The USAlert WatchDog LT is a 2-Tone voice pager developed for use by fireman and other emergency personnel in the public safety markets. The LT can be used in any radio system that requires tone alerting and channel monitoring. Available in VHF (138 MHz to 174 MHz) or UHF (406 MHz to 512 MHz) frequency bands, the very loud and rugged WatchDog LT also features separate receiver boards designed specifically for narrowband or wideband operation. This makes the LT pager not only narrowband capable, but narrowband compliant.

The WatchDog LT is a simplified version of the original USAlert WatchDog voice pager. Along with being a more compact and lightweight option to the WatchDog, the LT also operates with a 4-position function switch. Each position can be individually programmed for the desired channel, alerting mode, monitoring mode, alerting type, and type of scan. The LT has 4 minutes of stored voice capability and retains the messages when the pager is powered off. The LT also holds a protection rating of IP66, which translates to protection against dust intrusion and powerful water jets from any direction.
