‐ see the Advanced Settings section for details. The instructions above
reflect the factory default behavior of the "Assume leading 1 / 100 MHz"

Keypad Lock
Keypad Lock is used to protect against accidental button pushes, such as
when your DX15 is worn on a belt and you want to monitor only a single
frequency.
To activate Keypad Lock:
 Press and hold the LOCK button.
 After a moment, the Keypad Lock icon will appear on the display.
Keypad Lock inhibits all keypad buttons, except for the following:
 Push‐to‐Talk (PTT) button works normally.
 Emergency button works normally.
 LIGHT button works normally.
To cancel Keypad Lock:
 Push and hold the LOCK button until the Keypad Lock icon disappears.
 All keypad buttons / behaviors will now function normally.
Note: The Keypad Icon, when flashing, is used to denote a Memory
Channel that will be skipped when scanned. See the Memory Channel
section for details about that behavior.
