The DSAN PC-AS4-GRN is a pocket-size 4-Button Wireless Transmitter with a Green Laser for the PerfectCue presentation signaling system. It is compatible with all PerfectCue systems, including the PerfectCue Mini. It features three command buttons and a fourth button that turns on a bright green laser pointer. The three command buttons signal "Forward" (next slide), "Reverse" (previous slide), and "Blank Screen" commands to the PerfectCue. "Blank Screen" removes everything from the screen and puts the focus on you for times such as when you're finishing up your presentation. The first two buttons are designed with embossed dots providing for a tactile feel.

The PC-AS4-GRN operates at 433 MHz and reaches ranges of 300 ft or more even in noisy RF environments (although not the laser). You can select from 256 channels to transmit over. The desired channel is assignable via a dip switch under a cover door on the rear.

The transmitter is powered by two included CR2032 coin batteries, which last up to a year under normal use, and one CR123 battery that powers specifically the laser for approximately 25 hours of use.
