For example, both icons will show in the display when the transmitter is set to vibrate and beep to indicate a status change. When there is no notification of a status change, neither icon will show in the display (see page 23). HiFi Microphone HiFi Microphone User Guide WGD00181, Revision A 29 HiFi Microphone Synchronizing the Transmitter and the Base The transmitter and the base in the vehicle must be synchronized before the DVR can record audio transmitted by the transmitter's microphone. The pairing that is created when the transmitter and the base sync together, which lets them identify each other's communication. For information on the transmitter, see page 20. For information on the base in the vehicle, see page 16. Mics that stay in the same vehicle from shift to shift remain synchronized with the base in that vehicle. If you move your transmitter between vehicles or take it from a pool of mics inside the agency, you must sync the transmitter with the base in the vehicle before you can use it. Note: A charge-only version of the base is available for the HiFi Microphone (HiFi Mic). Charge-only bases are not used in vehicles. For information about charge-only bases, contact your Motorola Solutions representative. The transmitter and the base in the vehicle sync automatically when you place the transmitter in the powered base for a few seconds. To sync the transmitter with the base:

1. Power the DVR on and verify it is ready to use. 2. Power the transmitter on (see page 25). 3. Place the transmitter into the base. The LEDs on the transmitter and the base flash and the transmitter beeps as the pair syncs. After the transmitter and base are synced, either the green LEDs turn on (the transmitter is ready to use) or the red LEDs start flashing (the transmitter needs charging). 4. Remove the transmitter from the base and verify the connection on the transmitter's display (see page 27). For information on charging the transmitter, see page 31. 30 HiFi Microphone HiFi Microphone User Guide WGD00181, Revision A Charging the Transmitter Charging the Transmitter The battery in the transmitter must be charged before you can use the HiFi Microphone (HiFi Mic). The base (either the vehicle base or the charge-only base) serves as the charger for the transmitter. Important! Avoid touching the charge and sync contacts on the base and transmitter with your bare hands. To charge the transmitter:

1. Power off the transmitter (see page 25). 2. Place the transmitter in a base. Note: Motorola Solutions recommends that you power off the transmitter before you put it in the base to charge, but this step is not required. If the base is in the vehicle, the base syncs with the transmitter before the transmitter begins to charge. For more information about syncing the transmitter and the base, see page 30. With charge-only bases, mics begin to charge immediately. Charge-only bases are usually used in an office environment. Note: A charge-only base serves only as a charger for the HiFi Mic and is not used in a vehicle. For information about the charge-only base, contact your Motorola Solutions representative. As the transmitter charges, the red LEDs flash and the bars in the Battery Level icon on the display cycle in series. When the transmitter is fully charged, the green LEDs illuminate, and the Battery Level icon shows four bars (see page 27). After 65 minutes in a base, the transmitter is approximately 50 percent charged. The transmitter is fully charged after three hours. Note: If you charge your transmitter in a charge-only base, you may need to re-

sync the transmitter with the base in your vehicle when you want use it again (see page 30). Charging in a vehicle with the ignition off When you shut down your vehicle, the DVR shuts down with it. Because the HiFi Mic base is connected to the vehicle through the DVR, the base shuts down as well. HiFi Microphone HiFi Microphone User Guide WGD00181, Revision A 31 HiFi Microphone After ten minutes, the base powers back up and begins to charge the transmitter. The base remains on for four hours to fully charge the transmitter, and then the base shuts down again until the vehicle, DVR, and base are powered on again. 32 HiFi Microphone HiFi Microphone User Guide WGD00181, Revision A Using Two HiFi Microphones Using Two HiFi Microphones For the most part, using two HiFi Microphones (HiFi Mics) in a vehicle is just like using one transmitter. When using two HiFi Mics in the same vehicle, do the following to minimize the potential for interference between the transmitters when both mics are in use:

l When you install the HiFi Mic antennas, install them horizontally in the upper-right and upper-left corners of the windshield to keep them as far apart as possible. l When only one of the two transmitters (mics) is in use, dock the unused transmitter in its vehicle base. HiFi Microphone HiFi Microphone User Guide WGD00181, Revision A 33 Best Practices and Troubleshooting Best Practices and Troubleshooting In this section... l Best practices for o Installing the HiFi Microphone (HiFi Mic) (page 35) o Using the HiFi Mic (page 35) l Troubleshooting HiFi Mic issues (page 36) HiFi Microphone HiFi Microphone User Guide WGD00181, Revision A 34 Best Practices and Troubleshooting Best Practices The items in the following sections are considered Motorola Solutions best practices. Note: These best practices are not required. They are provided to help you have the best experience possible with your HiFi Microphones (HiFi Mics). Installation best practices Keep the following best practices in mind when you install a HiFi Mic in your vehicle:

l Use a short cable (3-foot) when you connect the HiFi Mic base to the 4RE DVR; keeping the cable short helps maintain audio quality. l Use the antenna that you received from Motorola Solutions with the HiFi Mic. Using a different antenna can compromise wireless performance and audio quality. l l Install the antenna horizontally in the upper right-hand corner of the windshield (as you look out the windshield) and 2.5 inches away from the windshield's edge away from any metal. If you use two HiFi Mics in your vehicle, install the antennas horizontally in the upper right-hand and upper left-hand corners of the windshield to keep them as far apart as possible to minimize the potential for interference when two mics are in use. l Finger-tighten the SMA connector when you connect the antenna to the base. Using hand tools can damage the connector. Usage best practices Keep the following best practices in mind when you use your HiFi Mic:

l Power off the transmitter before you put it in the base to charge. l Avoid touching the charge and sync contacts on the base and transmitter with your bare hands. l If you have two HiFi Mics in your vehicle but you are only using one of them, dock the unused transmitter in its vehicle base. The unused empty base can interfere with the HiFi Mic that is being used. l Store the transmitter in a cool environment and with 40% or less of battery state of charge. 35 HiFi Microphone HiFi Microphone User Guide WGD00181, Revision A Troubleshooting Troubleshooting If your HiFi Microphone (HiFi Mic) is not functioning properly, refer to the sections below for possible remedies. If you have no reception... l Check that the power switch on the transmitter is on (see page 25). l Check that the transmitter battery is charged (see page 27). l Check the connection between the DVR and the base (see page 17). l Check that the transmitter and the base are synced, have a good connection, and that the transmitter has a strong signal from the base (see page 27). Tip: If your HiFi Mic still has no reception after trying all of the above steps, contact Motorola Solutions Customer Service for assistance. If you have poor reception, static, or noise... l Check the location of the antenna (see page 35). l Check the antenna connection on the base (see page 16). l Check that the transmitter and the base are synced, have a good connection, and that the transmitter has a strong signal from the base (see page 27). l If you have two HiFi Mics in the vehicle, check whether one of them is unused and NOT docked in its base (see page 33). Tip: If your HiFi Mic still has poor reception, static, or noise after trying all of the above steps, contact Motorola Solutions Customer Service for assistance. If the transmitter does not respond to or synchronize with the base... l Check that the base and transmitter have the Motorola Solutions branding to verify base and transmitter compatibility. l Check that the transmitter battery is charged (see page 27). l Check the connection between the DVR and the base (see page 17). l Check that the power switch on the transmitter is on (see page 25), turn it off and back on, and then try again to sync the transmitter and the base (see page 30).
