OPERATING INSTRUCTIONS S 910 / TS 910
Thank you for selecting the S 910 handheld or TS 910 beltpack transmitter. Please take some time to read carefully through this manual before setting up the equipment.
Important:
• When you unpack the product, inspect it for transport damage. If you do find transport damage, notify the transportation company without delay. Delay in reporting transport damage could result in the loss of your rights to compensation.

Safety Instructions

• Protect the transmitter from moisture and sudden impacts. You could either injure yourself or others or damage the transmitter.
• Do not blow into the microphone. In a condenser microphone this could damage the transformer. It is preferable to carry out a speech trial.
• Clip-on microphones are often very compact. If they are accidentally swallowed there is a risk of choking. Always keep this type of microphone away from small children.
• Always switch off the transmitter before charging or changing the battery.
• If the transmitter is fitted with a normal battery, never charge it in the charging unit. The transmitter or the batteries could be destroyed. There is a risk of explosion.
• The normal commercial 9 V alkaline batteries can have a length tolerance of 2 - 3 mm. When changing the battery always ensure good contact.
• From time to time the battery contacts should the moistened with spirits or alcohol and cleaned with a soft cloth.
• If the transmitter is not being used for weeks or months, please remove the batteries. Batteries can leak when not being used for a long time and corrode the conductor strips and components. Repair is not then possible. In this case all warranty claims are null and void. The description “leak proof” on batteries is no guarantee that they will not run out.
• Never take batteries apart yourself. The battery acid contained will damage skin and clothing.
• Do not throw used batteries into the domestic rubbish, but hand them in to local collection points.

2.3 Setting up

1. Push down the two snap locks on the right and left of the battery compartment and open it. Now you can adjust the GT/MT switch and the gain control .
2. Make sure that the transmitter and receiver are on the same frequency.
3. The LED of the TS 910 C will flash for a moment when the transmitter is switched on and indicates the normal battery status. When the LED fails to flash, there is no battery inserted, the battery is leaking or inserted incorrectly. The battery status of the TS 910 M can be seen in the LC-Display.
4. Connect the microphone or instrument to the input socket . Refer to illustration below.

2.4 Adjusting the input gain

1. Switch on the TS 910 beltpack transmitter with the ON/OFF switch. Turn the gain control fully anti-clockwise to minimum gain.
2. Speak into the microphone at the maximum level you expect to use. We recommend you use the letter “U” as a spoken “U” has a relatively good sine wave shape. Adjust the gain control to the desired gain. On the NE 911/912/914 receiver the AF level must not show any clipping. When miking instruments, play at the maximum level you expect to use.

4. Battery status

1. “ERR“ Message: When the “ERR“ message is displayed, there is an error. ERR noo3: The frequency you want to program is above the switching bandwidth of the transmitter. Use a receiver with an appropriate frequency group. (At this time the microphone is still operating and the frequency remains unchanged. To clear the displayed “ERR“ message switch off the handheld transmitter and on again.) ERR noo4: The frequency you want to program is below the switching bandwidth of the transmitter. Use a receiver with an appropriate frequency group. (At this time the microphone is still operating and the frequency remains unchanged. To clear the displayed “ERR“ message switch off the handheld transmitter and on again.)
2. “Group” & “Channel”: When both indications are displayed, it means that you are using the pre-programmed frequency of the receiver.
3. “Channel”: If “Channel“ is displayed only, it means that you are using a frequency which is not pre-programmed.
• When the battery is exhausted, “0%“ is displayed. When “PoFF“ is displayed, the transmitter is switched off, to avoid over-discharging the battery. Furthermore, the “Batt Low” LED of the TS 910 C beltpack transmitter will illuminate. Replace or recharge the battery.

5. How to switch off the transmitter

When the ON/OFF switch is switched to “OFF“, at first “PoFF“ is displayed and as soon as the transmitter is completey off the display is blank. Wait one second if you want to switch on the transmitter again immediately.

6. Battery change

• Switch the transmitter off before changing the battery.
• If you do not use the transmitter for several weeks or months, please remove the battery as it can leak after some time and damage parts of the transmitter. Even “leak proof” may leak after some time. Damage caused by leaking batteries is not covered under warranty.
• Clean the battery contacts from time to time by using a soft cloth moistened with spirits or alcohol.
• Please do not throw used battery packs away with your household rubbish, but take them to your local collection points.
• When using the S 910 C handheld transmitter or TS 910 C beltpack transmitter (fitted with TS 900 AP rechargeable battery pack) use the beyerdynamic SLG 900 charger only.

7. Before the soundcheck

1. Check the transmitter battery and replace or recharge it if necessary. Use fresh alkaline batteries only or recharge the rechargeable batteries inside the S 910 C handheld transmitter or TS 910 C beltpack transmitter (fitted with TS 900 AP).
2. When the transmitter is switched off and immediately switched on again, it is possible that the transmitter remains switched off. The cause is the function that allows to switch the transmitter on / off silently. Should this problem occur during operation, the battery might have contact problems. After switching off the transmitter you should wait at least 1 second, until you switch the transmitter on again.
3. Check the performance area for dropouts. If you find any dropouts, try to eliminate them by repositioning the antennae or the receiver.
4. The receiving antennas should be placed so that the distance between receiving antennae and transmitter is at least 3 m. If necessary, use remote antennae (AT 70 A/B).
8. Positioning of transmitters if interferences
occur
Put all transmitters in their position and switch them on. Switch each transmitter off one at a time and check the receiver for interference in the corresponding channel. The interference is possibly eliminated by changing the squelch. When using multi-channel-systems, please contact beyerdynamic. Interferences can also be caused by DVB-T television transmitters in the neighbourhood.

9. What to do to avoid feedback

Feedback is caused by your microphone getting too close to a loudspeaker.
We recommend:
• Move away from the loudspeaker.
• Turn the microphone away from the loudspeaker.

10. Trouble shooting

Problem Possible Cause Solution
No function • Transmitter and
receiver have different frequencies
• Insufficient battery voltage
• Poor battery contact, battery inserted incorrectly eingelegt
• Check if transmitter and receiver have the same frequency
• Replace the batteries or recharge them, if you use rechargeable batteries
• Check the battery and insert it again
No RF-indication at the receiver
•
Transmission distance between transmitter and receiver is too big
• Reduce the distance between transmitter and receiver
Noise/chirping •
Interference from other transmitters
• Two transmitters are on the same frequency
• Battery of the transmitter is too weak
• Switch off the other transmitters
• Change the frequency of one transmitter
• Replace the batteries

11. Service

In the unlikely event of equipment failure, the product should be returned to your beyerdynamic dealer. Unauthorised attempts at repair may invalidate the warranty.
12. Licensing
In most countries around the world, wireless systems must be approved for use by the authorities and it may be necessary to obtain a licence to use it legally. Your local beyerdynamic dealer will be able to give you details on wireless system regulations for your area.
The components of the Opus 910 system are approved according to the directive 99/5/EEC: TS 910 M, TS 910 C S 910 M, S 910 C
under the CE 0682 ! identification.
