Very often our digitor F-8013 will delete the outgoing message of its' own accord, either whilst it is switched off or overnight whilst the unit is still on. This results in patients calling in and receiving the standard message. I have a 9volt battery in the back as a back up power supply. Also sometimes the unit displays Cr, and I cannot find this in the instruction manuel. Do you have any ideas as to what the problem may be?

Hello Check the putput wirings to speakers. If any of them has short circuit, the set will go to protection mode. You can understand it well, as it did worked fine at the repair shope. The set has no fault at all, but the wirings, connects to it have. Just power ON the set at your home, without connection any output or input to it. See, it will not show any protection mode display. Switch it OFF. Connect the output to speakers, one at a time, and switch ON the set. Just do it for all other speakers. This way, you can find out, which speaker line causes the set to go to protection mode. Fine out the reason. Never connect any input to the system, until works fine with out showing any protection display. I helped you somewhat fine, I assumes. Ok.
try the hard reset method ,that is, remove the battery and then insert
the battery and switch the radio on ,it will help you.Otherwise try to
tune the radio to required frequency by changing in the settings and
Only if the amplifier specification will accept the IMPEDANCE which will be low or high according to the connection, if series or parallel.So check this out. Also the phasing should be correct,. the polarity of positive and negative to the amplifier.
I recently looked at the **** Smith Electronics website for support on this product and could find none. Their search facility appears to be designed to expose more and more product for one to buy rather than to give any form of support either technical or in the form of manuals. DSE titles itself as the "Know it alls" of electronics. I'll leave it to readers to decide if they would want to deal with a company that appears to be into Selling Boxes rather than promising any kind of product support beyond under warranty replacement.
I wonder if anyone can help explain what the likely problem will be with my Arcam AV300 amp. Whilst watching TV for no particular reason an extremely loud (what i can only describe as feedback) sound comes out of my B & W speakers for approximately 3 seconds, then silence as the Arcam switches off, I’m then unable to switch it back on for a period of time, (this varies between 5minutes to a few hours) when it eventually switches back on everything seems to be working perfectly. This has happened quite a number of times although it’s intermittent & occurring every 1 - 6 weeks.
I have fixed the display on a Sangean PR-D3L that had faded to less than 30%. It was a bit involved and required pulling the radio apart and desoldering a metal sheild off the back of the display board to reveal the "zebra strip" connector for the display. I used a bit of heat and pressure on the connector strip where it contacts the circuit board - presto 100% display. Don't know how long it will last tho'.
Firstly, the fuse is just a slow blow 1 Amp short style. You should be able to get an equivalent at any electronics parts supplier (a 1.25-1.5 Amp will do as long as it is the correct physical size).
Secondly, the cause of it blowing the mains fuse is probably a short in the primary winding of the Toroidal transformer. I have now replaced the transformer in mine twice over about 4 years.
If you cannot get the original Toroidal transformer (with the correct connectors) use a 50 or 80VA 12+12V Toroidal Transformer and connect the secondary windings in series. You should be able to get one for AU$30 to AU$40.
