RISK OF ELECTRIC SHOCK

DO NOT OPEN

CAUTION:
TO  REDUCE THE RISK OF ELECTRIC SHOCK, 
DO NOT REMOVE COVER (OR BACK). NO USER 
SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE
PERSONNEL.

This symbol warns the user that uninsulated voltage within 
the unit may have sufficient magnitude to cause electric 
shock. Therefore, it is dangerous to make any kind of contact 
with any inside part of this unit.

This symbol alerts the user that important literature concerning 
the operation and maintenance of this has been included.
Therefore,  it  should  be  read  carefully  in  order  to avoid 
any problems.

T

here are special components used in this equipment which are important for safety. These parts are indicated 

by  the ”

 

Y

 

”  mark on the schematic diagram and the replacement parts list. It is essential that these critical 

parts should be replaced with manufacturer's specified parts to prevent X-radiation, shock, fire, or other hazards.

Do not modify the original design without permission of manufacture.

PCBs (manufactured) using lead free solder (PbF) will have a stamp on the PCB.

8

Lead free solder has a higher melting point than standard solder. Typically the melting points is 35 

°

C – 40 

°

C

(95 

°

F – 104 

°

F) higher. Please use a soldering iron with temperature control and adjust it to 360 

°

C – 370 

°

C

(680 

°

F – 698 

°

F). In case of using high temperature soldering iron, please be careful not to heat too long.

8

Lead free solder will tend to splash when heated too high (600 

°

F / 1112 

°

F).

8

Lead free solder (Sn - 3.0Ag – 0.5Cu) or equivalents are recommended on repairing our lead free soldered PCB.

   WARNING

This service information is designed for experienced repair technicians only and is not designed for use by the 
general public.
It does not contain warnings or cautions to advise non-technical individuals of potential dangers in attempting to 
service a product.
Products powered by electricity should be serviced or repaired only by experienced professional technicians. Any 
attempt to service or repair the product or products dealt with in this service information by anyone else could 
result in serious injury or death.

The lithium battery in this equipment must only be 
replaced by qualified personnel. When necessary, 
contact your local Panasonic supplier.

Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type recommended 
by  the equipment manufacturer. Discard used batteries 
according to manufacturer's instructions.

1. When service is required, observe the original lead dress.

   

Components, wires or cables that indicate evidence of

overheating or other electrical or mechanical damage

should be replaced.

2.

       

After servicing see to that all the protective devices, such

  as insulation tape, shields must be properly installed.

3. 

 

After servicing, make the following leakage current checks

to prevent the customer from being exposed to shock

  hazards.

1.

       

Unplug the AC cord and connect a jumper between the

two prongs on the plug.

2.

       

Measure the resistance value, with an ohmmeter, between

     

the jumpered AC plug and each exposed metallic cabinet

 

             

part on the equipment such as screwheads, connectors,

         

control shafts, etc.

         

When the exposed metallic part has a return path to the

           

chassis, the reading should be between 1 M

Ω

  and 

           

5.2 M

Ω

. When the exposed metal does not have a return

path to the chassis, the reading must be 

∞

  (infinity).

               

Any resistance value below  this range indicates an

abnormality which requires corrective action.

3.

       

Repeat the test with the AC switch in the "OFF" position.

1.

     

Plug the AC cord directly into adaptor socket and plug

 

           

adaptor into the AC outlet. Do not use an isolation

transformer for this check.

2.

         

Connect a 1.5 k

Ω

  / 10 W resistor, paralleled by 0.15 

µ

F

     

capacitor, between each exposed metallic part on the unit

    

and a good earth ground such as a water pipe, as shown

       

in Figure 1.

3.

     

Use an AC Voltmeter, with 1 k

Ω

 / Volt or more sensitivity,

to measure the potential across the resistor.

4.

     

Check all exposed metallic parts of the cover (BNC

    

connector, Handle bracket, Metallic cabinet, Screwheads,

Metallic overlays, etc.), and measure the voltage at each

       

point.

5.

       

Reverse the AC plug in the AC plug adaptor and repeat

        

each of the above measurements.

6. The potential at any point should not exceed 0.75 V RMS.

 

           

A leakage current tester (SIMPSON MODEL 229 or

 

        

equivalent) may be used to make the hot checks.

 

       

Leakage current must not exceed 0.5 milliampere.

       

In case a measurement is outside of the limits specified,

       

there is a possibility of a shock hazard, and corrective

         

action must be taken before returning the instrument to 

          

the customer.
