RE: Elektronika MK-61 - today I ordered one NIB
Concerning the MK-61 Russian User Guide contents, is anyone aware of this MK-61 operation requirement, referred in the initial Chapter 1 - "Notice to Owners", point 1.8.:

"After turning off the MK, allow a minimum of 30 seconds before switching it on gain."

Whatever the reason for such recommendation, I'm following it by the letter, just in case... I wonder if some sudden deaths reported for this calculator are related to this small detail.


In addition to the above, there are two more remarks concerning the operation safety rules:
1. "Plugging the external power supply adapter to the 220V outlet power while the calculator is not connected to the adapter, is prohibited".
2. "The use of rechargeable batteries is prohibited".
