ICOtec has halted the manufacturing of the original GC500 remote controls and are substituting your replacement remote with the GEN2 GC500 remote control.
The remote will sync and pair with your older model GC500. You will notice a few changes from your original version such as the new larger font, light switch, 2 FAV buttons, stand timer and a pause button. All features will function normally except for the PAUSE button, that will not operate on a GC500 call.
*ALWAYS use new batteries from the store, not from a drawer. ALWAYS test your batteries prior to leaving the house, and ALWAYS take spare batteries with you hunting.
