The previous reply is for Opticon with an 'N' not 'Opticom' with an M and a different company, so not very helpful. I haven't found an online copy of the manual so far.
1. Lift up the handset.
2. Press the STO button (for 'Store')
3. Key in the full number you want to store, e.g. 01234 5678910
4. Press STO again
5. Press one of the numbers on the key pad that you want to be the Quickdial number, from 1 to 0.
6. Press the MEM (Memory) button.
7. Replace the handset in its cradle.
8. The Quickdial number will now be stored and you can call it by lifting the handset (or pressing the speakerphone button) and then pressing the MEM button followed by the single number you chose, e.g. MEM then 3.

I have a Baumatic P650SS oven. To adjust the timer volume, wait until it is beeping and then press the minus button and it will adjust through 3 sound levels. Release the minus button and the sound level of the audio signal will be set.
