[ICOM] IC-756PROII Operation

[John Hart]

Does anyone know if the IC-756PROII can be safely operated while standing on it's rubber feet (the ones located on the right side)?  I can not find anything in the manual about the operation in a vertical mode.  I will be using my ProII for Field Day on RTTY and PSK-31 run remotely via the MixW software.  My desk work area is limited and I won't need to access the controls.  I only plan to run the transmitter at about 70 watts due to the duty cycle of RTTY and PSK-31.  
 
Note:  My ProII has been modified to allow the cooling fan to run at half speed on receive and goes to full speed as needed in transmit.
