and then they revert to normal

The LCD displays a bootup sequence which con-
sists of four screens:

peared. The unit will then power down.
Initial Power Off
Timer Screen
If the AUDIO and FREQ
buttons are released before
the LCD goes blank at the end
of the countdown, the unit will
not turn off. Instead, it will stay
energized and the LCD will return to the previous
screen.
NOTE: If batteries are removed or reach the end
of life while the unit is turned on, the unit will turn
back on with a brief, simultaneous press of the
AUDIO and FREQ buttons. The counting sequence
will not be displayed in this instance.
Automatic Power Restore
The firmware will remember the power on/off state and
the settings when batteries reach their end of life or are
removed. When fresh batteries are installed, the unit will
reboot and return to the previous settings without the
need to press any buttons. This only works when the
unit is fully on and transmitting.
It does not work in the
Standby Mode.

the LCD while the unit is in the standby mode.
