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 Whenever the radio is turn on, it initiates a self-test routine which checks the RAM, EEPROM hardware and EEPROM checksum. If Self Test passes, the green LED flashes once and a Self-Test Pass Tone is generated. If unsuccessful, the red LED flashes rapidly and a Self-Test Fail Tone is heard. 4.3 LCD/LED/Button/Volume Knob Test Mode 1.Make sure the radio is turned off. 2.Turn on the radio and immediately press 3 times. The LED turns solid amber. The LCD displays the following indication (Figure 4-1) and the backlight is activated. 3.The radio will operate as shown in Table 4-1 if any key is pressed while in test mode. Figure 4-1.

Chapter 5 Radio Programming and Tuning 5.1 Introduction This chapter provides an overview of the CP185 Series Customer Programming Software (CPS) and the CP/EP/P Tuner as designed for use in a Windows® 2000/XP/Vista environment. Both cover all the functions of the traditional Radio Service Software (RSS) package. They are both available in the CP185 Series CPS and Tuner CD-ROM (RVN5194_). 5.2 CPS Programming Setup Refer to online help files for the CPS Programming procedures. (See Figure 5-1. CPS Programming Setup for CPS Programming Setup). 5.3 Radio-to-Radio Cloning 1.Cloning is the process of copying the content of one radio (source radio) into another radio (destination radio). Radio content refers to system-type features such as frequency, squelch type option, etc. 2.The cloning can be done only if all the following conditions are met: a. The source radios serial number cannot be blank. b. The source radio and the destination radio must have the same model number. c. The source radio and the destination radio must have an identical major codeplug version. 3.Radio functionality inherent in one radio cannot be cloned to another radio that does not contain the same functionality. Tuning and alignment information are not transferable and are not affected by cloning.Figure 5-1.

5-2Radio Programming and Tuning: Radio Tuning Setup Procedure: 1.Turn source and destination radios off. 2.Connect cloning cable (PMDN4076_R) to programming port of the two radios. 3.Turn on the destination radio. 4.Press and hold on the source radio and power up. MASTER and programming mode icon are displayed on the source radio and at the same time LED of the radio turns solid amber. 5.SLAVE and programming mode icon are displayed on the destination radio and at the same time LED of the radio turns solid amber. 6.During the cloning process, LED flashes in amber and source radio displays CLONING while destination radio displays PROG ON. 7.When cloning is completed, the source and destination radios display COMPLETE. To exit cloning mode, radios should be turn off. 8.Turn both radios off. 9.Disconnect the cloning cable from both radios and turn them on for normal operation. 5.4 Radio Tuning Setup A Windows 2000/XP/Vista PC (personal computer) and Entry Level Radio Tuner are required to tune the radio. To perform the tuning procedures, the radio must be connected to the PC, Test box and Universal Test Set as shown in Figure 5-4 below. Refer to online help files for the tuning procedures.

There are separate alignment procedures for High and Low power. Note: When checking the RF power output of the radio with a test set, always use a pad of at least 30 dB attached to the radio end of the RF cable. This will avoid an RF mismatch and ensure a stable RF reading that will not change with varying lengths of connecting cable. Table 5-2.

5-4Radio Programming and Tuning: Transmitter Alignment Options 5.5.1 Transmit High Power Tuning 1.Click the Read icon to initiate communication with the radio. 2.Under the Alignment menu, select Tx Power, then select High (Figure 5-3. Tx High Power Window (High Power)). 3.Press PTT Toggle. This will key up the radio at the 1st test frequency (F1). 4.Read the Transmit Power from the Service Monitor. 5.Adjust the High Power Level as shown in Table 5-2 on page 3 by using either the Left/Right arrows on the slider or Up/Down arrows on the Working Softpot box. 6.Press PTT Toggle to dekey the radio. 7.Goto the next frequency point by clicking on the Working Softpot value and press PTT Toggle. 8.Repeat steps 4–6 for the remaining test frequencies (F2–F5). 9.Press Program to commit the softpot values into the codeplug. 10.Exit the Transmit High Power function. 11.If the radio uses only high power channels, proceed to adjust modulation. If low power channels are used, perform Transmit Low Power Tuning as defined. Figure 5-3. Tx High Power Window (High Power)
