2-20Service Aids 2.14 Test Equipment Table 2-2 lists test equipment required to service these and other two-way radios. † For those customers that need to test the LTR functioning of their radio instead of the R2600, purchase the HP8920 with LTR option. Please see your local Hewlett Packard representative for this item.NOTE While all of these items are available from Motorola, most are standard shop equipment items, and any equivalent item capable of the same performance may be substituted for the item listed.

3-1 Chapter 3 Transceiver Performance Testing 3.1 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. 3.2 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 Equipment Setup Diagram, Figure 4-4, on page 4-3. Initial equipment control settings should be as indicated in Table 3-1. The remaining tables in this chapter contain the following related technical data: Table 3-1: Table Chart Ta b l e N u m b e r T i t l e 3-2Initial Equipment Control Settings 3-3 Test Environments 3-4Test Channel Spacing 3-5 Test Frequencies 3-6Transmitter Performance Checks 3-7 Receiver Performance Checks
3-2Transceiver Performance Testing 3.3 RF Test Mode This test mode is for display radios only. When the radio is operating in its normal environment, the radio’s 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 “test mode” is incorporated into the radio. 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.Table 3-2: Initial Equipment Control Settings Service Monitor Test Set Power Supply Monitor Mode: Power MonitorSpkr set: AVoltage: 13.2Vdc RF Attn: -70 Spkr/load: Speaker DC On/Standby: Standby AM, CW, FM: FMPTT: OFF Volt Range: 10V Oscilloscope Source: Mod Oscilloscope Horiz: 10mSec/Div Oscilloscope Vert: 2.5kHz/Div Oscilloscope Trig: Auto Monitor Image: Hi Monitor BW: Nar Monitor Squelch: mid CW Monitor Vol: 1/4 CWCurrent: 2.5A Note: The test mode procedure that follows assumes that the Customer Programming Soft- ware front panel access (FPA) 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.
Transceiver Performance Testing3-3 To enter test mode: 1. Turn the radio on. 2. Within ten seconds after the self test is complete, press button P2, five times in succession. 3. After “CSQ CHXX SP25” 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 3-2. 6. Pressing P2 for three seconds switches the radio to the control head test mode. ‘LCD Test’ appears on the display. 7. Pressing P1 causes the radio to turn on all the dots of the first character. Another P1 press turns on all the dots of the next character and so on until the last character (character 14). 8. Pressing P1 at the end of the LCD test activates the ‘Icon Test’. The next P1 press turns on the first icon. 9. Pressing P1 at the end of the Icon 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. *XX = channel number (01 - 14)
