Always  collect  the  transmitters  at  the  end  of  the  show.  Change  batteries  if
required,  and  conduct  your  checks  straight  away.    It  is  better  to  discover  a
problem at the end of a show, rather than 10 minutes before you need it next
time!

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. When
all are switched off you should check the receiver displays. It will soon be obvious if
you have missed one!

Handheld  transmitters  present  fewer  operational  problems  than  do  Pocket  Packs.
They are more likely to get dropped (or lost!). Stress to all users that they must take
care until the transmitters are returned to you.

Pocket Pack transmitters can be disguised quite easily with most costumes, but do
remember that aerials must be vertical.  We offer black microphones as standard, but
pink models are available if requested at the time of ordering.

Headband  microphones  are  available  (MKE48)  at  an  extra
cost.

NB2  adaptors  are  used  with  standard  microphones  (MKE2)
as  shown  in  the  illustration.  There  is  a  charge  for  these
adaptors.

Never stick aerials to skin

Capacitive  coupling  of  aerial  to  skin  (body)  leads  to  high  RF  absorbtion,  with  a
reduced  effective  output  to  the  receiver.  Avoid  placing  packs/aerials  next  to  the
skin. Sweat will always affect RF output.

  CHECK - every performance

Each channel in turn for RF signal strength and audio quality.
Inspect for damage to every microphone cable and connector.
Transmitter aerial for cable damage and ensure that the connector is tight.
Sensitivity (gain) switches get moved. Re-set if required.

Extra microphones are available should you wish to

  between different users.

We supply some spares with hires. Spare aerials and microphones are sealed and
clearly marked. They should only be used in the case of failure.
