Controls, Transceiver only:
•
The on/off/volume control activates and deactivates the headset, and it must be activated for
the transmission to work. This setup allows the headset to be turned off with the
on/off/volume button.
•
The transmitter channel (three channels are available) is selected with the button next to the
battery compartment. Select the same channel # for transmitting on the transceiver and for
receiving on the receiver headsets. Select another channel only if you experience interference.
•
To transmit: Depress the transmit button to put the transceiver in transmission mode. It
transmits continuously. This feature may be useful if the guide application described above.
When short communications are required, push the button to talk and push it again to end the
transmission. The microphone is noise activated, and will go into sleep mode if no voice is
heard for one minute. This is done to conserve battery life.
Battery life and replacement:
•
New batteries have to be installed when you receive the device.
•
The LED light next to the battery compartment will start to flash when the batteries have
about 20 minutes of life expectancy.
•
Batteries are located in the battery compartment in the ear cup w/o controls. Both headset
models use two AA batteries. Transceiver: In constant transmission mode the batteries will
last approximately 2 hours. When transmission is made only occasionally battery life is
extended significantly, and may exceed 10 hours. The transceiver is equipped with a voice
activated microphone, why the battery life will normally fall in the middle of the range, or 5-6
hours. Receiver: Battery life can be expected to be about 40 hours.
•
In order to replace the batteries, open the battery lid and remove the old batteries. Insert new
batteries, and observe that the polarization is correct, with the (+) on the batteries matching up
with the (+) on the battery housing. Replace the battery lid, and make sure that it locks in with
a distinctive snap.
Handheld microphone
•
The handheld microphone can transmit to both the transceiver and the receiver headsets.
Transmitting channels can be changed by removing the battery cover, and setting the channel
switch.
•
Unscrew the microphone base, in order to insert two AA batteries, making sure the
polarization is correct.
•
Battery life can be expected to be 2-4 hours when transmitting, depending on the situation.
•
The microphone can be used in a guide application, providing an avenue for visitors (using
receivers) to ask questions of the guide (using a transceiver).
•
Observe: The microphone cannot transmit simultaneously with the transceiver on the same
channel, since this will cause interference. The microphone can transmit to the transceivers
receiving channel while the transceiver is on. If the transceiver is used to guide a group, the
guide has to repeat the question to the group.
