Toggling The Display Mode; Optimizing P25 Performance - Uniden Trunk Tracker IV BCD996T User Manual

To get a visual indication of the activity on trunking systems, press [HOLD/RESUME] to hold on any channel. Then tap the Scroll
Control and then press [.No] The scanner replaces the third line on the display with trunking activity indicators. When the scanner is
monitoring on EDACS or Motorola system, the activity indicators will show which system frequencies have activity.
Note: for Motorola systems you must program all system frequencies (control and voice frequencies) for this feature to work.

Toggling the Display Mode

To change the display so the channel and frequency or Talk Group ID appear instead of extended channel information, hold on any
channel then press [FUNC] + [0]. The scanner displays Display Mode 2. To return to Mode 1, press [FUNC] + [0]
Mode1 indicates the channel data under the Channel Name.
Mode2 indicates the frequencies under the Channel Name.

Optimizing P25 Performance

You can optimize the scanner's performance with digital APCO 25 systems. Follow these steps for each system where you can hear
APCO 25 traffic.
Notes:
These steps work only when you can clearly receive the system. If you are in a weak-signal area or receive interference, these
steps will not work. These steps do not compensate for weak signals or signals subject to interference.
If you set an incorrect decode threshold level in Step 5, the scanner might stop decoding all digital signals in the system. If this
happens, change the setting to a value between 8 and 12 then repeat these steps.
