TRANSMITTERS

Operating the T2 Hand Held Microphone Transmitters

1. Press the POWER switch on the T88 receiver ON.

2. Slide the transmitter POWER ON/OFF switch to the ON position. Check the battery level. If the LOW BATTERY indicator is lit, see Transmitter Battery Installation.

3. Check the RF indicator on the T88 receiver to see if the radio signal is being received.

4. Slide the MIC ON/MUTE switch to the ON position and begin speaking or singing.

NOTE: If the red PEAK light on the receiver does not flicker during the loudest sounds, the transmitter gain may need to be increased. See the Transmitter Audio Gain Adjustment section.

5. During the performance or presentation, slide the MIC ON/ MUTE switch to the MUTE position when the microphone is not being used.

6. When the performance or presentation is over, slide the transmitter POWER ON/OFF switch to the OFF position to conserve battery power.

Squelch Adjustment

SQUELCH

DECREASE

FIGURE 5

The receiver squelch control is factory preset at the 12

o'clock position for optimum performance. No further adjustment is normally required. However, it is possible to adjust the

squelch control to emphasize either signal quality or system range.

• To raise the squelch threshold, rotate the control clockwise. This causes the receiver to demand a higher quality signal (less noise before muting), but it reduces the operating range.

• To lower the squelch threshold, rotate the control counterclockwise. This allows a lower quality signal through (more noise before muting), but it extends the operating range.

3. Insert a fresh 9V alkaline battery into the battery compartment as shown in Figure 7 (Alkaline recommended and included with the system). A fresh 9V alkaline battery should typically provide 18 hours of performance time. A fully charged 8.4V NiCad battery should provide 2 hours of performance time. When the LOW BATTERY light on the transmitter turns on, you have 1 hour or less of useful battery life remaining; change the battery at your first opportunity.

IMPORTANT: Carbon-zinc and zinc-chloride batteries will not provide adequate power and are not recommended.

4. Replace the battery cover.

Installing the Anti-Roll Device

The rubber anti-roll device prevents hand-held microphones from rolling off onto the ground when they are set down on a flat surface, such as a table or speaker cabinet. The anti-roll device proves an important safeguard in stage situations where the T2 may be used by inexperienced microphone handlers.

To install the anti-roll device, simply slip it over the microphone handle and slide it up so that it is positioned just below the label under the microphone grille, as shown in Figure 8.

FIGURE 9

The transmitter audio gain control has been factory preset to provide satisfactory output. However, if the PEAK light on the T88 receiver is constantly on or never on, the transmit audio level may require adjustment. Use the gain controls as follows to adjust the equipment for the best sound quality.

To adjust the audio gain, locate the transmitter audio gain control and use the supplied screwdriver to adjust the control.

• If the PEAK light is always on, decrease the audio gain by turning the gain control counter-clockwise (while the vocalist is singing or the musical instrument is being played) until the PEAK light on the receiver flickers only occasionally.

• If the PEAK light is never on, increase the audio gain by turning the gain control clockwise (while the vocalist is singing or the musical instrument is being played) until the PEAK light on the receiver flickers only occasionally.

NOTE: The T1 body-pack system is designed for use with

other equipment, such as lavalier microphones, guitars, headset microphones, etc. See your Shure dealer for details on ordering the proper equipment for your needs.

1. Clip the T1 body pack transmitter to your belt or guitar strap.

2. Connect the lavalier microphone, headset or instrument adapter cable to the body-pack transmitter.

3. Turn the transmitter POWER switch ON. Check Power/Battery fuel gauge.

4. Check the RF Signal Indicator on the T88 receiver to see if the RF signal is being received.

5. Slide the transmitter ON/MUTE switch to the ON position and begin speaking or playing your instrument.

NOTE: If the red PEAK light on the receiver does not flicker during the loudest sounds, the transmitter gain may need to be increased. See the Transmitter Audio Gain Adjustment section.

TIPS AND TROUBLESHOOTING

Tips for getting the best performance

• Maintain a line-of-sight between the transmitter and receiver antennas.

• Keep the receiver and antennas away from large metal objects.

• Avoid placing the receiver near computers or other RF generating equipment.

• Point the receiver antennas straight up.

• Avoid placing the receiver in the bottom of an equipment rack unless the antennas are remotely located.

Troubleshooting

Some common problems and their solutions are identified in the table below. If you are unable to solve a problem, contact your dealer.

Problem

No sound; RF light(s) not glowing.

No sound; RF and Audio Level meter lights glowing.

Received signal is noisy or contains extraneous sounds with transmitter on.

Noise from receiver with transmitter off.

Momentary loss of sound as transmitter is moved around performing area.

• Make sure the transmitter POWER switch is ON and the receiver is plugged into a power source.

• Check battery.

• Check receiver squelch setting.

• Check receiver antenna connection(s).

• Make sure antennas are in line of sight of transmitter.

• Turn up receiver audio VOLUME control.

• Check for proper connection between receiver and karaoke unit.

• Talk into microphone and observe receiver audio level lights. If they glow, the problem is elsewhere in the sound system.

• Check battery.

• Remove local sources of RF interference.

• If using a guitar or other instrument, check connections.

• Two transmitters may be operating on the same frequency. Locate and turn one off.

• Signal may be too weak. Reposition antennas. If possible, move them closer to transmitter.

• Adjust receiver squelch control.

• Remove local sources of RF interference.

• Reposition receiver or antennas.

• Reposition receiver and perform another “walkthrough” test and observe the RF indicators. If audio dropouts persist, mark these “dead spots” in performing area and avoid them during performance.
