Motorola Astro Digital Mobile Radio Xtl5000 Basic 6881096c73 O Manual

							Chapter 5 Performance Checks
5.1 Introduction
This section covers performance checks used to verify that the radio meets published specifications. 
The recommended test equipment listed in the 
Chapter 4 approaches the accuracy of the 
manufacturing equipment, with a few exceptions. Accuracy of the equipment must be maintained in 
compliance with the manufacturer’s recommended calibration schedule.
5.2 Test Setup
The equipment required for XTL 5000 radio performance checks is connected as shown in the 
following diagram.

5-4Performance Checks: Test Mode
When in the transmit test mode, DTMF modulation produces a sidetone in the speaker. All signaling 
types will continually modulate the transmitted signal for detection/measurement by external 
instruments.
5.3.3 Control Head Test Mode
The control head test mode is part of the diagnostics built into the radio and is entered through the 
front panel programming sequence. This test mode allows you to perform button and display tests to 
verify proper operation.
1. Enter the control head test mode by pressing the Home button when the test mode menu,
 CH 
TEST
, is displayed. Use the Mode rocker to cause the radio to display the test mode menu, CH 
TEST
, if the display reads RF TEST.
2. Press the Mode switch to change the test mode from the RF test mode to the control head 
test mode (
CH TEST).
NOTE:Once the CH Test has been selected by pressing Home, pressing the Mode switch 
will not change the control head test mode back to the RF test mode. You must turn 
the radio off and reenter the RF test mode as described earlier.
3. When the control head test mode is selected (
CH TEST), press the Home button. The display 
will show the interpreted key number. Status of the key press is indicated to the right of the 
key number.

							Chapter 6 Radio Alignment Procedures
6.1 Introduction
This section describes both receiver and transmitter radio alignment procedures.
6.2 ASTRO XTL 5000 Tuner Software
A personal computer (PC) and Tuner Software are required to align the radio. Please refer to the 
CPS Programming Installation Guide (Motorola part number 6881095C44) for installation and setup 
procedures for the software. To perform the alignment procedures, the radio must be connected to 
the computer and to a universal test set, as shown in the following figure.
Figure 6-1.  Radio Alignment Test Setup
Select Tuner from the Start menu. To read the radio, use the File 
➝ Read Device menu or click on 
. Figure 6-2 on page 6-2 illustrates how the alignment screens are organized. To access a 
screen, double-click on the desired screen name in the Tuner menu. These procedures should only be attempted by qualified 
service personnel. Failure to perform alignment procedures 
properly may result in seriously degraded radio or system 
performance.

For dash-mount applications, the program/flash cable (HKN6155)
is connected to the microphone port on the control head.
For remote-mount applications, the program/flash cable is connected
to the FLASHport connector on the front face of the radio (P506).
Do not attempt to use a microphone while the cable is connected. **

6-2Radio Alignment Procedures: ASTRO XTL 5000 Tuner Software
Figure 6-2.  Tuner Main Menu
The alignment screens utilize the “softpot,” an analog SOFTware-controlled POTentiometer used for 
adjusting all transceiver alignment controls.
Each alignment screen provides the ability to increase or decrease the softpot value by using the 
slider or the spin buttons (
▲ and ▼), or by entering the new value from the keyboard. A graphical 
scale on the display indicates the minimum, maximum, and proposed value of the softpot.Do NOT switch radios in the middle of any alignment 
procedure. Always left-click the Close button on the screen to 
return to the Tuner Main Menu screen before disconnecting 
the radio. Improper exits from the Alignment screens may 
leave the radio in an improperly configured state and result in 
seriously degraded radio or system performance.
