Hello Wowbagger,

I've returned the COM-120A and got a COM-120B instead. Since the sale was in US, I've also sent it in for calibration, just to make sure I can rely on the unit.
Received the monitor two weeks ago and thought, ok, it's a newer model, freshly calibrated, let's buy a new battery for when I'll need some on-site checks. I've bought a Yuasa NPH 5-12 (the previous COM-120A has the same model) and plugged it in.
There is a note in the manual : "...always allow a discharged battery to recharge in Stand-by Mode". That's exactly what I did.
Few hours later, there was some smoke smelling from the back of the unit. Got out the battery and powered on the monitor. Bang! On the "synthesizers" screen, all items were "UNLOCKED", the front green led was flashing. Sending the unit in for repairs was not an option, so the next morning I took out the PSU and did the repair myself (1 x 47 μF tantalum cap toasted) :

The unit works fine now, but I have a few questions :
1. Should I avoid using/charging the battery while AC power is on?
2. Is the COM-120A/B/C series prone for such failures or it's just the age of the unit?
3. What's the best/recommended way to supply power to the unit? using the 12V DC at the back or the regular 100 - 240V AC?
4. Where can I get EasySpan/EasySweep software from? Since it's an option, do I have to pay for it?
5. What's the memory limit for the PCMCIA flash card? Will a 350Mb card work?
I love the unit, it's exactly what I need for my amateur work, but anytime I have to use it becomes scary the thought that could fail on me.
Thanks in advance for your answer.
Best regards,
Raz
