Telex RE-2 Transmitter On/Off Lock-Out, Using Multiple Wireless Systems, Battery Recommendations

Transmitter On/Off Lock-Out

There are two On/Off lockout modes available, One Time and Everytime.

One Time: Cycle the power switch 3 times in under 3 seconds and On-Loc will be displayed for a second and then return to normal operation. The power switch alone will no longer turn the unit off. To turn the unit off, put the power switch in the off position (On-Loc will be displayed) open the battery door and press [Set], [Up], or [Down] and the unit will power down. The next time the unit is powered on, the power switch will operate normally.

Everytime Use: With the unit on and operating in the normal mode, press and hold [Set], [Up], and [Down] for 3 seconds. On-Loc will be displayed and the power switch alone will no longer turn the unit off. To turn the unit off, put the power switch in the off position, (On-Loc will be displayed), open the battery door and press [Set], [Up], or [Down] and the unit will power down. The next time the unit is powered on, the On-loc function will still be on. To enable the power switch, press and hold [Set], [Up], and [Down] for 3 seconds (On-Off will be displayed).

Guidelines and Recommendations for Best Performance

Compatibility

The transmitter and receiver must be of the same frequency band and set to the same group and channel in order to work together. The RE-2 is available in two frequency bands, A and B. The band information is available in the Group/Channel edit screen on the receiver, the bottom label on the handheld transmitter, and on the back panel label on the bodypack.

Using Multiple Wireless Systems

If two or more RE-2 systems and/or other UHF/VHF wireless systems are being used in the same location, proper frequency coordination is necessary to avoid interference. All channels in the RE-2 factory set groups are designed to work together, so if channels from just one group are used no further coordination is required. Contact your dealer or Telex for as- sistance if you are planning more systems or using the RE-2 with other wireless equipment.

IMPORTANT NOTE: Always use the smallest preset group that meets your needs. For instance, if you want to set up 6 units, use one of the groups of 8 frequencies. The smaller the preset group, the more compatible the frequencies are.

Multiple Systems

and Advanced ClearScanTM

Because all of the channels in the factory set groups are com- patible, Advanced ClearScanTM can be used to set up multiple systems quickly and with confidence. When setting up more than one system, set up the first system using the ClearScanTM All function.

Once the working Group has been established, leave the first transmitter on, set the next receiver Group to the working Group and run ClearScanTM Group. This will provide the next clearest channel in that group. Set the transmitter to match, leave it on and repeat until all the systems are set up. If you run out of clear channels in one group but need to set up more systems, contact your dealer or Telex for assistance in choos- ing additional frequencies.

Potential Sources of Interference

There are many potential sources of interference for your wireless system. Any electronic product that contains digital circuitry including digital signal processors (reverb/multi-effects units), electronic keyboards, digital lighting controllers, CD and DVD players, and computers, all emit RF energy that can adversely affect the performance of your wireless system. It is always best to place the receiver as far away as possible from these devices to minimize potential problems.

Analog and Digital Television stations can also interfere with your wireless system. The RE-2 is designed to operate over 24 MHz of RF bandwidth, which covers four TV channels. The factory presets on the RE-2 are optimized for conditions where one or possibly two of the four stations are covered in your area. If three of the four stations are used in your area, it will severely limit the number of systems that will operate to- gether and you should be using a different band.

Battery Recommendations

Fresh 9-volt alkaline batteries form a quality manufacturer will yield the best performance from your RE-2 transmitters. Rechargeable 8.4-volt Ni-Cad batteries can be used but will result in much shorter operation time.

When the transmitters are turned on, the red battery LED will flash once if the battery is good. If the light does not light or stays lit continuously, the battery is weak or dead. If the light comes on during use, the battery is weakening and should be replaced as soon as possible. If sound quality degrades during use, it may be the result of a weakening battery.

Caution: The battery level indicators, on the transmitters and receiver displays, are based on the use of alkaline bat- teries. Use of other battery types will result in false read- ings on these indicators although the battery low LED on the transmitters will operate normally.

Receiver and Antenna Placement

Do not place the receiver near a large metal object or surface. Locate the receiver as close as possible to the area where the transmitter will be used. Ideally, position the receiver/antennas within sight of the transmitter. When using multiple systems, do not allow antennas to cross or touch each other. For best re- sults with multiple receivers, use an APD4 antenna splitter. (See Section 7).
