Power commands Command Decimal Code Power toggle 16–12 Power-on 16–123 Power-off 16–124 Note that the C31 also responds to code 20–53 (the PLAY command for an Arcam CD player). The C31 swiches automatically to CD input on receiving this command. Troubleshooting If you are having trouble with your amplifier, check the following items. No sound Check the following: < Both the pre- and power-amplifiers are switched on. < The pre-amp. is not muted (indicated on the C31 by “Muted” being shown on the front-panel). < The selected source is generating audio (e.g., if CD is selected, then the CD is playing). < The tape input is not selected on the C31 (indicated by the light above the TAPE button being illuminated), instead of the expected source. In this case, press TAPE again to de-select the tape input. < The speaker outputs are enabled on the P35, as indicated by the lights above the SP1 and/or SP2 buttons (as appropriate) being illuminated. Sound cuts-out unexpectedly If the temperature of the internal heatsink rises above a safe level, then a thermal cut-out inside the amplifier will operate. During this time, the power indicator on the front panel flashes and the protection system temporarily removes the power to the speakers. The system will reset itself as the heatsink cools down. < With two pairs of low-impedance speakers connected (6. or less), overloads are more likely. Overloading the amplifier may cause it to shut down because of overheating. < Note that, due to the high output voltage from a CD player, it is possible to drive your amplifier at full power even though the volume is not set at maximum. See page 6. Amplifier does not switch back on All the amplifiers detailed in this handbook have a protection mechanism which is activated if you switch the unit on immediately after turning it off. If this mechanism activates, wait 30 seconds then try again to switch the unit on. Guarantee Worldwide Guarantee This entitles you to have the unit repaired free of charge, during the first two years after purchase, at any authorised Arcam distributor provided that it was originally purchased from an authorised Arcam dealer or distributor. This period can be extended to five years if the completed registration card is returned to Arcam. Arcam can take no responsibility for defects arising from accident, misuse, abuse, wear and tear, neglect or through unauthorised adjustment and/or repair, neither can they accept responsibility for damage or loss occurring during transit to or from the person claiming under the guarantee. The warranty covers parts and labour costs for two years from the purchase date (five years upon registration). After this time you must pay for both parts and labour costs. The warranty does not cover transportation costs at any time. Claims under guarantee This equipment should be packed in the original packing and returned to the dealer from whom it was purchased, or failing this, directly to the Arcam distributor in the country o...
