The USAlert Alpha 4 Pager displays alphanumeric messages with a large 4-Line LCD and has zoom capability that will display larger characters in an easier to read 3-Line mode. 84 characters per screen are displayed in 4-Line mode and 48 characters per screen in the 3-Line mode. 60 messages can be stored in memory with each message capable of containing 500 characters. Maximum memory capacity is 30,000 characters. The fully synthesized Alpha 4 uses the POCSAG coding format, supports 9 languages, and is available in VHF, UHF, Midband, or 900 MHz frequency bands. There are 8 programmable capcode addresses and 32 sub-addresses, separate receiver boards for wideband and true narrowband operation, and alerting modes that include beep, vibrate, beep + vibrate, and mute. A single “AA” alkaline battery powers the pager and results in a typical battery life of about 60 days.
