The front panel LOCK button allows you to
disable the DIAL and/or the front panel con-
trols.

In the transceiver’s default configuration,
pressing the [LOCK] button disables just the DIAL, while the other keys and switches are
unaffected. To lock out the remainder of the controls and the SELECT knob, use Menu
Mode No-054 [LOCK MODE]:

1. Press and hold in the [FUNC] key for one second to enter the Menu mode.
2. Rotate the SELECT knob to recall Menu Mode No-001 [EXT MENU], then rotate the

DIAL to change the setting to “ON” to enable the extended Menu Mode.

3. Rotate the SELECT knob so as to recall No-054 [LOCK MODE].
4. Rotate the DIAL to select the desired configuration:

DIAL:

Locks DIAL knob only.

FREQ: Locks front panel keys and knobs related to frequency control (such as

BAND(DWN) and BAND(UP) key, [A](A/B) key., etc.).

PANEL: Locks all front panel keys and knobs (except POWER and [LOCK] keys).
ALL:

Locks all front panel keys and knobs (except POWER and [LOCK] keys) and
locks the microphone keys.

5. When you have made your selection, press and hold in the [FUNC] key for one second

to save the new setting and exit to normal operation.

When the controls are locked out (small “ ” icon will appear at the bottom right-hand
corner of the LCD), press the LOCK button once more to release them to normal operation.
