Vertex Standard VX-177 manual Transmitter TIME-OUT Timer TOT, Busy Channel LOCK-OUT Bclo

MISCELLANEOUS SETTINGS

TRANSMITTER TIME-OUT TIMER (TOT)

The TOT feature provides a safety switch which limits transmission time to a pre-pro- grammed value. This will promote battery conservation by not allowing you to make ex- cessively-long transmissions, and in the event of a stuck PTT switch (perhaps if the radio or a Speaker/Mic is wedged between car seats) it can prevent interference to other users as well as battery depletion. As configured at the factory the TOT feature is set to “6 min- utes,” and here is the procedure for activating it:

1. Press the [F] key, then press the [0(SET)] key to enter the Set mode.

2. Rotate the DIAL knob to select Set Mode Item 47: TOT. 3. Press the [F] key momentarily to enable adjustment of this Set

Mode Item. 4. Rotate the DIAL knob to set the Time-Out Timer to the desired

“Maximum TX” time (between 1 and 30 minutes), or OFF. 5. When you have made your selection, press the PTT switch to

save the new setting and exit to normal operation.

1)When your transmission time is within 10 seconds of the Time-Out Timer expiration, an Alert bell will provide an audible warning from the speaker.

2)Since brief transmissions are the mark of a good operator, try setting up your radio’s TOT feature for a maximum transmission time of one minute. This will significantly improve battery life, too!

BUSY CHANNEL LOCK-OUT (BCLO)

The BCLO feature prevents the radio’s transmitter from being activated if a signal strong enough to break through the “noise” squelch is present. On a frequency where stations using different CTCSS or DCS codes may be active, BCLO prevents you from disrupting their communications accidentally (because your radio may be muted by its own Tone Decoder). The default setting for the BCLO is OFF, and here is how to change that setting:

1. Press the [F] key, then press the [0(SET)] key to enter the Set mode.

2. Rotate the DIAL knob to select Set Mode Item 5: BCLO.

3. Press the [F] key momentarily to enable adjustment of this Set Mode Item.

4. Rotate the DIAL knob to set this Set Mode Item to “BCL. ON”

(thus activating the BCLO feature). 5. When you have made your selection, press the PTT switch to

save the new setting and exit to normal operation.
