The radio remains on and the battery charges as long as power is being supplied by the vehicle.
Note:
If the radio is connected to the PC over USB and the vehicle power is removed, the
PC will power the radio and charge the battery. If the PC is not externally powered this will
drain the PC battery over time.
Turning the Radio On or Off
■
Turn on while using battery power:
Press and hold the button for three seconds (until the Power LED turns green) to turn the
radio on.
■
Turn off while using battery power:
Press and hold the button for three seconds (until the Power LED turns white) to turn the
radio off.
■
Turn on while using external power:
The radio is always on when using external power.
When a portable IMR is connected to an energy source with the USB cable, pressing the
button turns the power LED green until the button is released, but it does not turn the radio
off.
When an IMR-FT is connected to 12V DC vehicle power, pressing the button turns the
power LED green until the button is released, but it does not turn the radio off. The IMR-FT
radio remains on as long as it is powered by the vehicle.
Important!
To preserve battery energy, a radio not connected to external power
automatically shuts down after one hour of inactivity. If this occurs, turn the unit on
as described above.
