SECTION  7 

TROUBLESHOOTING 

If  your  Vanguard  does  not  appear  to  be 

working properly,  you  should  first of all 

run  through  the  following  simple 
checks: 

1. 

Check  that  the  handset  has  been 

replaced  properly  on  Vanguard  and 
any  other  phones  connected  to  the 
same  installation. 

2. 

Ensure  that  the  plug  is  inserted 
correctly  into  the  wall  socket. 

3. 

Check that the operating instructions 
have  been  followed  correctly. 

4. 

Check  that  the correct signalling and 
recall  modes  have  been  set. 

5. 

Check  that  the  tone  caller  is  not 

switched  off. 

6. 

Check that  the total REN value  does 
not  exceed 

4. 

(See  Section 

9.4) 

If The Problem  Still  Persists ....... . 

You can  try two simple tests yourself to find 
out  whether  the  fault  lies  with  your 
Vanguard,  the  exchange  line  or  any  other 
telephones  you  have. 

1. 

If  you  have  a  second  telephone  that  is 
working  connect  your  Vanguard  to  that 
socket and dial  a  number.  If you  still can't 
make a  call  your  Vanguard  may  be  faulty. 

2. 

If  your  Vanguard  is  your  only  telephone 
but  you  have  more  than  one  socket  you 
can  find  out  whether  your  Vanguard  or 
your  socket  is  faulty  by  plugging  into 
another  socket. 

If  a  fault  is  still  suspected,  and  your 

Vanguard is  rented,  you  should  contact your 
local  British  Telecom  Fault  Service.  The 
number is  usually 

151 

but check  your Phone 

Book. 

British  Telecom  engineer  may  be 

able  to  give  you  more  advice  and  may  also 
be  able  to  carry  out  a  remote  test  on  your 
installation. 

When  necessary, 

if  your 

Vanguard is  rented,  a visit  to  your premises 

will 

be  arranged.

SECTION  8 

MAINTENANCE 

If your Vanguard is  rented,  the rental charge 
covers  any maintenance that may be needed 
from  British  Telecom.  Your  Vanguard  has 
been  designed  to  give  you  years  of  trouble­
free  service,  provided  it  is  looked  after 
properly. 

Do  not  try  to  adjust  or  repair  your 

Vanguard yourself. 

There is no part of the 

phone that you can service and any thing you 
may  try  to  do  could  possibly  make  the 

situation  worse. 

Care  of your  new  Vanguard 

To  preserve  the  appearance  of  your 
Vanguard  avoid  leaving  it  exposed  to  direct 
sunlight  which  may  fade  the  colour  of  the 
case. 

To  clean  it  simply  use  a  damp  cloth  - do 

not use abrasive or  aerosol cleaners,  both of 
which can  cause problems either to the case 
or  the  circuitry  inside. 

The  Vanguard  is  an  electrical  device  and 

so  you  should  avoid  using  it  near  a  bath. 

Finally,  try  not  to  twist  or  knot  the  coiled 

cable.
