Your microTALK
®
radio can automatically scan the CTCSS privacy codes (01 to 38) within
one (1) channel.
To Scan Privacy Codes:

remain on that channel/privacy code for ten (10) seconds.
While setting CTCSS privacy code scan, if you do not press any buttons for fifteen (15) seconds your radio will automatically return to LISTENING
MODE on the channel/privacy code that was displayed before you entered Mode Functions.

If you press the TALK button while scanning and not within ten (10) seconds of receiving a transmission, you will transmit on the channel/privacy
code on which you last received a transmission. This will return the radio to LISTENING MODE.

a. Press and hold the TALK button to communicate on either the channel or channel/privacy code that was displayed before you entered Mode
Functions or channel/privacy code on which, during scanning, you last received a transmission. This will return the radio to LISTENING MODE.
