PTT: The PTT switch is locked (TX not possible)
KY+PTT: Both the keys and PTT switch are locked out
To lock out some or all of the keys:
1. Press and hold in the [TXPO] key for one second to enter the Set mode.
2. Rotate the DIAL knob to select Set Mode Item 46: LOCK.
Note: Do not forget to pull the DIAL knob to rotate the DIAL knob.
3. Press the [TXPO] key momentarily to enable adjustment of this Item.
4. Rotate the DIAL knob to choose between one of the locking schemes as outlined above.
5. When you have made your selection, press the PTT switch to save the new setting and return to
normal operation.
To activate the locking feature, press the [F/W] key, then press and hold in the [BAND] key for one second.
The “Key Lock” icon will appear on the LCD. To cancel locking, repeat this process.
