• radio coverage in marginal reception areas.
Lack of static noise
On digital networks there is no static noise, even in low signal areas. This lack of static is because the digital radio
removes the 'noise' from the call, so that only clear voice is audible.
Active Noise Cancellation
Active noise cancellation uses a secondary microphone on the back of the radio to actively filter out background noise
in loud environments. When safety features such as Loneworker Monitoring, Emergency Operation or Radio Unit Mon-
itor are activated, the listener may lose awareness of the noisy environment. Tait recommends users implement sup-
plementary procedures to account for this.
Coverage
With digital networks, a call remains clear and then drops off quickly at the border of a coverage area. The reason for
this is that a digital call is either received or it isn't. With analog networks, the background noise in a call gets pro-
gressively worse when the user is in fringe areas or even slightly outside normal coverage areas.
P25 phase 2 operation
This feature is controlled by a software license (SFE) and may not be available with your radio.
TP9600 radios can be programmed to operate on P25 trunked phase 2 networks. You will recognize that your radio
operates on a P25 phase 2 network if the RSSI indicator does not disappear while transmitting. This is because the
radio continues to receive data in the background.
If one participant of a call uses a P25 phase 1 radio, the call may be made as a P25 phase 1 call.

About the Radio Controls

The radio controls are the PTT key, power/volume control, channel selector , 3-way selector control, scroll keys,
selection keys, and function keys. Some keys have functions assigned to both short and long key presses:
• a short key press is less than 0.75 s, and
