Transmit Timeout-
Timer
TOT [ON/OFF, 1-255]
The Transmit Timeout Timer limits the time a radio can remain contin-
uously keyed. If a radio remains keyed for longer than the timer dura-
tion, the transmitter automatically de-keys. The radio must transition to
the de-keyed state before accepting a new keying request.
The TOT command entered without a parameter displays the timer value
in seconds.
To enable the timer, enter TOT ON. To disable the timer, enter TOT OFF.
The default is TOT ON.
To set the timer value, enter the TOT command followed by a parameter
ranging from 1 to 255 (seconds). The default is 30 seconds.
Transmit Frequency TX [xxxx]
This command displays or changes the radio’s transmit frequency. Nor-
mally, the radio ships to the customer programmed with the cus-
tomer-specified frequency. If you did not specify the operating
frequency when the radio was ordered, the TX frequency is set to the
center of the radio’s operating band (see Section 2.6, Model Number
Codes, beginning on Page 6 for the model’s operating band).
If the transmit frequency is changed more than 100 kHz from the fac-
tory’s setting, review the duplexer guidelines in Section 8.4, Operating
Frequency Change Considerations, beginning on Page 89.
