Foreword TSLRS
In this manual you will find guides to setup your system, tips to get most out of your system and how to
trouble shoot you problems. If you want to get a quick answer to your question you can go and see our FAQ
list, which contains all kind of questions we have received both simple and more technically oriented.
Foreword Transmitter
Here you will find the information which is needed to make your transmitter perform at the very best both
for Tx700Pro and for the Tx700Lite. Notice if the Pro or the Lite is not listed under a subject, it means that
it’s the same for both.
Technical Specs
Tx700Pro
RF Output power: 500mW/1000mW/2000mW.
RF Output connector: BNC female.
The transmitter power is user selectable via easy to access 3 way switch.
(We recommend using “low” power mode, so power up is possible in case of an out of range situation will occur)
The transmitter can handle full power, continually no time limit.

4
The antenna output is designed for 50 Ohm load; however the transmitter stage is specially protected and
can handle full power at both open and shorted antenna.
It is normal to perform range check with antenna removed and 500mW setting.
Tx700Lite
RF Output power: 500mW
RF Output connector: SMA female
RF Input: DIN 4
The Antenna output is designed for 50 Ohm load.
The PPM input signal can be either constant frame repeat time, or variable, Positive or Negative
polarisation. The special double speed Futaba PPM signal is also accepted, Auto detects and auto handle.
The main PPM signal must contain from 4-12 servo channels, if main PPM signal has under 4ch it will be
refused.
Note: Graupner call each way a servo travel for a channel, so in Graupner terms a 24 Channel setting
handle 12 servos, and is what we call a 12 channel signal.
