Automatic Power Save Feature
Your PMR845-2CK radio has a unique circuit designed to
dramatically extend the life of the batteries. If there is no
transmission nor an incoming call within 3 seconds, your radio
switches to the Power Save mode. The radio is still able to
receive transmissions in this mode.
LCD Backlight
The LCD Backlight will automatically turn ON when any key
(except the
PTT
button) is pressed. The LCD display will
illuminate for 10 seconds after the last key press.
