PMR150March 19, 2009 Chapter 4 Performance Checks 4.1 General These radios meet published specifications through their manufacturing process by utilizing high- accuracy laboratory-quality test equipment. The recommended field service equipment is as accurate as the manufacturing equipment with few exceptions. This accuracy must be maintained in compliance with the manufacturer’s recommended calibration schedule. 4.2 Power-Up Self Test Applying power to the radio by using the on/off volume control, starts a self-test routine which checks the RAM, EEPROM hardware and EEPROM checksum. Pressing and holding SB1 while turning on the radio causes the self-test routine to check for the ROM checksum as well. If these checks are successfully completed, the radio will generate the Self-Test Pass Tone. If the self-test is not successful, a Self-Test Fail Tone is heard. Supply voltage can be connected from the battery eliminator. The equipment required for alignment procedures is connected as shown in the Radio Performance Checks Setup diagram (Figure 4-1).

March 19, 2009 PMR150 4-2Performance Checks: RF Test Mode Initial equipment control settings should be as indicated in Table 4-1 and should be the same for all performance checks and tuner alignment procedures. 4.3 RF Test Mode When the PR400 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. This mode allows bench testing of the radio at various test frequencies across the entire band, at both high and low transmit power (if applicable), at various channel spacings, and with different coded or carrier squelch types. Any customer specific programming in the radio will not be changed or affected by use of the RF Test Mode.. Figure 4-2. Side Button Locations Table 4-1.

PMR150March 19, 2009 Chapter 5 Radio Alignment Procedures 5.1 Introduction This chapter provides an overview of the Commercial Series Customer Programming Software (CPS) and the Global Tuner as designed for use in a Windows® 98/NT4/2000/ME/XP environment. Both cover all the functions of the traditional Radio Service Software (RSS) package. They are both available in the CPS and Global Tuner (CD ROM) Kit (RVN4191). 5.2 CPS Programming Setup Refer to online help files for the CPS Programming procedures. (See Figure 5-1 for CPS Programming Setup). Figure 5-1.

March 19, 2009PMR150 5-2Radio Alignment Procedures: Radio Tuning Setup 5.3 Radio Tuning Setup A Windows 98/NT4/2000/ME/XP PC (personal computer) and Global Tuner are required to tune the radio. To perform the tuning procedures, the radio must be connected to the PC, RIB (Radio Interface Box) and Universal Test Set as shown in Figure 5-2 below. Refer to online help files for the tuning procedures. Note: Radio Setup Requirement Ensure at least one Conventional Personality Channel is programmed on the radio for Global Tuner to function properly. Figure 5-2.
