The 220 Lite may be used with alkaline or
NiMH rechargeable PP3 batteries.
Fitting batteries
To fit a battery, slide open the battery cover, insert as
shown.
Although there is a battery polarity label in the 220 Lite,
between you and me you can actually fit the battery either
way around and it will still work!
The performance of the 220 Lite is the same whatever
type of battery is used. Note: the size of alkaline batteries
varies between manufacturers, Energiser batteries fit well,
do not force fit an oversize battery otherwise you will have
a problem removing it.
Developed especially for the domestic & social market, the single
channel 220 Lite combines the high sound quality, robustness
and value for money price
tag of the CRM-220; with the
primary concern of many
users – simplicity.
Straight-forward to use, the
220 Lite is an excellent
choice of entry level personal
fm radio aid for the domestic
& social user.

Step 2 Turning on
Check the channel number of the receiver, is it the
same channel as the transmitter?
Turn on the units by moving the toggle switch to the
left towards the middle. The battery low indicator
should give you a confidence wink.
When the battery charge becomes low, the indicator
will light and remain lit until the battery is changed.
1 The hearing aid user should listen at
arm’s length to somebody talking, to
establish the level of sound from the
hearing aid alone.
2 The hearing aid wearer should take
the receiver and place the neck loop
around their neck. They should then
turn their hearing aid(s) to the ‘T’
position.
3 The helper should take the 220 Lite
transmitterand walk to the other side
of the room while talking into the
microphone at 150mm (the length of
a biro) from the mouth.
4 The hearing aid user should be able
to hear the helper through the
220 Lite receiver by adjusting the
volume up to a comfortable level.
Congratulations, it’s as simple as that!

Step 4 Adjusting the tone control if necessary
Step 5 Connecting to a TV
The 220 Lite has automatic gain control to provide consistency of signal
level. The Connevans 220 Lite has a wide frequency response, with good low
frequency response and low distortion.
On the rear of the receiver are two very small ‘hidden’ tone adjust slider
switches (see illustration). One is a bass cut and the other a treble boost.
These tone controls allow you to match the sound through the radio aid
system to the sound of the hearing aid alone – simply choose the setting you
prefer. The easiest way to change these switches is to use the straightened
out end of an ordinary paperclip.
When used with an
inductive loop the loop is
worn around the neck for
use with post-aural
hearing aids. For direct
input hearing aids a wide
range of connection leads
are available – please
refer to our current price
list for an indication of the
available range.
A TV sound connecting lead is included in the pack. The preferred method
of connection is to use the TV AUDIO OUT connection – the 3.5mm jack
plug should be plugged into the socket on the side of the transmitter.
A SCART adaptor is
included for use when an
AUDIO OUT connection is
not available.
