TRANSCEIVER PERFORMANCE TESTING
1.0 General
These radios meet published specifications through their manufacturing process by utilizing high- 
accuracy laboratory-quality test equipment. The recommended field service equipment approaches 
the accuracy of the manufacturing equipment with few exceptions. This accuracy must be 
maintained in compliance with the manufacturer’s recommended calibration schedule.
2.0 Setup
Supply voltage is provided using a 13.2Vdc power supply. The equipment required for alignment 
procedures is connected as shown in the Radio Tuning Test Setup Diagram, Chapter 4, Figure 4-6.
Initial equipment control settings should be as indicated in Table 3-1. The remaining tables in this 
chapter contain the following related technical data:

							3-2TRANSCEIVER PERFORMANCE TESTING
3.0 RF Test Mode (5-Tone Radios)
When the radio is operating in its normal environment, it is not possible to test all individual aspects 
of the transmitter and receiver performance. Therefore a special “test mode” is used to allow the 
service technician to perform certain functional tests on the product. A control head fuctional test 
mode is also available.
To enter test mode (CM360):
1.Turn the radio on.
2.Within less than one second of the power-up beep, press button P2, five times in succession.
3.Six characters appear on the 8-character display, ‘TT XX CC’, where ‘TT’ indicates the test 
environment (Table 3.2), ‘XX’ indicates the channel number 1-14 (Table 3.4), and ‘CC’ 
indicates the channel spacing (Table 3.3). Test frequencies (channels) may be changed with 
use of the Up-Down button. Each additional press of P2will scroll through the remaining 
channel spacings supported.
4.Pressing P1 scrolls through and accesses test environments as shown in Table 3-2.
5.Pressing P2 for at least one second switches the radio to the control head test mode.  ‘LCD
Te s t’  appears on the display.
6.Pressing P1 causes the radio to turn on all segments of the first character. A second P1 press 
turns on all the segments of the second character and so on until all segments of all eight 
characters are illuminated.
7.Pressing P1 at the end of the LCD test activates the ‘Icon & LED Test’. The next P1 press 
turns on the first icon. Successive presses of P1 cycle through all icons and finally the three 
LEDs.
8.Pressing P1 at the end of the ‘Icon & LED Test’ activates the button test. When a button is 
pressed a single beep is heard and another beep on each release of all four P buttons plus 
the Up-Down button.
9.Pressing P2 for at least one second in the control head test mode causes the radio to return 
to the RF test mode.
Note:The radio powers up on the last used test state i.e. the last used test environment and 
channel spacing, but always starts at channel 1.
To enter test mode (CM340):
1.Turn the radio on.
2.Within less than one second of the power-up beep, press button P2, five times in succession.
3.The three LEDs will turn on and the single character segment display will indicate channel 1. 
As the display can only show 1 to 8, channels 1 to 7 are repeated with a dot on the display to 
indicate high power. Channels 1 to 7 with no dot represent low power (Table 3.4). An audio 
alert will sound to indicate the test environment. 
4.Pressing P1 will scroll through the other 12 test environments with its associated audio beep. 
(Table 3.2)
5.Press P2 to scroll through the three supported channel spacings channel spacings supported 
(Table 3.3)
6.Pressing P2 for at least one second switches radio to the control head test mode. A beep will 
sound and the segment goes blank.
7.Pressing P1 will cycle scroll through the segment test, then the LED test and finally the HI/LO 
power segment indicator; a high pitched beep will also sound as P1 is pressed.  
						

							RF Test Mode (5-Tone Radios)3-3
8.In this mode all buttons, when pressed and held, will emit a high pitched beep and another 
when the button is released to verify button functionality.
9.Pressing P2 for at least one second will return the user to RF Test Mode 
Note:The radio powers up on the last used test state i.e. the last used test environment, test 
channel, and channel spacing.

							RF Test Mode (MDC Radios)3-5
4.0 RF Test Mode (MDC Radios)
When the radio is operating in its normal environment, it is not possible to test all individual aspects 
of the transmitter and receiver performance. Therefore a special “test mode” is used to allow the 
service technician to perform certain functional tests on the product. A control head fuctional test 
mode is also available.
To enter test mode (display radios):
1.Turn the radio on.
2.Within ten seconds after the self test is complete, press button P2, five times in succession.
3.Channel number appears in the display. The radio is on channel XX*, carrier squelch mode, 
25 kHz channel spacing.
4.Each additional press of P2 scrolls through to the next channel spacing and a corresponding 
set of tones are sounded.
5.Pressing P1 scrolls through and accesses test environments as shown in Table 3-5.
6.Pressing P2 for three seconds switches the radio to the control head test mode and zero 
appears on the display.
7.Pressing P1 causes the radio to display the channel number “1”. Another P1 press causes the 
radio to display the next channel “2”, and so on until channel “9”.
8.Pressing P1 at the end of the LCD test activates the ‘LED Test’. The next P1 press turns the 
LEDs and dot On/Off.
9.Pressing P1 at the end of the LED test activates the button test. Pressing any button (except 
P1) or any keypad button during the LCD test or Icon test immediately activates this test.
10.Pressing P2 for 3 seconds in the control head test mode causes the radio to return to the RF 
test mode.
