Congratulations on your purchase of the WS4938, DSC’s wireless

from any location within the range of the alarm system. Signals

The button is small and lightweight enough to be placed in a shirt
pocket or tucked away inside purse. It can also be used with the
supplied neck strap or multi-functional clip, which can connect to
your belt, car visor or permanently mounted to a convenient location.
To activate, press and hold the key for approximately 2 seconds.
The LED located on the top of the unit will light up to confirm a
signal has been set.
Note: Signals will not be received if the key is not within range of the wireless receiver.
