B45SWDUG5 V5.1 ‒ Swift Digital User & Installation Guide
Swift Digital
To charge a transmitter:
1. Switch off the transmitter and then plug in the charge lead.
2. Plug the charger into a mains socket and turn on the power.
When charging the Swift
TX
transmitter, the red charge indicator will light. A handheld
transmitter has no charging indicator.
The charge time from flat for the Swift
TX
transmitter is 10 hours and the other transmitters
16-20 hours. It is safe to leave on charge for up to 5 days.
Please note that it may take a few charge/discharge cycles before full capacity is available.
Transmitter battery charging
The batteries in all of these transmitters will last approximately 8 hours.
It is necessary to charge batteries before first use. For the Swift
TX
transmitter, fit the supplied
battery (see page 11) and connect to charger. The initial charge should take about 20 hours,
thereafter charge overnight as required.
You will usually need to leave the unit recharging at the end of the day.
To conserve power always remember to switch the transmitter off when not in use.
If a second transmitter is only occasionally used it will need charging less often!

Demonstrate and set the volume level for the room
It is important that the soundfield is set up properly. We have found
that some users set the system too loud. This is unnecessary and
undesirable. The golden rule is "if the user of the transmitter can
hear themselves very clearly from the Swift Digital, then the volume
is probably too loud". It is difficult for the person talking to judge
the level of their own amplified voice.
The usual way to set up an Swift Digital uses the subjective
judgement of another person. Two people are required with the class
tutor preferably being the one doing the talking.
Setting the correct volume level
l
Wear the microphone as shown.
l
Stand at the front (your usual position).
l
Switch the transmitter off and talk in a normal voice to your colleague
while they stand at arm’s length in front of you.
l
Ask your colleague to remember the average sound level and
then get them to walk over to the Swift Digital amplifier/speaker.
l
Switch the transmitter on.
l
Ask your colleague to increase the 'Mic A' volume control on the
amplifier, whilst you continue to talk in the same normal voice as
before, until they judge the sound level at arms
length from the Swift Digital to be just slightly louder
than when they were standing in front of you.
l
The tone controls can now be adjusted if necessary
to optimise vocal clarity.
l
Ask your colleague to make sure that your voice is
clear all around the room.
Job done! Don't be tempted to increase the volume
much further as teachers tend to raise their voices in an
active classroom situation!
Confidence
Please do not underestimate the importance of ensuring that the tutor has the opportunity to
experience listening to another person using the Swift Digital. There are two reasons for this:
firstly so that they become impressed at the natural sound and secondly it is hard for anyone
to listen objectively to their own voice. It is also an excellent opportunity to ‘play’ at using the
system with a colleague, allowing the tutor to gain confidence with their own ‘performance’.
If the system is to be used with a second microphone you must now go through the same
procedure using the ‘Mic B’ volume control.
