Static electricity
may have been
discharged into the
LCD display.
Refresh display: Press and
hold the MENU/HOME button for
10 seconds.
The LCD text
display is
locked-up,
pressing any

no response
- may show

The RJ11
connections on the
communication cable
are not making a
good connection.
Reset remote: 1) disconnect
the remote cable from the
inverter for 5 seconds and
then reconnect; 2) check RJ11
cable connection on back of the
remote (see Figure 2-2).
Important:
Ensure the RJ11
connector is pushed into
the correct port. You should
feel/hear “click” when the
connection is made.
The remote is not
getting suf
fi
cient
power from the
inverter.
Ensure the inverter batteries
are connected and the inverter
is operating correctly. The
inverter should be able to invert
and power AC loads from the
batteries (ensure no AC power
is connected to the inverter’s AC
inputs).
The LEDs and
the backlight
are off.
The remote is in
Power Saver mode.
Press any button to reactivate
the remote (or turn the
Power
Saver
setting to
Off

non-functional
(no lights, no
text on LCD
display, and no
response when
pressing any
button).
The communication
cable is bad or not
correctly connected
to the Remote port
on the inverter.
Check the communications
cable from the inverter to
remote; ensure: 1) it is
connected to the Remote port,
2) the correct communications
cable is used (a 4-conductor
telephone cable may be
substituted to determine if cable
is good).
Inverter is not
connected to
batteries.
Ensure inverter batteries are
connected and the inverter is
operating correctly without any
AC power connected (should
be able to invert and power AC
loads from batteries).
