Battery Charge Status
Your radio can indicate the battery’s charge status
through:
• the LED and sounds.
• the fuel gauge icon on the display.
You can also check the battery charge status via the
menu entry. See IMPRES Battery Annunciator on
page 104 for more information.

pressed.

tone).

the battery voltage drops to low level. In this case,
