This was made in 1998. Here is what was said about it then:
LS350
Motorola's new LS350 is designed for the first-time pager user who wants an entry-level "hip" pager to stay in touch with friends and family. This numeric pager, available with FLEX technology, offers many enhanced features, including: 30 message slots; the ability to save messages when changing the battery; a smart alarm; time and date on standby; selective erase; and three musical alerts. In addition, LS350 has silent vibration, message timestamping, the ability to lock messages and an easy-to-read backlit display.
It still works fine. It just takes one AA battery and it's good to go!
