How to Wear the Bodypack Transmitter:

Slide the transmitter clip onto the belt 1 or run a guitar strap through the transmitter clip 2 , as shown in the diagram at left.

Battery Replacement :

The life expectancy of two alkaline batteries is about six hours.

When the BATT indication symbol on the display screen is flashing as shown in the diagram below, the batteries should be replaced immediately, as shown in the diagram on the left.

TRC Receiver Setup:

Frequency Group No. and Channel No. selection:

Press “ SET ” key, and “ GROUP ” will flash. Press or key to select suitable frequency group number, as shown in Diagram 1 on the left. Then press “ SET ” key, and “ CHANNEL ” flashes. Press or key to select suitable channel, as shown in Diagram 2 on the left.

Note: when using several systems, you may set all the systems to the same group number, and then set a unique channel for each system in this group.

Receiver Volume Control:

This device features an electronic volume control system. Under the normal screen, press or key to control the output volume of the receiver

(there are 64 volume levels) as shown in Diagram 3 on the left.

Normal Display:

RF level, Audio Level, Group Number, Channel, and Frequency, as shown in Diagram 4 on the left.

Automatic Transmitter Frequency Setting (ASC):

HH64 Handheld Transmitter:

Point its IR window towards the IR window on the Receiver. Press the

“ ASC ” key on the Receiver. Verify the frequencies match.

MBP64 Bodypack Transmitter:

Point the IR window of the Bodypack Transmitter towards the IR window of the

Receiver. Press “ ASC ” key on the Receiver and then the “ ASC ” key of the Bodypack Transmitter. Verify the frequencies match.

Whenever the “ ASC ” key of the receiver is pressed, synchronizing signal will be transmitted continuously for 25 sec, and “ INFRARED ” symbol on the screen also flashes, as shown in Diagram 5 on the left.

When the infrared receiving circuit is enabled, “ INFRARED ” symbol on the Handheld Transmitter will flash and the entire display screen of the

Bodypack Transmitter will flash (the infrared transmission indicator lamp will also flash at the same time).

Notes: when establishing infrared connection between the receiver and the transmitter, the distance between them should not exceed 0.5m. When more than one system are used, only IR window of one transmitter should be pointed to the receiver for each infrared connection.

Transmitter Status Indications:

Battery voltage indication:

There are five battery voltage level indicators for the Handheld Transmitter, and there are six battery voltage level indicators for waist worn transmitter, as shown in Diagram 1 on the left.

Group Number and Channel Number Indication:

After the infrared connection between the receiver and the transmitter is completed, the same group number and channel as those of the receiver will be indicated on the Handheld transmitter, and the display screen of the Bodypack Transmitter will give a 5-sec steady indication of the Group and Channel Numbers, as shown in Diagram 2 on the left. Then it returns to normal status indications.

Normal Indications on the Display:

Battery voltage, group number and channel are displayed on the Handheld

Transmitter, and battery voltage and frequency are displayed on the

Bodypack Transmitter, as shown in Diagram 3 on the left.

Two TNC connecting cables (optional)

Two TNC connectors (optional)

Tips for improving System Performance

■

■

■

■

Maintain a line of sight between transmitter and antenna.

Avoid placing the receiver near metal surfaces or any digital equipment (CD players, computers, etc)

Keep the receiver away from the wall and at least 1m from the ground.

Cellular telephones and two-way radios can interfere with the operation of wireless systems.

Do not use these devices in close proximity to the wireless systems.

Troubleshooting
