Tone control
Change the frequency range/sound level and quality by changing treble/bass with by moving the control up or
down several times.
Battery
When the battery is fully charged it will last for approximately 8 hours' sound transmission. These times apply at
normal room temperature. A completely discharged battery will take about 4 hours to fully recharge.
The units have an inbuilt automatic charging mechanism that prevents the batteries from being overcharged or
damaged due to prolonged charging.
While charging is in progress the indicator will shine with a green light. When the battery is fully charged the
indicator light will go out.
The battery is permanently attached and can only be replaced at an authorised service centre.
Range
In normal environments the range will be approx. 5-50 metres. The range varies depending on whether the radio
waves transmitting the call are restricted by obstacles along the route.
Maximum range requires unobstructed transmission between the two units.
When using with a mobile phone the range of the mobile phone is limited to approximately 8 metres.
Make sure the antennas are extended for the best result.
