ACTIVATING THE TONE FUNCTION

To activate Tone, press [F], [CALL].

• As you press [F], [CALL], the selection cycles as follows:

“OFF” ➞ “TONE” ➞ “CTCSS” ➞ “DCS” ➞ “OFF”.

• “T” appears on the upper part of the display, indicating that

the Tone function is activated.

Note: You cannot use the Tone function and CTCSS/ DCS functions

simultaneously. Switching the Tone function ON after having

activated the CTCSS/ DCS functions deactivates the CTCSS/ DCS

functions.

(default setting).
