Announcements to Tourist Group Members
Announcements via internal Microphone
Press Transmit button (PTT), talk into microphone (up to 20..30 cm distance is ok) und release button
after announcement. Other system’s typical disturbing squelch switching noise after releasing the PTT
button is eliminated by a special circuit. So it is not necessary to keep the transmit button longer
pressed than necessary. This saves battery energy and keeps the channel free when not used! During
transmit mode the LED will be red. In outdoor operation, you should consider to use the GHS 02
headset, if wind and environment noise should be too loud for the internal microphone.
Announcement with Headset Microphone
With Tour Guide headset GHS 02 inserted you
can either talk to your tourist group or you can
transmit a pre-recorded announcement from any
MP 3 player to the tourists. Plug the 4 pole plug
into the yellow marked Mic socket besides the
antenna. Press PTT button at headset control
unit to transmit. Only where necessary and
justified, you can also transmit longer time
continuously by shifting the transmit button into
the LOCK position (see photo). Do not forget to
release PTT button or to switch slide switch
back to PTT position after finishing the
announcement.
Transmission of pre-recorded Tourist
Information to the Group Members
Use the 3 pole plug for the MP 3 player. You can listen the recorded information via your headset. To
transmit this information, just press PTT button (or use lock slide switch). Simply adjust the MP 3 volume
at your player to obtain a convenient volume at your own headset. (We recommend to test for best
volume before use). You can also speak at the same time via your microphone to the tourist group! The
sound is automatically mixed.
Battery Charging
At every power-on procedure the tour guide can read the actual battery voltage in the display for a short
moment. (for example 3.8V means half charged, ~ 4 V is fully charged and ~3.4 V means nearly
discharged)
The charge socket DC IN is below the rubber cap on the right side. Here you can connect the supplied
USB charging cable. It is possible to re-charge the 1400 mAh Lithium Ion battery from any USB wall
adaptor or from any computer via USB socket. A totally discharged battery will need about 5-6 hours
charging time. Charging terminates automatically. During charging, you will see CHGING in the display.
