Vertex Standard VXA-710

VXA-710 SPIRIT OPERATING MANUAL

MENU (“SET”) MODE

7. Bandwidth

Function: Selects the receiving bandwidth of the BRS

Memory Channel.

Available Values: Wide (±25 kHz)/Narrow (±12.5 kHz)

Default Setting: Wide (±25 kHz)

7. OPTION

1. Internal MIC

Function: Internal Microphone On/Off

Available Values: Off/On

Default Setting: Off

This controls the status of the radio’s internal microphone

when an external microphone (such as the MH-44A4B

Speaker Microphone or an aviation headset connected via

the CT-96 Headset Cable) is in use. In most applications,

set this Menu Item to “Off” for proper operation (this dis-

ables the internal microphone). The internal microphone

will still function normally when the external microphone

is disconnected.

2. TEMP Offset

Function: Correcting the Thermometer setting

Available Values: [–22.8 °F (–12.7 °C)] - [+22.8 °F (+12.7

°C)]

Default Setting: 0.0 °F (0.0 °C)

This allows you to calibrate the internal thermometer with

a known-to be-accurate source.

3. Clock Shift

Function: CPU Clock Shift

Available Values: Off/On

Default Setting: Off

This function is only used to move a spurious response

“birdie” should it fall on a desired frequency. Consult your

Vertex Standard dealer for details regarding this function.
