-SERVICE INFORMATION-
1. Resistance values are indicated in ohms unless
otherwise specified.
(K= 1,000, M=1,000,000)
2. Capacitance values are shown in microfarads
unless otherwise noted.
(P=Picofarads)
3. All voltages are refered to ground under the fol¬
lowing conditions.
DC: No signal except where indicated.
AC: Rms
4. - PRECAUTION -
a
a) All components marked /:\ must be re¬
placed only with original type specified by the
manufacturer, electro-voice and installed as
the original with spacers and positioned away
from adjacent components where applicable.
b) All soldering must be down in a professional
manner using solder with resin core only.
c) All covers, shield and insulating spacers must
be replaced before returning appliance to
customer.
d) A damaged power supply cord must be re¬
placed before returning appliance to cus¬
tomer.
e) A dielectric test consisting of 1500V AC 60Hz
is to be applied between both blades of the
power supply cord attachment plug and the
exposed conductive surface of the appliance
for a period of not less than one second be¬
fore returning to appliance to customer.
f) The-^MArE- marked resistors are mounting
above the P.C.B. on sleeves.
