To prevent overheating the RF PA during rework, use a ChipMaster (R1319 or R1321) top-side pre-heat set point of 215°C and a Dragon (R1427) bottom-side pre-heat set point of 204°C for 1 minute before and throughout top-side heat application, assuming that the RF PA is removed from the applied heat 10 seconds after reflow occurs. (The RF PA temperature does not reach the ChipMaster’s internal set point temperature). All other parts on the transceiver board can be reworked with ChipMaster top-side heat alone.Table 3-2.

November 11, 20046881094C12-A 3-6Test Equipment and Service Aids: Field Programming 3.4 Field Programming This family of radios can be aligned and programmed in the field. This requires specific equipment and special instructions. Refer to the Customer Programming Software (CPS) Installation Guide (Motorola publication part number 6881095C44) for information on installing the CPS, and to the on- line help in the CPS for complete field programming information. Refer to Figure 2-9 on page 2-29 for the accessory connector pinout.
Chapter 4 Performance Checks This chapter covers performance checks used to ensure that the SSE 5000 radio meets published specifications. The recommended test equipment listed in the previous section approaches the accuracy of the manufacturing equipment, with a few exceptions. Accuracy of the test equipment must be maintained in compliance with the manufacturer’s recommended calibration schedule. Checks should be performed if radio performance degradation is suspected. 4.1 Test Equipment Setup Supply voltage can be connected from the battery eliminator. The equipment required for the performance checks is connected as shown in Figure 4-1. Figure 4-1. Performance Checks Test Setup Initial equipment control settings should be as indicated in Table 4-1 and should be the same for all performance checks and alignment procedures, except as noted.

November 11, 20046881094C12-A 4-2Performance Checks: Radio Test Mode 4.2 Radio Test Mode This section provides instructions for performing tests in display radio test mode. 4.2.1 Access the Test Mode To enter the display radio test mode: 1. Turn the radio on. 2. Within 10 seconds of turning the radio on, press the one-dot side button five times in succession. The radio shows a series of displays that give information regarding various version numbers and subscriber specific information. The displays are described in Table 4-2. NOTE:When you turn the radio on normally, the radio performs a limited self-test. To allow the radio to perform a full self-test, press and hold the top side button while turning the radio on. If the self-test is successful, you hear a chirp. If the self-test is unsuccessful, you hear a single, low- frequency tone and see an error code on the radio’s display. See Table 8-2 on page 8-2 for the power-up error codes.Table 4-1.

If information is longer than the physical length of the radio’s display, the information will wrap around to the next display. 3. Do one of the following: •Press the green button on the control top to stop the displays and enter the RF test mode. The test mode menu option “1 CSQ” is displayed, indicating test frequency 1 , Carrier SQ uelch mode. See Section 4.2.2: “RF Test Mode” on page 4-4. OR • Press the top side button to stop the displays and select the control top test mode. The test mode menu option “CH TEST” is displayed, indicating that you have selected the control top test mode. See Section 4.2.3: “Control Top Test Mode” on page 4-5. NOTE:Each press of the top side button toggles between “CH TEST” and “RF TEST”. Table 4-2. Test-Mode Displays DisplayDescriptionAppears SERVICE The radio has entered test mode.

November 11, 20046881094C12-A 4-4Performance Checks: Radio Test Mode NOTE:Once your radio is in a particular test mode, you must turn off the radio and turn it back on again to access the other test mode. 4.2.2 RF Test Mode When the SSE 5000 radio is operating in its normal environment, the radios microcomputer controls the RF channel selection, transmitter key-up, and receiver muting, according to the customer codeplug configuration. However, when the unit is on the bench for testing, alignment, or repair, it must be removed from its normal environment using a special routine, called RF test mode. While in RF test mode: • Each press of the one-dot side button advances to the next test channel. (Refer to Table 4-3.) • Each press of the two-dot side button scrolls through and accesses the test environments shown in Table 4-4. Transmit into a load when keying a radio under test. Table 4-3.
