ASTRO XTL 1500 Digital Mobile Radio with Control Head 75

Secure Features

System Considerations

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

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

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

secure transmission to a clear transmission during a secure

trunked call.

Loss Indication

When you press the PTT button while in the coded mode and without

the encryption module containing a valid key, the speaker generates

bursts of alert tones, and the display shows KEY FAIL until you

release the PTT button.

When the radio is first turned on, six medium-pitched tones sound

and the display momentarily shows KEY FAIL to indicate that the

encryption module does not contain a valid key for the current mode.

If the periodic keyfail tone feature is enabled, six medium-pitched

tones are generated every five to ten seconds while the radio is not

transmitting or receiving to remind you that the radio does not have a

valid key for the current mode. The keyfail reminder will not sound

when the radio is in clear mode.
