Privacy Codes

•

Your microTALK radio incorporates two advanced coded squelch systems that can help to reduce interference from other users on any given channel. CTCSS (Continuous Tone Coded Squelch System) provides 38 privacy codes and DCS (Digitally Coded Squelch) provides 83 privacy codes. This provides a total of 121 Privacy Codes. Either system can be used on all channels, but both systems cannot be used on the same channel at the same time.

To successfully communicate using a privacy code, both the sending and receiving radios must be tuned to the same channel and to the same privacy code system (CTCSS or DCS) and privacy code number. Each channel will remember the last privacy code system and number you select.

The privacy code 00 is not a privacy code, but allows all signals to be heard on a channel that is set to 00 on both the CTCSS and DCS systems.

2.Press using the Channel Up or Channel Down button to select a CTCSS privacy code. You can hold the Up or Down button for fast advance.

3.When your desired CTCSS privacy code is displayed, choose one of the following:

a.Press the Mode button to enter the new setting and proceed to other functions.

b.Press the Lock/Enter button to enter the new setting and return to Standby mode.

c.Do not press any buttons for 15 seconds to enter the new setting and return to Standby mode.
