Logic L55 dab 15 radio how do I tune it as do have the manual

You don't tune a DAB radio - you use a command in the menu and the radio searches for stations, some of which can be saved in the memory buttons, saved to favourites, etc.

Use the rotary Tune/Select control on the HiFi itslef, or the two triangle buttons on the remote control to highlight each mode option until it goes to DAB Radio or FM Radio.

Short press the Tune/Select control on the HiFi or the Select button on the remote control to select the option.

If that works, the manual at the link below is compatible with your equipment.

Lowry Dob or DAB radio???

If the latter, you don't have to tune it at all, DAB is a Digital Audio Broadcast radio and when you first plug it in you should find a button somewhere with setup or search on it, press this and Voila, you have magic happen.
Try it, it's great.

I hope this helps and by the way it's not a CB/2-way radio if it's DAB.

Cheers,
Peter

Forget DAB!

Original manual found - note the Model No. is listed as SC-EN38DB i.e. complete system (main unit = SA-EN38DB; speakers = SB-EN38; remote control = N2QAYB000245):

"Press and hold (PLAY MODE) until 2DAB AUTO SCAN' appears. When a frequency is tuned by Auto scanning on this unit, the ensemble corresponding to the frequency is displayed for approximately 2 seconds"

This is SwannerX and I have solved the problem by locating the DAB radio receiver to a higher position ( some 6ins. higher only ) and orienteering the aerial in an opposite direction.
All 25 stations now tune O.K. and signal quality still reads in the high 90's and signal strength shows 9-10 bars. This is not substantially any more , but it has done the trick!!!
I am still very puzzled why it would not work again in the original position where it has worked well for many years.
Obviously DAB requires a good strong signal as I am living very close to the transmitter at Mounteagle in the Black Isle and the set is upstairs in the house to achieve the highest signal into the set's whip aerial.
Another annoying query I can give you is this :- Every time I do a full AutoTune operation on the DAB receiver , it ALWAYS comes ON tuning BBC Asian 1st. so that station comes up as a 'Favorite' on the Radio's screen. No matter how many other stations I select and listen to for at least 20secs. say, the BBC Asian one STILL is listed as a FAV.
Is this a peculiarity of the Sharp design or a function of the transmission system?
Maybe this BBC Asian is on the first freq. the DAB Radio scans, but I would have thought it would come ON every time with the last station which was selected before it was switched OFF.
What do you think ???

Just bought the same unit but the instruction manual was double dutch. After messing around for a while I managed to do it like this. Whe the unit is set to DAB, Press the Sel+/TU+ or the Sel-/TU- button on the unit (not the remote) until the DAB station displays and then press the Select CH+ button again on the unit. Wait a few seconds while the word "tuning" is displayed and that station should now play. To save the station as a preset do this. When the station is playing use the remote and press the PRG/MEM button once. Then press the number for which preset you want that station to be. The station will be saved. EG to save Radio 1 as Preset station 1, play Radio 1, Press PRG/MEM, then press number 1. After that whenever you press number 1 on the remote Radio 1 will play. Do the same with any other station you wish to save. To save station 10 press the 0/10 button on the remote. To save station 11 press 10+ then 1, 12 is 10+ the 2 etc. Good luck Dopeyemma
