ASTRO XTL 1500 Digital Mobile Radio with Control Head 21

Basic Radio Operation

Time-Out Timer

This feature limits the amount of time you can continuously transmit.

Your system manager can program the timer for up to 465 seconds at

15-second intervals. XTL 1500 radios are programmed at the factory

to time-out after 60 seconds.

Notes: You hear a low-pitched alert tone four seconds before your

transmission is about to expire.

If you hold down the PTT button longer than the programmed

time, you hear a continuous, low-pitched tone. This tone

ceases to sound when you release the PTT button.
