i-Monitor Low Battery Message
If the ENGINE START button is pressed and ''batt'' is blinked on the 
i-Monitor display, the battery voltage is too low to operate the engine's
electric starter. Use the recoil starter to start the generator. Have the
battery recharged and checked (see page 65).
i-Monitor System Error Messages
If the generator has a system malfunction, it will blink an error message
on the i-Monitor display. During remote control operation, an E-01 error
message may display if the ENGINE START button is pressed for more
than 10 seconds. With an E-01 error message, the engine will stay
running and the electrical output may stay constant.
Normal remote control operation will be restored after the E-01 error
message clears automatically. If the E-01 error message does not clear
automatically or if any other error message displays, contact your
servicing dealer.
