Motorola Gr300 Zr310 Community Repeater 6880902z68 C Manual

 
Section 4 
Theory of Operation 
TPL Encoding  
Two signals are used for TPL generation: 
• Clock frequency at the exact TPL rate from the microprocessor  
• Clock frequency at 64 times the TPL rate from the timer module  
These signals are fed into a switched capacitor low pass filer U17, then sent to the transmitter.
 
DPL Encoding 
For generating DPL signals, the microprocessor sends the digital code out its pin 9. Data inversion is done inside the microprocessor if 
required. The timer module...

NOTE 
In order to have enough room to move the fan 
assembly around and to remove the ZR310, you will 
have to cut the cable tie wrap. Make sure that you 
obtain another cable tie wrap for use when 
reassembling the GR300.
 
4. Using a T25 torx screwdriver, remove the two M5x0.8x8 machine screws that secure the ZR310 to the repeater housing. 
5. Remove the ZR310 from the repeater housing. 
6. Disconnect the transmit and receive radio repeater cables from the transmit and...

 
Section 6 
Programming 
Overview 
This section contains information and procedures that allow the technician to program the ZR310. 
You can program the ZR310 in the following ways: 
• Motorola RIB compatible interface, using a computer running Motorola radio service software (RSS) designed for the ZR310  
• DTMF over the radio channel (over-the-air) from a mobile, base station, or handheld  
• DTMF from a telephone plugged into the programming jack on the front of the ZR310  
• ZR310 monitor program...

To allow all programming information to reset to default settings: 
1. Press F2 to continue. 
CAUTION 
To keep custom programming, you must use radio 
mode. If custom settings have previously been 
programmed for the radio, you will see the screen in 
Figure 6-6. Programming in repeater mode resets all 
custom accessor y information to its default settings. 
Pressing F2 (Continue) will overwrite any custom 
programming.
