INSTALLATION, COMMISSIONING & ALIGNMENT - Issue 1.0

Page 4-14 03/01

This completes the transmitter alignment

process.

4.5.6 Receiver Alignment

Audio Volume Level

a. Set the test set to the appropriate

frequency at –47dBm with 1kHz tone

modulation at 60% system deviation:

12.5kHz channel spacing 1.5kHz dev.

or 20kHz channel spacing2.4kHz dev.

or 25kHz channel spacing3kHz dev.

b. Select Channel 1.

c. With the calibration program running on

the PC, select Rx_Vol.

d. Turn the volume control to maximum.

e. Using the PageUp and PageDown keys,

press until the desired maximum volume

level is achieved.

Note: -17.5dB corresponds to 2.10V (+/-0.2V)

into 4 ohm speaker.

At maximum volume, nominal distortion is

10%.

f. Write the changes to the radio.

It may be necessary to carry out adjustment of

the squelch setting, see Section 4.5.4.

This completes the receiver alignment

process.

The following parameters would NOT normally

be adjusted unless specific environmental

conditions necessitate a change:

INTRIM on the receiver (Audio from IF IC.)

SATRIM on the receiver (gain received – sub

audible tone)

Refer to the ACC-2003 User Guide for details.
