Key Lock
Inputs from the keypad may be locked out at any time by holding the
Clear key and pressing the Down key. When Key Lock is active,
KEY.L is displayed at the bottom of the screen as shown below.
Key Lock is deactivated by holding the Clear key and pressing the
Down key a second time. Key Lock only locks out the SP-200’s
keypad. The PTT and Light functions are not affected.
Screen and Keypad Lighting
Press and release the Light Button to activate the SP-200’s screen and
keypad lighting for five seconds. To activate the screen and keypad
lighting indefinitely, press and hold the Light Button for one second
until a beep is heard. When this is done, the Light Button must be
pressed a second time to turn the lighting off.
Last Frequency
Pressing the Last Frequency button allows you to toggle between your
last two frequencies—great for switching between ground and tower.
