How far can the ACT-31D transmit?
In open air, the ACT-31D has a range of up to 200 feet. Walls, metal obstacles, and interference from other devices can reduce this effective range.

Check the battery voltage and replace it if necessary. Verify that the DIP switches match the receiver’s settings, and ensure the antenna is not damaged. If the problem persists, contact Linear technical support.
Can I use the ACT-31D for multiple gates?
The ACT-31D is a single-button transmitter, so it can control only one receiver or gate at a time. To operate multiple gates, you would need a multi-channel transmitter like the Linear ACT-34D or additional units.
How long does the battery last?
Under normal usage, the CR2032 battery should last 3 to 5 years. Rapid pressing or extreme temperatures may shorten the battery life.
Is the ACT-31D compatible with smartphone control?
