How to check your frequency setting
- Simply remove the cover from your wall mounted transmitter to check whether the 7K or 10K light is lit.
Boundary Plus transmitters: Push up on the front of the transmitter to reveal the settings panel.

Dual-Loop Boundary Plus transmitters: Push the plastic button on the bottom of the transmitter to remove the front cover.

ICT-801 transmitters: Push up on the tab at the bottom of the transmitter to remove the front cover. Some ICT-801 transmitters have the additional setting of “8xx” or “7xx”. If your system is set to “7xx”, then you need a 700 series collar instead.
