3.2.1 Transmitter (Fig. 4)

3.2.2 Headphones (Fig. 5) MERLIN 232

3.2.1 Transmitter (Fig. 4)

1.Open the battery compartment (8).

2.Remove the dead battery.

The battery is seated relatively firmly inside the battery compartment. The easiest way to remove the battery is to grasp it at the positive pole.

3.Insert the new battery into the battery compartment (8), making sure the positive end of the battery will point toward the connector (5). (If you insert the battery the other way round, the transmitter will not be powered.)

4.Close the battery compartment (8).

3.2.2 Headphones (Fig. 5)

1.Rotate the ear pad on the left-hand earphone through approximately 10° CCW to unlock the bayonet mount and remove the ear pad.

2.Remove the dead batteries.

3.Insert the new batteries aligning them with the polarity marks inside the battery compartments (12).

4.Replace the ear pad on the earphone and rotate the ear pad through approximately 10° CW to lock the ear pad.

3.3 Connecting the Transmitter (Fig. 6)

Note:

Do not connect the transmitter to a portable radio that uses the headphone cable as an antenna. Since the con- necting cable of the transmitter is very short, the receiver will be unable to receive a signal.

If you connect the transmitter to a personal stereo with an integrated radio, you can use the MERLIN 232 to listen to cassette tapes only.

1.Check what type of headphone output your audio source (portable stereo, DVD player, MD recorder, MP3 player, stereo system, TV set, computer, etc.) provides.

2.If your headphone output is a mini jack, you can connect the transmitter directly to it.

3.If the headphone output on your audio source is a 1/4" jack, plug the connector (5) on the transmitter into the supplied adapter (6). Plug the adapter (6) into the head- phone jack.

3.3.1Attaching the Transmitter to the Audio Source (Fig. 7) The supplied Velcro strips allow you to attach the transmitter to your audio source and remove it whenever you like.

1.Remove the backing from one of the Velcro strips and stick the Velcro strip on the transmitter rear panel.

2.Stick the other Velcro strip on your audio source.

3.4 Powering Up

1.Switch power to your audio source ON.

2.Set the OFF/FREQ selector (1) to "FREQ 1", "2", or "3" to switch power to the transmitter on and select one of three different carrier frequencies (refer to fig. 1).

The status LED (2) will be lit green for as long as audio sig- nal is present at the transmitter input. If no signal arrives at the transmitter input for about three minutes, the trans- mitter will switch off automatically and the status LED (2) will go out.

3.Set the three-stage INPUT LEVEL selector (3) on the trans- mitter to a position where the level meter LED (4) will flash green in step with the audio signal.

If the level meter LED (4) remains dark or flashes green only rarely, set INPUT LEVEL (3) to a higher setting or turn up the output level on your audio source.

If the level meter LED (4) illuminates in red, set INPUT LEVEL (3) to a lower setting or reduce the output level on your audio source.

4.Unfold the headphone arches, referring to fig. 8.

5.Press the on/off switch (10) to switch power to the head- phones ON. The status LED (11) will be lit green.

6.Press the AUTOTUNING switch (14) on the headphones. The Autotuning function will automatically tune the receiv- er to the carrier frequency set on the transmitter. After a few seconds, you should hear the signal in the head- phones clearly and free of interference.

If your first try fails, set the OFF/FREQ selector (1) on the

transmitter to a different position and press AUTOTUNING (14) again.

OFF/FREQ (1) lets you select one of three different carrier frequencies.

7.Set the VOLUME control (13) on the headphones to the desired volume level.

Note:

If the transmitter signal is disturbed, e.g., by reflections (multipath reception) or shadow effects, the headphones will automatically mute.

Note:

When the batteries are almost dead, reception will deteri- orate (increased noise). Charge the batteries.

3.4.1 Stationary Operation

You can also use the supplied charger to power the transmit- ter.

Refer to section 3.3.

1.Make sure a rechargeable battery is inserted in the trans- mitter and check that the battery is correctly aligned with the "+" and "-" marks inside the battery compartment.

If you insert no battery or insert the battery the wrong way, the transmitter will not be powered.
