calculated junction temperature of semiconductors shall also not exceed
spec limits.
4.1.3 Noise Specifications

GB WARNING
All ICs and many other semi-conductors are
susceptible to electrostatic discharges (ESD).
Careless handling during repair can reduce life
drastically.
When repairing, make sure that you are
connected with the same potential as the mass
of the set via a wrist wrap with resistance.
Keep components and tools also at this
potential.
