by  Vocopro  may  void  your  authority,  granted  by  the 

FCC, to use this product.

2.  IMPORTANT

:  When  connecting  this  product  to 

accessories  and/or  another  product  use  only  high 

quality  shielded  cables.  Cable(s)  supplied  with  this 

product  MUST  be  used.  Follow  all  installation 

instructions.  Failure  to  follow  instructions  could  void 

your  FCC  authorization  to  use  this  product  in  the

3.

 

NOTE

: This product has been tested and found to 

comply  with  the  requirements  listed  in  FCC 

Regulations,  Part  15  for  Class  "B"  digital  devices. 

Compliance  with  these  requirements  provides  a 

reasonable  level  of  assurances  that  your  use  of  this 

product  in  a  residential  environment  will  not  result  in 

harmful  interference  with  other  electronic  devices. 

This  equipment  generates/uses  radio  frequencies 

and,  if  not  installed  and  used  according  to  the 

instructions  found  in  the  owner's  manual,  may  cause 

interference  harmful  to  the  operation  of  other 

electronic  devices.  Compliance  with  FCC  regulations 

does not guarantee that interference will not occur in 

all  installations.  If  this  product  is  found  to  be  the 

source  of  interference,  which  can  be  determined  by 

turning the unit "Off" and "On", please try to eliminate 

the problem by using one of the following measures:

Relocate  either  this  product  or  the  device  that  is  

being affected by the interference. 

Use power outlets that are on different branch (circuit 

breaker or fuse) circuits or install AC line filter(s).

In  the  case  of  radio  or  TV  interference, 

relocate/reorient the antenna. If the antenna lead-in is 

300-ohm  ribbon  lead,  change  the  lead-in  to  coaxial 

type cable.

If  these  corrective  measures  do  not  produce 

satisfactory  results,  please  contact  your  local  retailer 

authorized  to  distribute  Vocopro  products.  If  you  can 

not  locate  the  appropriate  retailer,  please  contact 

Vocopro, 1728 Curtiss Court, La Verne, CA 91750.

(1) 

To  ensure  the  finest  performance,  please  read  this 

manual  carefully.  Keep  it  in  a  safe  place  for  future 

reference. 

(2) 

Install  your  unit  in  a  cool,  dry,  clean  place  -  away 

from  windows,  heat  sources,  and  too  much  vibration, 

dust,  moisture  or  cold.  Avoid  sources  of  hum 

(transformers,  v  motors).  To  prevent  fire  or  electrical 

shock, do not expose to rain and water.

(3) 

Do not operate the unit upside-down.

(4) 

Never  open  the  cabinet.  If  a  foreign  object  drops 

into the set, contact your dealer.

(5) 

Place  the  unit  in  a  location  with  adequate  air 

circulation.  Do  not  interfere  with  its  proper  ventilation; 

this will cause the internal temperature to rise and may 

result in a failure.

(6) 

Do not use force on switches, knobs or cords. When 

moving  the  unit,  first  turn  the  unit  off.  Then  gently 

disconnect the power plug and the cords connecting to 

other equipment. Never pull the cord itself.

(7) 

Do  not  attempt  to  clean  the  unit  with  chemical 

solvents: this might damage the finish. Use a clean, dry 

cloth.

(8) 

Be  sure  to  read  the  "Troubleshooting"  section  on 

common  operating  errors  before  concluding  that  your 

unit is faulty.

(9) 

This  unit  consumes  a  fair  amount  of  power  even 

when  the  power  switch  is  turned  off.  We  recommend 

that you unplug the power cord from the wall outlet if the 

unit  is  not  going  to  be  used  for  a  long  time.  This  will 

save  electricity  and  help  prevent  fire  hazards.  To 

disconnect  the  cord,  pull  it  out  by  grasping  the  plug. 

Never pull the cord itself.

(10)

 To  prevent  lightning  damage,  pull  out  the  power 

cord and remove the antenna cable during an electrical 

storm. 

(11)

 The  general  digital  signals  may  interfere  with  other 

equipment  such  as  tuners  or  receivers.  Move  the 

system farther away from such equipment if interference 

is observed.

NOTE:

Please  check  the  copyright  laws  in  your  country  before 
recording  from  records,  compact  discs,  radio,  etc. 
Recording  of  copyrighted  material  may  infringe  copyright 
laws.

CAUTION

The apparatus is not disconnected from the AC power source 
so  long  as  it  is  connected  to  the  wall  outlet,  even  if  the 
apparatus itself is turned off. To fully insure that the apparatus 
is indeed fully void if residual power, leave unit disconnected 
from the AC outlet for at least fifteen seconds. 

CAUTION:
