PRODUCT SAFETY

IMPORTANT SAFETY NOTICEThis manual was prepared for use only by properly trained audiovisual servicetechnicians. When servicing this product, under no circumstances should theoriginal design be modified or altered without permission from ZenithElectronics Corporation. All components should be replaced only with typesidentical to those in the original circuit and their physical location, wiring, andlead dress must conform to original layout upon completion of repairs. If anyfuse (or Fusible Resistor) in this TV receiver is blown, replace it only with thefactory specified fuse type and rating. When replacing a high wattage resistor(Oxide Metal Film Resistor, over 1W), keep the resistor 10mm away from PCB.Always keep wires away from high voltage or high temperature parts.

Special components are also used to prevent shock and fire hazard.These components are indicated by the letter “x” included in their componentdesignators and are required to maintain safe performance. No deviations areallowed without prior approval by Zenith Electronics Corporation. Service workshould be performed only after you are thoroughly familiar with these safetychecks and servicing guidelines.

Circuit diagrams may occasionally differ from the actual circuit used.This way, implementation of the latest safety and performance improvementchanges into the set is not delayed until the new service literature is printed.

CAUTION: Do not attempt to modify this product in any way. Never perform customized installations without manufacturer’sapproval.Unauthorized modifications will not only void the warranty, but maylead to property damage or user injury.

GENERAL GUIDANCEAn lsolation Transformer should always be used during the servicingof a receiver whose chassis is not isolated from the AC power line. Use atransformer of adequate power rating to protect against personal injury fromelectrical shocks. It will also protect the receiver and its components from beingdamaged by accidental shorts of the circuitry that may be inadvertentlyintroduced during the service operation.

Before returning the receiver to the customer, always perform an AC leakagecurrent check on the exposed metallic parts of the cabinet, such as antennas,terminals, etc., to be sure the set is safe to operatewithout damage of electrical shock.

LEAKAGE CURRENT COLD CHECK(ANTENNA COLD CHECK)With the instrument’s AC plug removed from AC source, connect an electricaljumper across the two AC plug prongs. Place the AC switch in the on position,connect one lead of ohm-meter to the AC plug prongs tied together, and touchother ohm-meter lead in turn to each exposed metallic parts such as antennaterminals, phone jacks, etc. If the exposed metallic part has a return path to thechassis, the measured resistance should be between 1MΩ and 5.2MΩ. Whenthe exposed metal has no return path to the chassis the reading must beinfinite. Any other abnormality that exists must be corrected beforethe receiver is returned to the customer.

ELECTROSTATICALLY SENSITIVE DEVICESSome semiconductor (solid-state) devices can be damaged easily by staticelectricity. Such components commonly are called Electrostatically Sensitive(ES) Devices. Examples of typical ES devices are integrated circuits and somefield-effect transistors and semiconductor “chip” components. The followingtechniques should be used to help reduce the incidence of component damagecaused by static electricity.

1. Immediately before handling any semiconductor component orsemiconductor-equipped assembly, drain off any electrostatic charge on thebody by touching a known earth ground. Alternatively, obtain and wear acommercially available discharging wrist strap device, which should beremoved for potential shock reasons prior to applying power to the unit undertest.

2. After removing an electrical assembly equipped with ES devices, place theassembly on a conductive surface such as an ESD mat, to preventelectrostatic charge buildup or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.4. Use only an anti-static solder removal device. Some solder removal devices

not classified as “anti-static” can generate electrical charges sufficient todamage ES devices.

5. Do not use freon-propelled chemicals. These can generate electrical chargesufficient to damage ES devices.

6. Do not remove a replacement ES device from its protective package untilimmediately before you are ready to install it. (Most replacement ES devicesare packaged with leads electrically shorted together by conductive foam,aluminum foil, or comparable conductive material.)

7. Immediately before removing the protective material from the leads of areplacement ES device, touch the protective material to the chassis or circuitassembly into which the device will be installed.

Caution: Be sure no power is applied to the chassis or circuit, and observeall other safety precautions.

8. Minimize bodily motions when handling unpackaged replacement ESdevices. (Otherwise, seemingly harmless motion, such as the brushingtogether of your clothing or the lifting of your foot from a carpeted floor, cangenerate static electricity sufficient to damage an ES device.)

REGULATORY INFORMATIONThis equipment has been tested and found to comply with the limits for a ClassB digital device, pursuant to Part 15 of the FCC Rules.These limits are designed to provide reasonable protection against harmfulinterference when the equipment is operated in a residential installation. Thisequipment generates, uses and can radiate radio frequency energy and, if notinstalled and used in accordance with the instruction manual, may causeharmful interference to radio communications. However, there is no guaranteethat interference will not occur in a particular installation. If this equipment doescause harmful interference to radio or television reception, which can bedetermined by turning the equipment off and on, the user is encouraged to tryto correct the interference by one or more of the following measures: Reorientor relocate the receiving antenna; Increase the separation between theequipment and receiver; Connect the equipment into an outlet on a circuitdifferent from that to which the receiver is connected; Consult the dealer or anexperienced radio/TV technician for help.

The responsible party for this device’s compliance is:
