MENU (“SET”) MODE

4. TEMP Unit

Function: Selects the measurement units for the Temperature sensor.

Available Values: °F/°C

Default Setting: °F

5. TEMP Check

Function: Enables/Disables the Over-Heating Alarm

Available Values: Off/On

Default Setting: Off

6. TEMP Set

Function: When the “TEMP Check” Menu item is set to “On,” and the temperature passes through the threshold set in this step, the BUSY/TX indicator will change col- ors, to alert you to the high temperature condition. The color of the “High Temperature” indication is set via the “TEMP LED” Menu setting (page 52).

Available Values: [32.0 °F (0 °C)] - [230.0 °F (110 °C)]

Default Setting: [122.0 °F (50 °C)]

NOTE: When the temperature reaches approximately 220 °F (105 °C), the radio will disable transmission, to allow the radio to cool off.

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-44A4BSpeaker Microphone or an aviation headset connected via the CT-96Headset Cable) is in use. In most applications, set this Menu Item to “Off” for proper operation (this disables 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.
