1 Antenna Socket (BNC type 50 Ohms)
The antenna socket allows connection of the supplied rubber antenna or another suitable external or
plug-in scanner antenna. The supplied antenna provides good receiver performance over the whole
receiving frequency range. To attach the BNC antenna plug to the socket on the top of your scanner,
align the slots around the antenna plug with the tabs on the scanner's BNC socket. Then slide the
antenna plug down over the scanner's socket and rotate the antenna plug’s outer ring clockwise until
it locks into the position.
2. Connecting an Earphone/Headphone
This socket is for an external speaker or headphones. The internal speaker is disconnected
automatically if an external device will be plugged in.
Please note that you should not connect any headset or earphone with less than 32 Ohms, because
lower impedance headsets may be too loud when volume is turned too high. Please always start with
low volume before connecting any earphone. An external speaker should have at least 16 Ohms.
The plug should be MONO type with 3.5 mm diameter.
Warning!
If you connect an external speaker to the scanner's headphone jack, never connect a speaker which
has an external grounding. For technical reasons, any device connected there must be free of any
ground. A grounded device may damage the scanner.
3. ON OFF Power button
Press this knob about 2 seconds to switch the scanner on or off. A melody will sound and the LCD will
show the selected Band Plan System before receiving starts. The scanner always remember the last
used setting after switching on.
