The TPL Birdy Slim is a thin, lightweight and exceptionally durable Alphanumeric Pager. Functioning as a POCSAG paging receiver, the Birdy Slim also has a built-in POCSAG paging transmitter. Included with each pager are a desktop charger, a rechargeable 3.7 V 700 ma Li-Ion battery, a belt clip and lanyard.
The TPL Birdy Slim Programmer package contains a cradle that is a combination of a programmer and charger, Birdy programming software, and a micro-USB to USB programming cable. The programming cradle is very similar in appearance to the Birdy Slim Charger cradle. The main difference between the two is the LED strip light of the programmer and charger cradle is green while the charger-only cradle LED strip light is blue.
