Excellent service from this company (including a total refund on an earlier purchase when through no fault of the company the manual was incomplete). I have purchased several manuals which I have been very satisfied with, as I am with this one. Highly recommended.
 ;
It was easy to order and received exactly what I needed. Only complaint would be the 24 hours you have to wait.
;
Manual was delivered in a timely manner and was all in English as advertised. The manuals I received when we moved into our flat were in German, Italian, and French. Having never used a steamer before, and not speaking/reading German very well, I needed an English Manual. this was a huge help.
;
Great Manual. This manual is available no where else. It was exactly what I was looking for. Only in German.
;
This GRUNDIG UV5A Owner Manual is not only an instruction manual but a total functional circuit description of the Multimeter and includes circuit diagram at the end pages. It is very helpful for repairing and calibrating the instrument. It is written in two languages English and German for international support. It was very easy to repair my unit with this document. Regards, Regis Pauly, Electrical Engineer.
6BSST
THREE CHANNEL POWER AMPLIFIER
Front Panel
1. 'SST POWER' switch The front panel label 'SST POWER', is a touch sensitive membrane switch used to apply or remove a/c line power to the 6BSST circuitry. Push firmly the center of the switch until the power-up sequence begins. Push again and the 6BSST will power-down. ( Note: the rear circuit breaker must be on for the 6BSST to power-up) 2. LED Indicators Each 6BSST channel has a LED indicator to monitor the following channel conditions: UNLIT indicates channel has no power. RED indicates channel is muted (power-up-down sequence) GREEN indicates channel operation is normal. FLASHING RED - indicates channel clipping. ORANGE indicates channel thermal shutdown. Power up sequence After pushing the 'SST POWER' switch, each channel led will turn from unlit to red (mute). When the power supplies have stabilized the channel will come out of mute and the led will change to green (normal operation). Unlit led ( No power ) The 6BSST channel led when unlit indicates no A/C mains power is present at the channel. If all channel led indicators are unlit the 6BSST probably needs only to be powered on. A single led not lighting possibly indicates blown channel fuses. When checking fuses switch off the circuit breaker on the rear panel, or unplug the power cord. Use only the specified quick-acting 4 amp 250V 5mm x 20mm fuses. See page 6 for the fuse locations. Clipping ( flashing red ) Clipping occurs when the channel output level no longer can follow the level increase at the input (Over driven outeeput condition). When a 6BSST channel is driven into clipping the channel led will change from green to red then back to green when the level is reduced ( Flashing Red ). Momentary clipping can be tolerated, however it indicates that maximum un-distorted power has been surpassed and potential speaker damage may result if overload conditions persist. Any amplifier that is constantly operated into clipping indicates a more powerful amplifier is needed for that application. Thermal Shutdown ( orange ) The 6BSST channel has thermal shutdown circuitry to prevent damage due to overheating. Should thermal shutdown occur, the channel will mute, and the channel led will turn orange indicating this condition. When the channel has cooled to a safe operating condition the channel will return to normal operation. Persistent Thermal shutdown indicates steps need to be taken to increase airflow across the channel or channels heat sink. ( Also see installation section on ventilation ).
