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 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 VFO 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.

		Lower		Mid		Upper
Band	Min	Default	Max	Default	Min	Default	Max
800MHz	33	533	1833	1985	2042	3342	3842
UHF	33	633	1833	1985	2042	3342	3842
VHF	330	930	2130	2147	2264	3464	4064

4.Once you have adjusted the Sound Quality to the best possible level, press E. Press RSM to exit the Sound Quality Adjustment Mode.

Notes: •	To cancel the adjusted threshold level, press		.	key.
•	The adjusted threshold level for the current frequency can be set back to the
	default value by pressing and holding the	.	key.

•When you change the Sound Quality it affects all other APCO 25 signals in that same band. (UHF, VHF, or 800MHz).
