System Considerations - Motorola ASTRO XTL 5000 User Manual

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.
