Technics CH900 - how do I remove/clear a saved station preset?

[RageVector]

I've recently bought a CH900 system from ebay.
it works fine.

I followed the instructions to get it to automatically tune in FM Stations, however it has tuned in a number of useless 'noise' stations.
Any idea of how to remove these?
I have downloaded the available CH900 manual, but there is nothing there that I have noticed on how to remove a preset.

Why not just ignore/not use those presets or, on most equipment do a manual tune and store another station in the problem presets which usually overwrites what's stored.

Thanks for the reply JayCee.
I dont want to ignore them. The tuner has a large but limited number of preset stations and I just want to remove the hissy ones and the rubbish ones.

The manual doesn't cover deleting or resetting unfortunately

Can't you just select one of the unwanted presets and then rescan until it finds a wanted station then normally you would push and hold that preset button for a few seconds until the station is stored...sometimes you get a confirmation beep.
