• 3 orange LED which indicate the volume level of
sound received from the child unit. (4)
The LEDs: they progressively light up from the bot-
tom upwards indicating the sound volume level
NOTE. When the parent unit (primarily in receiver
mode) is switched on, it searches for the connec-
tion channel to the child unit (primarily in trans-
mitter mode) and the power indicator LED (5) will
blink until it establishes a connection with the
child unit (primarily in transmitter mode).
Warning.
When the parent unit (primarily in receiver mode)
is switched on, always check the operating status
of the child unit (primarily in transmitter mode)!
After switching on the units, always check that
the signal transmitted is actually received at
the distance and/or in the area the parent unit
is placed.
It is recommended to ask someone to help you
test the units; ask them to transmit from the child
unit (PT) whilst you move around the reception
area with the parent unit (PR) to check that the
signal is strong enough.
3. Replacing the batteries on the child unit
(primarily in transmitter mode) and recharge-
able batteries on the parent unit (primarily in
receiver mode)
Warning: these operations must only be
carried out by an adult.
- Only use alkaline batteries [child unit (primarily
in transmitter mode)] and rechargeable battery
packs [parent unit (primarily in receiver mode)]
equal or equivalent (with the same electrical char-
acteristics) to those indicated in this manual.
• Always remove the 1.5V tipo AAA alkaline bat-
teries (not included) and/or rechargeable batter-
ies when they are dead or you don't intend to use
the child unit and parent unit for a certain length
of time. This will prevent the batteries from leak-
ing liquid which will damage the devices and/or
anything in the vicinity.
- Do not short-circuit the battery poles.
• The use of rechargeable batteries on the child
unit is not recommended as the device func-
tions may not work as well. This child unit is not
designed for use with rechargeable batteries. Use
1.5V AAA alkaline batteries (not supplied)
NOTE. If the rechargeable batteries supplied for
use in the parent unit start to run down quickly
after charging, it will be necessary to replace
them (this is normal as all rechargeable batteries
run out over time)
• The rechargeable batteries supplied with the par-
ent unit must only be recharged using the mains
adaptor (1) supplied with the pack
- Do not attempt to recharge non-rechargeable
batteries as they might explode.
- This product is not designed for use with lithium
batteries.
WARNING Improper use could be haz-
ardous.
- Never leave dead batteries in the child unit (pri-
marily in transmitter mode), always replace them
immediately or they may leak corrosive and/or
hazardous liquids.
• Never leave rechargeable batteries in the parent
unit (primarily in receiver mode) when they have
run down; always recharge them immediately (or
replace if spent) as they may leak corrosive and/
or hazardous liquids.
• If the batteries happen to leak liquid, protect
your hands and replace the batteries immediately,
making sure you clean the compartment and any
other areas affected by the liquid beforehand.
Wash your hands thoroughly when you have fin-
ished. Dispose of all dead batteries according to
the differentiated waste collection regulations in
your area. Never burn them or disperse them in
the environment.

inserted with the poles in the right direction as
indicated on the battery compartment
- When inserting the NiMh 2x1.2V, 750 mAh type
AAA (included) rechargeable batteries in the
parent unit (primarily in received mode), always
