The charger has a distinctive blue LED strip light and a rear-panel contact relay port for controlling external devices. An optional device combines both desktop charger and Birdy Slim programmer into one unit. This device can be identified by its green LED strip light indicator and also has the rear-panel contact relay port.
Birdy Slim models are available in the VHF, UHF or 900 MHz frequency bands and are operational in narrowband and wideband systems. The ruggedly designed pager holds an IP 67 protection rating meaning it has complete protection from dust intrusion and can withstand water intrusion for 30 minutes at a depth of 1 meter. The size of the pager is 3.8 x 2.2 x 0.7 inches (97.4 x 54.7 x 16.7 mm) and it weighs 3 ounces (90 grams).

The LCD has auto screen rotation capability and a programmable Multi-Color Backlight feature. 128 capcodes are available on the Birdy Slim, each capcode having 4 sub-addresses. These sub-addresses can be programmed with different Backlight colors to give a visual indication of the capcode and sub-address being alerted.
There are several pager settings that can be changed from the LCD user interface. These include receiver frequency and baud rate as well as transmitter frequency, baud rate, and the recipient capcode and sub-address.
A message alert tune can be selected through the user interface from any of the Birdy Slim's 21 Alert Melodies.

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.
The TPL Birdy Slim Desktop Charger is a standard item included along with a 3.7 VDC, 700 ma Lithium-Ion rechargeable battery in every Birdy Slim Pager package. A blue LED light strip located on the front base of the Desktop Charger indicates the unit is powered on.
The TPL Birdy Slim Rechargeable Battery is the main supplier of power for each Birdy Slim pager. The lightweight 3.7 VDC, 700 mA Lithium-Ion (Li-Ion) battery is one of the more popular types of rechargeable batteries used in small electronic devices.
The TPL Birdy Slim Alphanumeric Pager Belt Clip is a detachable accessory for the Birdy Slim pager that is made of the same durable material as the housing. Although the belt clip is included with each Birdy Slim pager, it can be removed if an alternative leather or textile carrying case is preferred. A replacement belt clip can be ordered if ever lost or damaged.
