    When the same conditions are encountered again, re-tuning is accomplished within 20 milliseconds by recalling the information from the non-volatile memory. Special software has been designed by SGC to allow accurate and fine-tuning of the coupler. For software description, refer to the MicroTune section of the manual.

    If you need to install the antenna coupler more than 50 feet from the transmitter site, up to two extension cables may be used for a total of 75 or 100 feet. However, SGC does not recommend installing the Smartuner more than 100 feet from the transmitter because two losses must be considered.

    3.3 Technical Support Before contacting SGC for technical support, please take a few minutes to think through your installation and ask if there is anything obvious that you have overlooked in the installation. Check to make sure your ground system is both adequate and tight and that proper voltage is supplied to the coupler.
