When damaged parts are replaced, identical parts should be used. If the identical replacement part is not locally available, check the parts list for the proper Motorola part number. Order parts from the nearest Motorola Communications parts center listed in Chapter 1, Introduction.
Dismantling Tool If a unit requires more complete testing or service than is customarily performed at the basic level, send the unit to a Motorola Authorized Service Center. (See Chapter 1, Introduction for a list of regional service centers.) The following disassembly procedures should be performed only if necessary.
Maintenance Dismantling Tool Figure 2-1: Typical Control Head Removal 3. Pull the control head away from the radio assembly as shown in Figure 2-2. Flexible Connection Figure 2-2: Flexible Connection Removal 4. Remove the flexible connection from the socket on the control head board. 2.6.2 Top Cover Removal 1.
Maintenance 3. Lift the top cover from the chassis. Dismantling Tool Figure 2-3: Top Cover Removal 2.6.3 Transceiver Board Removal 1. Remove six screws (nine for LowBand) from the diecast cover using the T20 TORX™ driver as shown in Figure 2-4. 2.
Maintenance 3. Slowly lift the transceiver board on the edge at the front of the radio (the edge that mates with the control head) and pull gently toward the front of the radio as shown in Figure 2-5. Take care to slide the antenna connector and power connector out of the chassis towards the front.
Maintenance device may have been over-stressed as well. Handle the transceiver board per the procedure for “Safe Handling of CMOS and LDMOS Devices”, Section 2.3. 2. If removing the transceiver board, the thermal pad material under the two Final stage devices (Q1402 and Q1403) on the radio chassis has been pulled up such that the radio chassis is exposed through the thermal pad, then the defective thermal pads must be removed and replaced.
Maintenance Figure 2-6: Control Head Back Housing Removal 2. Press the dismantling tool until the snap connectors on the side of the back housing release from the control head. 3. Disconnect the speaker socket. Figure 2-7: Control Head Board Knob Removal 4.

Radio Programming and Tuning Procedures Radio Tuning Setup A personal computer (PC), Windows 95/98/NT, and a tuner program are required to tune the radio. To perform the tuning procedures, the radio must be connected to the PC, radio interface box (RIB), and test equipment setup as shown in Figure 4-4.
Radio Programming and Tuning Procedures Transmitter Tuning The following sub-sections contain the procedures to tune the radio transmitter. These procedures include: Power Amplifier (PA) Bias Tuning Battery Threshold Tuning Reference Oscillator Warp DAC Tuning (LowBand radios only) Transmit Power Tuning Power Amplifier (PA) Voltage Limit Tuning (VHF 1-25W and UHF 1-25W LDMOS radios only) Modulation Balance Attenuation VCO Attenuation...

Radio Programming and Tuning Procedures 4.4.4 Transmit Power Tuning Note: 1. Tuning of the PA BIAS must be performed first. 2. DAC Tuning must be performed first (LowBand radios only). 3. IMPORTANT: To set the transmitter power for customer applications use the Cus- tomer Programming Software (CPS).
Radio Programming and Tuning Procedures 4.4.6 Modulation Balance Attenuation Note: 1. When using test box RLN4460B/C, inject the signal into the radio at the METER IN terminal and set the METER IN selector switch to “VOL”. 2. Tuning of the transmit power and reference oscillator warp must be performed first.
Radio Programming and Tuning Procedures 4.4.7 VCO Attenuation Note: 1. Tuning of the modulation balance must be accomplished first. The transmit devi- ation Limit softpot sets the maximum deviation of the carrier. Tuning is performed for 12.5 kHz, 20 kHz, and 25 kHz channel spacing. Tuning for 25 kHz channel must be done first for all frequency points.
4-10 Radio Programming and Tuning Procedures 4. Note the deviation obtained. 5. Adjust the slider, adjust the spin control or key in softpot values for the frequency point until the deviation is within the range as defined in the Table 4-6 on page 4-9. Press ENTER to confirm the selection.
Radio Programming and Tuning Procedures 4-11 4.4.11 DTMF Deviation Tuning This tuning option controls the dual-tone, multi-frequency (DTMF) deviation. Note: Modulation balancing and VCO attenuation must be performed prior to this tuning operation. Not doing so will result in the wrong deviation value being obtained while tuning the DTMF.
4-12 Radio Programming and Tuning Procedures 4.5.1 Front End Filter Tuning Note: 1. Tuning is normally not required. It should only be performed if a radio has poor sensitivity or pre-selector parts have been replaced. Radios are only tuned at one softpot frequency (See Table 4-7 through Table 4-12).

Select either Squelch Atten 12.5 kHz, Squelch Atten 20 kHz or Squelch Atten 25 kHz channel spacing variations. 2. Apply an RF signal modulated with a 1 kHz tone at 60% rated deviation listed in Table 4-16 for current frequency point (F1 being the first) of 10dB SINAD.

Chapter 5 Power Up Self-Test Error Codes - Conventional Radios Turning on the radio starts a self-test routine that checks the RAM, ROM checksum, EEPROM hardware, and EEPROM checksum. If these checks are successful, the radio generates two high- pitched self-test pass tones, or a musical tone (selected in CPS). If the self-test is not successful, one low-pitched tone is heard.
Power Up Self-Test CDM1550 PassPort Tone Options • In order to provide more detailed information about the radio’s state to a user or service technician various tones and display options are available. One Tone option is a short low pitched tone that sounds whenever the radio loses contact for any reason with its registered PassPort site and begins to search for another site.
Power Up Self-Test CDM1550 Special Diagnostic Functions • Some special diagnosis functions can be turned on "as needed" by accessing the "Service Menu". In order to enter this menu please proceed as follows 1) Press the Menu Key. (You don't need to be registered). 2) Quickly press the v then the w key.
