CAUTION: DO NOT short pin 1 to ground as this can 
damage the internal 9 V regulator. DC voltage is applied 
to pin 1 for microphone operation. Take care when 
using a non-Icom microphone.

Make sure the back up battery is correctly 
connected. Use a cable with following 
current capacity. Solder or clamp the cable 
lug when connecting the power cable to the 
backup battery to prevent voltage drops.
