Overview of the VNS Therapy System's patient magnets and Programming Wands. (A) Legacy block (Model 220-1) & horseshoe (Model 220-2) magnets (top) and watch-style (Model 220-3) magnet (bottom). Guass (Gs), or magnetic flux density is provided for each magnet. (B) M201 Programming Wand. Light indicators on the front signify normal, successful communication (yellow DATA/RCVD light) and a good battery level (green POWER light). Compatible with the M250 “Motion Tablet” Programmer (not shown). The M201 Wand is turned on by pressing two red “RESET” buttons simultaneously. (C) Programming Wand M2000. The Wand's power button signifies whether it is powered on (two green lights below power button), connected to the M3000 Programmer (four green lights around power button), or is updating (green lights rotate around power button, v1.1+). Icons on the front of the Wand also signify communication with the generator (white flashing generator icon) and battery status (orange battery indicator if low). The back of the M2000 Wand features a serial number that registers on the M3000 Programmer for identification purposes.
