About one hour after checkout, the manual was available for download. Clear reading and detailed. Thanks
;
Excellent transaction - clean document received - Thanks a lot
;
Manual is in German but complete. I needed this one to fix a long lasting problem with the internal PSU of the camera. Most of the capacitors begin to leak after a few years wich results in the inability to power on the camera. When you try to turn it on the power led flickers and the unit directly turns off. Thanks to this manual I was able to locate all bad cap's and to dis- and reassemble the camera without any problems.
 ;
We received the manual in a timely manner and it was exactly what we were expecting.
;
Excellant, finally this is want I need and searching for The service manual is fantastic and thank you to owner-manuals.com and its service. Price is reasonable. It's a bit slow on my end in downloading but manage to receive the whole manual without a break. once again, thanks.
KMC-35/36
CIRCUIT DESCRIPTION
Hot Microphone Function
In the Hot microphone state, only microphones whose PTT switch is pressed can send modulation signals in the environment in which several microphones are connected to the transceiver in parallel. In the Normal microphone state, if the PTT switch on one of the microphones is pressed, modulation signals are sent from all microphones.
â� Circuit description
Hot microphone operation can be performed by cutting the jumper (JP1). If the jumper is not cut (Normal microphone state), bias voltage is always applied to the microphone element (Q3 is always ON) and if the microphone mute of the transceiver to which the KMC-35/36 is connected is released, modulation signals can be sent even when the microphone PTT switch is not pressed. If the jumper is cut (Hot microphone state), bias voltage is applied to the microphone element only when the PTT switch is pressed (Q3 turns ON only when the PTT SW is pressed), and modulation signals cannot be sent when the microphone PTT switch is not pressed.
