4.3 Operation
The receiver only works when an earphone is connected
and the receiver switches to stand-by state. Push shortly
on the power switch button to switch on the receiver. The
channel number is shown on the LCD. The channel can
be changed with the channel selector. The channel
number is in accordance with the channel configuration
set up in the transmitter (see section 2.6.2).
When working, the battery icon and the antenna icon will
be displayed on the LCD to indicate the current battery
and signal status. A battery symbol “
” is visible on the
display when the batteries or the battery pack is almost
empty and needs recharging, but it still might work for 7-8
hours. When the signal is interrupted for a short time, the
receiver mutes the earphones output. If the IR receiver
does not get an adequate IR signal for more than 1
minute (e.g. when a delegate leaves the conference
room), the receiver switches to stand-by state
automatically.
The volume can be adjusted and displayed on the LCD.
To switch the receiver manually to stand-by mode, simply
press and hold the on/off button for more than 2 seconds.
If the earphone is disconnected, the receiver is switched
off automatically.
The infrared receivers are operable either with disposable
batteries (2xAA alkaline cells) or with a rechargeable
battery pack (HCS-5100BAT-16).
Install the batteries or the battery pack with the correct
polarity, as indicated in the battery compartment. A
separate connection cable is required if a battery pack is
used. The charging circuitry will not work if this cable is
missing, preventing thus also charging of disposable
batteries by mistake. The battery pack is equipped with a
temperature sensor to prevent overheating during
charging.
For more details about charging the battery pack please
refer to chapter 5.
Note:
When the receiver will not be used in a long
time, please take the batteries out to avoid
any
leakage or corrosion.
At the end of their technical lives both
disposable batteries and battery packs
should be discarded according to ecological
standards, preferably at your nearest
recycling station.
