Question about Audio & Video Receivers
SOURCE: amp keeps switching off
There is a problem with one or both of the audio amp circuits. The amp is going into a protect mode as to protect and save your speakers. Sorry but there is no simple fix. this will need to go to the shop to be diagnoised. Good Luck

SOURCE: Volume Control
The volume control shaft lube, over time and heat exposure, will flow down and corrupt the contact between the volume twister and the spring loaded sensor. Pull the cover off the tuner, locate the volume control and take out the two screws holding it in. It looks like a small circuit board with the volume twister attached.
The base of the twister is hooked to the circuit panel by four metal tabs. Pry these guys gently away and pull the twister free. There will be a metal disk at the end of the volume control shaft, and will have a goopy lube residue on the face of it that can be cleaned with electric contact cleaner or some other kind of solvent. Wipe it clean,(do not immerse) reattach, and test. Worked perfect for me.

SOURCE: Have bought a Technika DAB
To set alarm mode :- press Alarm 1 or 2 briefly to swtich between choices of Alarm On-Beep / DAB / FM / Off, keep pressing this alarm button until you get to the mode you want then stop pressing and leave to settle.
To set time: Press and HOLD Alarm 1 or 2 to change time. Minutes will flash first, use dial to change numbers, when you've got to the number you want press jog/select to change hour, use dial to change hour number. If you just leave it alone once you've reached the hour you want it will set where you left it, but...
If you want to specify preset channel/volume/beep tone etc keep pressing jog/preset after setting hour and use dial to set your preferences.
