Soft-Carrier

De-key Delay

This screen is used to set or display the Soft-Carrier Dekey Delay. This is the

amount of time to wait after a de-key request before actually de-keying the radio.

When the delay is 0, the radio will de-key immediately following removal of a keying

signal.

To change the delay, press ENTER, then use the left/right arrow buttons to select

the digit to change. Then use the up/down arrow buttons to increase or decrease

the digit. Repeat for the other digits if necessary. Press ENTER again to make the

change.

Transmit Timeout This screen is used to display the Transmit Timeout setting, and to enable or

disable this timer. When this timer is enabled, it disables the transmitter after a set

period of time to prevent unnecessary use of the frequency. If the radio is set to

continuous keying (see “Continuous Keying” on Page 68), the Transmit Timeout

Timer is automatically disabled.

To enable or disable the timer, press ENTER, then use the up/down arrow buttons

to display ENABLED or DISABLED. Press ENTER to make the change.

See the following command to change the timer delay.

Duration

To change the duration, press ENTER, then use the left/right arrow buttons to

select the digit to change. Then use the up/down arrow buttons to increase or

decrease the digit. Repeat for the other digit if necessary. Press ENTER again to

make the change.

RX Timeout

[NONE, 1-1440]

This screen is used to set or display the RX Timeout Timer duration. This is the

amount of time to wait (in minutes) after the last data receipt before switching over

to the stand-by transceiver board and generating an alarm.

To change the duration, press ENTER, then use the left/right arrow buttons to

select the digit to change. Then use the up/down arrow buttons to increase or

decrease the digit. Repeat for the other digit if necessary. Press ENTER again to

make the change.

To disable the Receive Timeout Timer, set the duration to NONE.

Repeater Mode This screen is used to set or display the radio’s operation as a repeater. When the

radio is set to operate as a repeater, the screen displays “enabled” (repeater mode

is enabled). When the radio is a non-repeater, the screen displays “disabled”

(repeater mode is disabled).

To change the operating mode, press ENTER, then use the up/down arrow buttons

to select ENABLE (repeater mode) or DISABLE (non-repeater mode). Press
