VX-6R/E OPERATING MANUAL68The VX-6R/E can display the radio’s inside-the-case temperature, measured by internalsensors. Also, when the optional Barometric Pressure unit (SU-1) is installed, you get theunique capability of providing readout of the current barometric pressure. This informationis then used for calculation of your current altitude.The Barometric Pressure unit requires calibration of the “offset” parameters, so that differ-ences in pressure can be used to calculate altitude. This procedure requires that you havea calculated barometer, and that you know your current altitude. If you are at sea level, ofcourse, the latter parameter requires no research.To display the Temperature1. Press the [F/W] key, then press the [0(SET)] key to enter the Set mode.2. Rotate the DIAL knob to select Set Mode Item 65: TEMP.3. Press the [0(SET)] key momentarily to indicate the current tem-perature inside the transceivre’s case.4. Press the [MODE(SP S)SQ TYP] key toselect the preferred unit (F (°F) or C (°C)).5. Press the PTT switch to exit to normal op-eration.To display the Sensor Information1. Press the [F/W] key, then press the [0(SET)] key to enter the Set mode.2. Rotate the DIAL knob to select Set Mode Item 64: SU1.SET.3. Press the [0(SET)] key momentarily to enable adjustment of thisSet Mode Item.4. Rotate the DIAL knob to select the sensor mode you wish to display.BARO: Indicates the Barometric Pressure on the frequency areaand relative changes in pressure on the S-meter area(requires optional SU-1). After 10 minutes, if the baro-metric pressure rises, the “8” and “9” segments of theS-meter will blink. If the pressure goes down, the “4”and “5” segments of the S-meter will blink.ALTI: Indicates the Altitude (requires optional SU-1).OFF: Disables display of the sensor information.5. Press the PTT switch to save the new setting and display thesensor information five seconds after releasing the PTT switch.6. When you operate the radio, the display willchange to show the frequency information,then resume the display of the sensor infor-mation after five seconds.7. To disable the display of sensor information, repeat the above procedure, rotating theDIAL knob to select “OFF” in step 4 above.SENSOR M ODEBAROMETRIC PRESSURE ALTITUDE
