Lock/Unlock Screen
Simultaneously pressing and holding both the UP and
DOWN arrow buttons during normal operation starts the
Lock timer. The timer starts at three and counts down to
zero. When the timer reaches zero, the keypad controls
are locked.
The LCD will display the locked condition as long as the
arrow buttons are held, then revert back to the previous
screen when either button is released.
With the controls locked, the AUDIO and FREQ buttons
can still be used to display current settings. Any attempt
to change a setting by pressing either the UP or DOWN
arrow button will result in an on-screen Loc reminder
that the controls are locked. Remove the batteries to
unlock the control panel.
Important: Once the transmitter is locked,
it cannot be unlocked or powered off using
the buttons. The only way to unlock a locked
transmitter is to remove the batteries.
