Privacy 

If enabled, this feature helps to prevent eavesdropping by unauthorized 

users on a channel by the use of a software based scrambling solution. 

The signaling and user identification portions of a transmission are not 

scrambled.
Your radio must have privacy enabled on the channel to send a privacy-

enabled transmission, although it is not required for receiving a privacy-

enabled transmission. Your radio supports two types of privacy:

•  Basic Privacy

•  Enhanced Privacy

Only ONE privacy type above can be assigned to your radio.
To unscramble a privacy-enabled call or data transmission, your radio must 

be programmed to have the same Privacy Key (for Basic Privacy), OR the 

same Key Value and Key ID (for Enhanced Privacy) as the transmitting radio.
If your radio receives a scrambled call that is of a different Privacy Key, OR a 

different Key Value and Key ID, you will either hear a garbled transmission 

(Basic Privacy) or nothing (Enhanced Privacy).
The LED lights up solid green while the radio is transmitting and blinks 

green rapidly when the radio is receiving an ongoing privacy-enabled 

transmission.
To make a private call:

1.  Press  [▲] or [▼] to navigate to Utilities and press [

VK

] to select.

2.  Press  [▲] or [▼] to navigate to Radio Settings and press [

VK

] to select.

3.  Press  [▲] or [▼] to navigate to Privacy and press [

VK

] to select.

4.  The display shows Privacy and Turn On. Press [

VK

] to enable privacy. 

The display shows Privacy On. If the Privacy was already on the 

display shows Privacy and Turn Off. Press [

VK

] to disable privacy. The 

display shows Privacy Off.

Note

: This feature is available only in digital mode.

Dual Tone Multi Frequency (DTMF) Analog

The Dual Tone Multi Frequency (DTMF) feature allows the radio to operate 

in a radio system with an interface to telephone or other DTMF based 

systems. DTMF Codes can be programmed into the radio by your RCA 

Communications Systems dealer. DTMF receive/transmit feature has four 

optional modes with 32 encode groups with up to 30 characters per group.
To use this feature, your radio must have an access code, which is system 

dependent. Please contact with your RCA Communications Systems dealer 

or system administrator for more information.
To initiate a DTMF call.

1.  Press and hold PTT button.

2.  Enter the desired number.

You can turn off the DTMF tone by disabling all radio tones and alerts.
