EFJohnson High Tier, LTR 98xx manual Receive-Only Groups, Stealth Mode, Time-Out Timer

GENERAL FEATURES

Receive-Only Groups

Any group can be programmed for monitoring only (transmitting is disabled). If the PTT switch is pressed with one of these groups selected, the intercept tone sounds and “TX DSBL” is displayed.

Stealth Mode

The stealth mode disables the following tones and indicators so that they do not reveal that you are transmitting or otherwise indicate your presence. The speaker audio and display remain enabled in this mode.

All tones (see “Tone Select” on page 30)

The stealth mode can be selected by an option switch or the STEALTH menu parameter (see page 32), or is fixed in the on or off mode by programming. There is no special indication that this mode is selected except “On” is displayed under “STEALTH” in the menu mode.

Time-Out Timer

The time-out timer disables the transmitter if it is keyed continu- ously for longer than the programmed time. It can be programmed for 0.5

-5.0 minutes or disabled entirely. If the transmitter is keyed continuously for longer than the programmed time, the transmitter is disabled, “TIMEOUT” is indicated on the lower line of the display, and the inter- cept tone sounds. The timer and tone are reset by releasing the PTT switch. Ten seconds before time-out occurs, a beep sounds to indicate that time-out is approaching. There is also a timer that can be programmed to prevent transmitting for up to one minute after time-out occurs.

One use of the time-out timer feature is to prevent a repeater from being kept busy for an extended period by an accidentally keyed trans- mitter. It can also prevent possible damage to the transmitter caused by transmitting for an excessively long period.
