This tiny and high resolution graphic display shows RSSI level and battery levels of your plane on your transmitter.

It is completely plug and play display, just plug on your FrSky Tx module's telemetry socket. No calibration or configuration required  for FrSky receivers that have external AN1+AN2 inputs.

It's coming with one free voltage sensor for your receiver. 

Just connect it between your D8R receiver and the battery for following your battery level on the ground. And you can buy extra voltage sensor for your second battery.

Configuring LCD Telemetry display for Internal AN1 ported FrSky V2 receivers 

FrSky producing some receivers with Internal AN1 port. Their internal voltage sensor's divider rate (1/4) is different from our voltage sensors (1/11) and this is why you should configure your LCD for this kind of receivers.

• Press and hold the button(BTN) of LCD before power on your transmitter.
• Power On your transmitter and keep holding the button

you will see the divider rate after startup screen like "11". this mean LCD calculating the voltage from 1/11 divider. It is default value of our voltage sensors.

• release the button
• press and release the button few times for "4" on the screen. Because the FrSky V2 receiver's internal AN1 divider's rate is 1/4
• Power Off your transmitter and on again.
• Done. LCD display recorded the divider rate and now it's calculating the first voltage from 1/4 rate internal divider.
