2.3 Setting up

2.3.1 Powering

The TE 900 receiver is powered with 2 normal 1.5V batteries or rechargeable batteries of the AA-size. If you use conventional batteries, please use high-quality alkaline batteries. If you use rechargeable batteries, please use Ni-MH rechargeable batteries that are free from memory effect. If the TE 900 is powered with alkaline batteries, the operating time is approx. 10 hours. If the battery voltage drops below 2 volts, the power indicator (3) is illuminated red to indicate the decreasing capacity. If the battery voltage drops below 1.7 volts, the receiver is switched off automatically to avoid over-discharge or leakage.

2.3.2 How to replace the Batteries

1. Push down the two snap locks on the right and left hand side of the battery compartment and open it. Remove the batteries.
2. Insert two new 1.5 volt batteries (AA) into the battery compartment observing polarity markings. Then close the battery compartment again.

Important:

• If you do not use the receiver for several weeks or months, please remove the batteries as they can leak after some time and damage parts of the receiver. Even "leak proof" batteries may leak after some time. Damage caused by leaking batteries is not covered under warranty.
• Clean the battery contacts from time to time.
• Please do not throw used battery packs away with your household rubbish, but take them to your local collection points.
• When using rechargeable batteries use conventional chargers.

2.3.3 How to connect the Earphone

Connect the microphone to the mini stereo jack socket (2). You can use any conventional microphone or any other audio device.

Note:

Connect to the stereo jack socket (2) an earphone with stereo jack only. If you connect an earphone/headphone with mono jack, a short circuit can occur and damage the earphone/headphone.

2.3.4 How to switch on and adjust the Volume

To switch on the receiver turn the on/off switch (1) on top of the receiver clockwise. As soon as the receiver is switched on, the power indicator (3) will illuminate and the display (7) indicates the current channel. The channel indicator (7) goes out after 4 seconds to save power. To increase the volume continue turning the on/off switch (1) clockwise. To decrease the volume turn the on/off switch (1) anti-clockwise. The volume can be limited with the limiter switch (10).

How to switch on the Limiter

Note:

When the battery capacity is insufficient, the system cannot be switched on. Please replace the batteries immediately or check if the batteries have been inserted correctly.

2.3.5 How to select the Channel

Hold down the channel selector button (8) for two seconds. The numeric display (7) will start to flash. Release the channel selector button. If you press the channel selector button (8) once again, the channel number will be increased. When channel 16 is reached, it will cycle back to channel 1. When you hold down the channel selector button for two seconds while the LED is flashing, the channel number will be increased automatically, until the button is released.

2.3.6 Stereo/Mono Switch

The stereo/mono switch (9) allows the use of earphones with either a stereo or mono output. The transmitter must be set at stereo transmission, if a stereo output is required.

Note:

In the stereo mode the receiver features a richer sound quality, but with a lower S/N ratio. In the mono mode the S/N ratio is higher as in the stereo mode. This is why some users feel that the mono mode has a longer receiving distance than stereo mode.

2.3.7 Limiter Switch for Earphone

As the volume can be extremely high, the user should switch the limiter (10) always to the "ON" position.

Note:

To protect your hearing, it is recommended to set the limiter always to the "ON" position. To avoid damage to your hearing you should remove the earphone after using it for a long period of time.

2.3.8 Squelch

The squelch control (11) can be adjusted with a small screwdriver. If you turn the squelch control clockwise, the effective reception distance is reduced, but also possible interferences. If you turn the squelch control anti-clockwise, the effective reception distance is increased, but also possible interferences. For optimum performance proper adjustment is required.

2.3.9 RF Signal Indication

When the RF LED (4) is illuminated, it is indicating that signals are received from the transmitter. When interference signals occur, however, this LED will illuminate as well. To eliminate interferences, you should select an interference-free channel.

2.3.10 RF Receiving Antennae

The TE 900 receiver operates with true diversity. Therefore, two receiving antennae (12) are needed. For optimum reception do not shorten or tangle the antennae. Make sure that there is no material near the antennae that is conductive or that might interfere with reception.

2.3.11 Balance Control

With the balance control (5) you can adjust the volume balance of the earphone between the left and right channel. When turned clockwise, the volume of the right channel remains unchanged, while the volume of the left channel decreases. When turning anti-clockwise, the volume of the left channel remains unchanged, while the volume of the right channel decreases. For an evenly balanced volume level between the left and right channels, the control should be set to the centre position.

2.3.12 Belt Clip

The removable belt clip can be rotated 360^ . To remove the clip with a screwdriver rotate it 30^ to the right (clockwise).

3. Earphone (optional)

The earphones used for the TE 900 beltpack receiver can also be connected to other devices with a 3.5mm jack output such as CD players, MP3 players and laptops or PCs.

3.1 Connection to mobile Devices

1. Connect the earphone to the 3.5mm jack output.
2. Insert the earphones into your left and right ears.
3. Slowly increase the volume to a comfortable listening level.

Warning:
