[. . . ] Insert the battery ensuring that the polarity of the terminals match those of the transmitter. The channel change switch (1) is located in the battery compartment, beneath the battery. 1 Press here to open A screwdriver operated rotary switch is easily accessible. If you do not get the channel working using the arrow end, it is worthwhile setting the other end to the required channel. All transmitters are supplied with an aerial (2) fitted. Should there be a need to replace the aerial it is a simple task to unscrew using a flat-bladed screwdriver of the correct size. [. . . ] DC input. Operation Check that all the items on the delivery note have been supplied, before you assemble your system. We have less sympathy with a claim that goods were not supplied after the hire has ended, than we have for a shortage reported at the beginning. In particular, note the number of tie clip microphones and their associated clips. Both can remain attached to costumes, and just vanish at the end of the show! Example of a flightcased kit. Bottom unit is an ADA, which allows all receivers to share a pair of Dipole aerials. It also powers itself and all receivers. Connect receivers to mixer inputs and attach all aerials. Single kits have their aerials attached, and these need only to be extended and set as shown in the cover picture. Multi-channel kits are supplied with 2 Dipole aerials that are connected to the ADA (Aerial Distribution Amplifier) and this supplies RF signals to all receivers. VHF aerials have a whip for the upper element, and a helical for the lower. Failure set aerials correctly can affect performance in a marked It is worth Failure toto set aerials correctly can affect performance markedly. It is spending time time experimenting with location, for a small small can often worth spending experimenting with aerial aerial location, for achange change can transform system performance. Where we have supplied a flightcased system, you should note that we number the transmitter, it's receiver and output cable with corresponding channel numbers. Power up using either plugtop power supplies (single kits) or connect to the mains and switch on the ADA (Aerial Distribution Amplifier) which in turn powers all the receivers in the flightcase. Connect the Microphone to each Pocket Pack transmitter in use. Always test multichannel systems with all transmitters switched on. Receivers lock onto the strong signals of their matching transmitters. In the abscence of such a signal they will accept unwanted interference (known as intermodulation interference - often shortened to `intermod' ), which can light several segments of the RF display. There is usually little or no audio present, but it can be confusing if displays light on channels you weren't expecting! CHECK - every performance Each channel in turn for RF signal strength and audio quality. Transmitter aerial for cable damage and ensure that the connector is tight. Re-set if required. Only when you are satisfied, should you distribute the transmitters. If you are not planning to use them immediately it may be best to switch off the transmitters. It is better to discover a problem at the end of a show, rather than 10 minutes before you need it next time!Handheld transmitters present fewer operational problems than do Pocket Packs. Stress to all users that they must take care until the transmitters are returned to you. [. . . ] Move each dipole aerial in turn checking the signal strengths on the RF displays for improvements. Check receiver aerials are vertical and with the [E] element at the bottom. Experiment with receiver aerial positions, while observing the RF displays on the receivers. Microphone crackles Screw-lock connectors need to have their locking ring tight. [. . . ]
