H25T99FG Introduction The T99FG is a 200mW covert transmitter board, which may be installed in host devices such as the Motorola FLEX™ pager housing. The output power does not change over its operational battery life, unlike other covert transmitters due to a novel step-up switching power supply circuit. The transmission is a narrow-band FM signal, of 5 kHz deviation. The antenna is an internal loop antenna, tuned to the specific operating frequency.
H25T99FG All body-worn transmitters are susceptible to “clothing noise”. The holder that comes with the T99FG tends to keep the microphone away from the body, reducing this tendency. Flex™ Pager Features The Flex™ pager has several features that are fully functional and assist in the pager disguise. One useful feature is the clock display of the pager. Feel free to set the time and date on the display. But, if you do not, the clock will act as a timer indicating the time since turn on.
