4-1 Chapter 4 Transceiver Performance Testing For the missing sub-sections in this chapter, please refer to Basic Service Manual 68P80906Z54. 4.1 RF Test Mode When the radio is operating in its normal environment, the radioÕs microcontroller controls the RF channel selection, transmitter key-up, and receiver muting. However, when the unit is on the bench for testing, alignment, or repair, it is removed from its normal environment and cannot receive commands from its system. Therefore, the internal microcontroller does not key the transmitter or unmute the receiver. This prevents the use of a normal tuning procedure. To solve this problem, a special Òtest modeÓ is incorporated into the radio. Note 1: On UHF, LTR models, the radio must be in either conventional or LTR mode. Note 2: The test mode procedure that follows assumes that the Customer Programming Software Front Panel Access screen has both the FPA and RF TEST boxes selected. Select from the programming screen to enable or disable certain features of the radio RF test mode. lFPA entry not selected blocks all test modes. lFPA entry selected and RF TEST not selected blocks RF test mode. lFPA entry selected and RF TEST selected enables all test modes. To enter the test mode for a display radio: 1. Turn the radio on. 2. Within ten seconds after the self test is complete, press Ôside button 2Õ, shown in Figure 4-1, Þve times in succession. 3. After ÒCSQ CHXX SP25Ó appears on the display, the radio is on channel XX (see Note on following page), carrier squelch mode, 25 kHz channel spacing. Each additional press of Ôside button 2Õ (see Table 4-2) scrolls to the next channel spacing, and a corre- sponding set of tones are sounded. Refer to Figure 4-2 for test mode information for a two-line display radio. 4. Press Ôside button 1Õ to scroll through the test environments listed in Table 4-1 in Basic Service Manual 68P80906Z54. 5. Press Ôside button 2Õ for 3 seconds to switch the radio to the control head test mode. ÔLCD TestÕ appears on the display. 6. Press Ôside button 1Õ to turn on all the dots of the Þrst character. Another Ôside button 1Õ press turns on all the dots of the next character, continuing until the last character is reached. 7. Press Ôside button 1Õ at the end of the LCD test to activate the ÔIcon TestÕ. The next Ôside button 1Õ press turns on the Þrst icon. 8. Press Ôside button 1Õ at the end of the Icon Test to activate the button test. Pressing any side button (except Ôside button 1Õ), or any keypad button during the LCD test or Icon test immediately activates this test. A good button press is veriÞed by a chirp. 9. Press Ôside button 2Õ for 3 seconds in the control head test mode to return the radio to the RF Test mode.
4-2Transceiver Performance Testing To enter the test mode for a non-display radio: Button Test (For models with ÓGÓ in location 10 of model number Example: AAH25RCH 6GB6AN) 1. Press the orange button; Ò3/1Ó appears which indicates that switch 3 is in the closed condition. 2. Release the orange button; Ò3/0Ó appears which indicates that switch 3 is in the open condition. 3. Rotate the mode selector knob; Ò4/0Óthrough Ò4/15Ó appears which indicates that knob 4 is in mode position 1 through 15. 4. Rotate the volume control; Ò2/0Ó through Ò2/255Ó appears. 5. Press SB1, view Ò96/1Ó; release, view Ò96/0Ó. 6. Press SB2, view Ò97/1Ó; release, view Ò97/0Ó. 7. Press SB3, view Ò98/1Ó; release view Ò98/0Ó. 8. Press PTT button, view Ò1/1Ó; release view Ò1/0Ó.

Press Option Select1, view Ò135/1Ó; release, view Ò135/0Ó.10. Turn radio off to exit test mode. Note:XX = channel number (01 - 14) 1. Turn the radio on. 2. Within ten seconds after the self test is complete, press Ôside button 2Õ (Figure 4-1) Þve times in succession. 3. Press Ôside button 1Õ the number of times listed in Table 4-1 to get the number of corre- sponding beeps. 4. Turn radio off to exit test mode. 5. To access all 14 test modes on a 4-channel radio, the frequency knob and mechanical stop sleeve must be removed (see paragraph 3-8 exploded view diagram).
