Slide the collet into place on the insert; make sure the alignment key on the collet
fits into the keyway on the insert.
Slide the shell into position; then slide the clamp over the collet and tighten. The
bus is held tightly against the cable by the clamping action; this assures a strong
mating of the cable and the connector. Ensure there is a secure electric connection
between the mic-cable shield and the bus wire attached to pin 4.
In Case of Difficulty
Most users of Vega equipment enjoy years of troublefree operation from their
wireless microphones. However, as with all electronic devices, problems may be
encountered eventually. If you experience difficulty with your Vega wireless
microphone within the first year of operation, it will be repaired under warranty
(see below.) Service for older units may also be obtained from Vega; contact the
factory or your sales representative for information.
The majority of difficulties with Vega wireless microphones are not due to
equipment failure. This equipment is fully tested before leaving the factory. In
most instances, problems are due to equipment application.
The following paragraphs describe the most commonly encountered application
problems. If you are having difficulties with Vega equipment, please review this
information and take any necessary corrective action prior to returning the
equipment for repair.
Battery
The most common problems with wireless microphones are those related to the
transmitter battery. Vega recommends that only new, fresh Duracell MN1604
alkaline batteries be used. Advertising claims notwithstanding, no other battery
tested by Vega provides equal life and equivalent reliability. Unfortunately,
batteries purchased in drug stores and supermarkets may not be fresh and
frequently do not yield rated life (4 to 6 hours is the usual range). Regular “9
volt” carbon cells have much shorter lifetimes (1 to 1.5 hours for a fresh unit,
perhaps less than one hour for a unit which has been on a rack for a year or so).
Cheap “bargain” cells may not work at all, since they often are really 7 volts
instead of 9 volts and may not be able to supply the required current.
Rechargeable cells (“ni-cads”) are often used in wireless transmitters. The units
commonly sold are almost always 7.2 volts instead of 9 volts and provide only a
few minutes of operation. The only acceptable rechargeable battery known to
Vega is the Varta, which is a true 9-volt design. Even here, the usable life will be
much less than for a Duracell (usually 1 to 1.5 hours.)
Battery contacts in the transmitter must be clean and unbroken. The battery
tension spring in the bodypack transmitter (opposite to the battery contacts) must
also be intact. Attempted forced reverse insertion of a battery is practically
impossible, but the attempt will often damage the tension spring or the battery
contacts. Damage to the springs or contacts usually requires a return to the
factory or authorized service center.
Exhausted batteries will cause numerous problems, including distortion, audible
squeals and howls, poor range, and off-frequency operation.
It is strongly recommended that the battery be checked prior to each use, and that
it be replaced if there is any question about its condition. It is also good practice
to try replacing the battery with a fresh unit when any problem with the wireless
