ASTRO XTL 5000 Digital Mobile Radio with W4, W5, W7, and W9 95

Secure Operation

System Considerations

• Trunked Systems only: If you press the PTT button when no

secure-voice channel is available, the display shows NO SEC (W4,

W5, W7) or NO SECURE (W9), and a continuous talk-prohibit tone

sounds until you release the PTT button.

• Analog trunking systems: You are not allowed to change from

a secure transmission to a clear transmission during a secure

trunked call. If you attempt to change from a secure to a clear

transmission during a call, the radio generates a talk-prohibit tone,

and the display will show SEC ONLY or SECURE ONLY.

• Digital trunking systems: You are allowed to change from a

secure transmission to a clear transmission during a secure

trunked call.
