General Radio Features
Time-Out Timer
The new ASTRO portable radio is equipped with a programmable time-out timer which, upon expiration, will turn off the transmitter. This timer is programmable through radio service software and can be set from 0 seconds (off) to 7.75 minutes (465 seconds), at 15 second increments. The ASTRO radios have been programmed at shipment for 60 seconds.
1.A time-out timer warning occurs approximately four seconds before the allocated time-out timer expires. The warning is a short, low-pitched tone.
2.If the PTT Switch is held down longer than the time-out timer’s allotted time, a continuous, low-pitched tone will sound and the LED will stop lighting red, indicating that your transmission has been cut off. This tone will continue to sound until the PTT Switch is released.
3.Release the PTT Switch.
4.To transmit another message, press the PTT Switch.
Low-Battery Indication
If the battery voltage falls below the low-voltage level, a short, high-pitched chirping tone (low-battery chirp) will sound.
Once a low-battery indication occurs, replace the battery.
Programmable battery status options include:
•When the PTT Switch is pressed, the bicolor LED will blink red to indicate a low-battery condition.
•When the PTT Switch is released following a transmission, a short, high- pitched tone (chirp) will sound to indicate a low-battery condition.
•When the radio is in the standby mode and a low-battery condition occurs, an alert tone will sound from 30 to 930 seconds (programmable through radio service software) at 30 second increments.
