Programming APCO 25 Systems To program an APCO 25 system, follow the steps in the appropriate section for conventional or Motorola Trunking. APCO 25 systems require only 1 additional setting: Sound Quality. Setting APCO 25 Sound Quality Each APCO 25 system has slightly different system settings that control how the audio is digitized. To get the best sound quality, you need to match as closely as possible the system's settings. To adjust the sound quality: 1. While monitoring a specific APCO P-25 talkgroup, press the HOLD/MAN key. 2. Press and hold the 9 key. On Line 1 of the screen you will see SOUND QULTY: 0050 (for example). This shows the Sound Quality. The lower the level the better the Sound Quality. 3. To manually set the sound quality, rotate the scroll bar up or down. As the threshold adjusts in increments of 100 at the bottom of the screen watch the Sound Quality level increase or decrease and continue to rotate the scroll bar until you have achieved the best Sound Quality level. Notes: • When APCO P-25 signal is not received, SOUND QULTY: **** appears on the display. • You must be receiving an APCO P-25 signal to make this adjustment A chart showing the Threshold Adjustment Range is listed below.
