Troubleshooting

 

Most problems are usually simple issues that can often be found by careful inspection  of the 
diver  communicator,  diving  umbilical,  and  diver  helmet  wiring.  The  following  section  will 
describe  the troubleshooting procedure for several common issues. If these sections  do  not 
cover your particular issue, it is recommended that the diving umbilical be disconnected from 
the  diver  communicator  and  the  check-out  procedures  in  section  5.1  be  conducted.  If  the 
diver  communicator  passes  the  check-out  procedures  then  the  issue  is  most  likely  in  the 
umbilical connections, the umbilical itself, or the wiring of the diver's hat/helmet 

5.4.1 

Connection Issues 

Most  diver  communicator  problems  are  caused  by  bad  connections.  Making  good 
connections  will  result  in  years  of  good  communications.  For  longer  life,  all 
connections  should  be  soldered  and  copper  wire  must  be  tinned.  It  is  strongly 
suggested  that  dual  banana  plugs  be  used  topside  to  provide  convenient  and 
secure connections. 

All cable splices must be soldered. Splices should be staggered and covered with 
shrink  tubing  (preferably  shrink  tubing  with  an  adhesive  sealant)  and  a  general 
splice  cover  to  protect  the  connections.  Potting  the  splices  to  create  a  reliable 
splice is preferred but not necessary to create a reliable splice. A great number of 
problems  are  very  simple  failures  and  can  often  be  found  by  a  very  careful  and 
close inspection of the unit or system. Logical deductions and equipment familiarity 
can often reduce the suspected area to just one component or circuit. Often upon 
examination,  clues  are  revealed  which  can  also  aid  in  locating  and  correcting  the 
problem.  Visual  inspections  should  include  checking  all  screws  for  tightness,  all 
solder joints for correctness, broken parts, corrosion, electrolysis, foreign material, 
check  connectors  for  proper  insertion  and  alignment.  Check  to  see  that  unit  is 
turned on, speaker on. 

5.4.2 

Low Battery Indication 

The  BATTERY  CONDITION  INDICATOR  indicates  the  battery  level  or  state-of-
charge by monitoring the battery voltage. It is recommended that the 2825R-XX be 
recharged for at least 10 hours if the BATTERY CONDITION INDICATOR is low or 
bad.  If  the  BATTERY  CONDITION  INDICATOR  indicates  a  low  (blinking  LED)  or 
bad  (off  LED)  after  charging,  then  either  the  battery  is  bad  and  needs  to  be 
replaced or the charger has malfunctioned. 

5.4.3 

Unit Not Operating 

The most common reason that a diver communicator appears to be dead when the 
POWER SWITCH and SPEAKER SWITCH are turned on is a bad battery or loose 
AC connection. 

If  the  battery  and  AC  connections  appear  good  and  the  communicator  fails  the 
check-out  procedure,  then  remove  the  screws  holding  the  lid.  Verify  that  the 
connectors on the Printed Circuit Assembly (PCA) are firmly seated. Check that the 
wire  harnesses  are  soldered  to  the  various  connectors,  controls,  and  speaker. 
There should be no loose wires in the system. Remove the fuse from the PCA. It is
