SERVICE MANUAL
JAN.2005
Use this manual as a supplement to
"New B-3 SERVICE MANUAL."
*

Great care has been taken in the design and manufacture of this product to assure that no shock hazard exists on any exposed
metal parts. Internal service operations can expose the technician to hazardous line voltages and accidentally cause these
voltages to appear on exposed metal parts during repair or reassembly of product components. To prevent this, work on these
products should only be performed by those who are thoroughly familiar with the precautions necessary when working on this
type of equipment.
To protect the user, it is required that all enclosure parts and safety interlocks be restored to their original condition and the
following tests be performed before returningthe product to the owner after anyservice operation.
Plug the AC line cord directly into a line voltage AC receptacle (do not use an isolation transformer for this test) and turn the
product on. Connect the network (as shown below) in series with all exposed metal parts and a known earth ground such as a
water pipe or conduit. Use an AC Voltmeter of 5,000 ohms per volt or higher sensitivity to measure the voltage drop across the
network. Move the network connection to each exposed metal part (metal chassis, screw heads, knobs and control shafts,
escutcheon, etc.) and measure the voltage drop across the network. Reverse the line plug and repeat the measurements. Any
reading of 4 volts RMS or more is excessive and indicates a potential shock hazard which must be corrected before returning
the product to the user.
SAFETYNOTICE
CAUTION
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.
