The SELECT button is used to switch the TM500A between the
different meters and modes. One of the LEDs located above the buttons
illuminate, indicating the active function.

The RESET button is used to change the metering parameters and to
reset the CHARGED indicator.
INVERTER ON/OFF Button
The INVERTER ON/OFF button remotely controls the inverter’s ON/
OFF function via the RC4 or RC8 remote control jack. This button
duplicates the function of the inverter’s power switch. The LED
duplicates the indications of the RC8 remote control. Refer to the RC4/
RC8 documentation (supplied with the cable) for LED indications and
modes available (depends on inverter). Remote control cables are
available in 10, 25, 50 and 100 foot lengths. This button/LED does not
function if a remote control cable is not connected or if the inverter does
not support an RC4 or RC8 remote control.
