TM Further Information
Due to the nature of our digital sound processors, there are operational tips too numerous to include in an instruction
manual such as this. For additional information, please visit our website at

technical support and customer discussion forums, together with a downloads section for software updates, technical
papers etc.
Troubleshooting
Power LED not lit : Is the Remote switch cable from the source unit (Cassette or CD Player) attached to the REM terminal
of TOTAL RECALL, and is the source unit switched on? Are the +12V and GND (Ground) terminals connected correctly?
Is the Ground cable properly attached to the chassis of the vehicle or to an existing ground point that is known to be OK?
No Sound : With TOTAL RECALL connected to your PC (running the PC EDITOR) or the optional Programmer, check
that none of the channels are set to MUTE. Adjust the level of the channel output gain controls. Are the Input and Output
signal cables correctly connected? If there is only sound from one channel of a pair (Front or Rear), swap the Left and
Right channel Input cables at the processor - if the fault moves to the other channel then the fault is with the cable or
source unit. If the fault remains in the same channel, isolate which speaker is not working and trace it back to the
relevant amplifier channel, and then back to the outputs of the processor. At the processor, swap the Left and Right
channel Output cables. If the fault still remains on the same
speaker then the fault is with a cable or a unit after TOTAL
RECALL (the power amplifier or the speaker itself). Check the amplifier gain controls and any input switching options
(such as built-in crossover networks). If the fault moves to the other
speaker then your TOTAL RECALL may be faulty-
leave it installed in your system and return to your dealer so that they can check it.
Distorted Sound or Low Volume : Adjust the Output Gains of TOTAL RECALL via the PC EDITOR or optional Programmer.
Adjust the Input Level Controls of the power amplifier (and input/output controls of any additional processor, if applicable).
Check if the amplifier has a built-in crossover network - is it switched correctly?
