Calibrating Voltage and Setting the Battery Warning

Before setting the transmitter battery warning you need to calibrate the voltage reading. Measure the voltage of your battery with a voltmeter while the radio is on and then go to the calibration page. A long press of the LEFT key will take you from the home pages to a sequence of eleven radio setup pages. Use LEFT or RIGHT to get to 8/11:

At the bottom of the page opposite A8 is the transmitter voltage reading. Use the DOWN key to scroll to it. Press MENU to allow changes. The LEFT and RIGHT keys will adjust the voltage to agree with the voltmeter. Press MENU again when finished and EXIT to leave the item.

Now set the Battery Warning on page 1/11:

Use UP to go to the top of the page and then LEFT to go to page 1/11. Select Battery Warning. Use the LEFT and RIGHT keys to set the voltage to suit your battery, as recommended above.

Resetting the Battery Capacity Reading

From the home pages a long press of the UP key brings up a page where the battery details, time and a number related to CPU temperature are shown. In particular, the battery capacity used in milliampere-hours (mAh) since last reset is shown:

To reset the mAh reading to zero after charging the battery press the MENU key. This will allow you at any time to see how much capacity you have used from the battery since you charged it. The mAh capacity reading is based on the current value, which is accurate within about 10%.

Setting the Capacity Alarm

You may set an alarm to warn you of low remaining battery capacity on the Radio Setup page 2.

Select a number in mAh that is no more than 80% of the battery capacity. When the battery capacity used reaches this value an alert message will be announced. If the field is left at 0 no alarm will be announced. You have to remember to reset the battery capacity after recharging the battery.
