RE: DM 15L keypress problems
It's true that the minimum time interval required between two keystrokes is shorter in the 48MHz mode of the DM15L; for me it's still problematic because it slows me down while typing even in the fast mode.
I have sent a report to SwissMicros. It's the ONLY element where the HP15cLE is still better than the DM15L. Roman |

RE: DM 15L keypress problems
UPDATE: I reported the "fast-type" keystroke loss issue to SwissMicros. They suggested that I remove the battery and short-cut the calculator. I'm happe to report that this simple step removed all problems regarding lost keystrokes immediately.
I know it's the very first thing I should have done before going public with this issue, but I thought it's a firmware problem, similar to the random key press losses that are observed with firmware v16. SwissMicros is a company with excellent customer service. Roman |

Yes, sorry, that's what I wanted to say. Thank you.

A matte finish would probably do fine, and it's be easy to apply if you can disassemble to remove the key pad from the openings of the key plate. |

I'm happy to report that this simple step removed all problems regarding lost keystrokes immediately.I was growing concerned about that key press loss problem when typing quickly on my 16L (I don't use the 15L nearly as often), which had become worse after I upgraded to v21, and I found your message. I gave it a try and, sure enough, no more key problem. *** Wow, that's a relief ! *** Let's add a smiley to emphasize : I wonder how all this unnecessary worrisome issue started, since it can be fixed so easily. |

RE: DM 15L keypress problems
I have the keystroke problem at 12MHz. Fast 3x typing a number often leads to just 2 numbers. At 48MHz problem disappears. I will send an email with a video to Swissmicros.

I will send an email with a video to Swissmicros. Same here with a just purchased DM-15L (M1B V21 S/N# 01248). At 48 MHz it works flawlessly. A question, the ON+1/x string reports, after the battery voltage, the letters "RTC". What do they mean? Evenmore, there's a piezo buzzer inside. I suppose that RTC means "Real Time Clock" and that both it and the buzzer are used in the DM-41L incarnation of this hardware but, are any of them accessible from the 15L software? Regards. |
