calibrate the radio.
• First, measure the voltage of the lipo for the GT3C
• Install lipo, and turn on the radio
• After power up, the screen will display CAL for afew seconds, then turn to a screen where 6
menu items blink, a digit is displayed on the left, and 3 digits are displayed on the right
o The left digit should be “1”, this means CH.1 (st. wheel) is being calibrated

• Pull trigger to max, wait till numbers steady out, and press enter
• Push trigger to max, wait till numbers steady out, press enter
• Now channel 2 has been calibrated, rotate the enter wheel till 4 is displayed. This is to calibrate
the battery voltage
o “3” is not important at this time
• Once 4 is displayed, press enter. Rotate the enter wheel to the voltage that was measured before
power up. The press enter, now press and hold enter for about two seconds . This is called a
LONG-enter, which exits and saves the current menu that is open.
o After the LONG enter, the lower power alarm will be buzzing. This is normal, proceed to
