The AC/DC Adaptor supplied will work with AC voltages from 100 to 240VAC. The Charger socket is located on the right-hand panel of your SuperBroom. It is recommended that the SuperBroom is left to charge for 6 hours to ensure a full charge. When connected to the AC/DC Adpator the Battery Charge Status LED on the front display panel is illuminated Red. When the battery is fully charged the front panel LED changes to Green.

This can, of course, make detection of ‘small’ targets more diffi cult. The battery packs have built-in protection circuitry and are designed to prevent reverse polarity connection.

- Page 11 SuperBroom Plus TA – Operating Manual Setting Up Setting Up It is recommended that users initially adopt the following search strategy. As experience is gained, users can develop their own techniques and methods. 1 Set the maximum legal transmitter power for country of operation at the set power menu during startup (UK = EU High). Note For non EU countries TX power is set using the rotary power output control (9). 2 Begin with the SuperBroom set to CLICK , COMPARE and Power mode (these are the default settings). Select DSP mode by pressing Listen. 3 Set the Volume control to minimum, set the Squelch control fully anticlockwise and connect the headphones. Adjust the volume control to suit (using the Test Target to generate a signal if necessary). The headphones are not needed at this stage so can be worn around the neck 4 Pass the Antenna Head over all surfaces in the search area so that, ideally, the distance between the antenna head and a potential concealment is minimised (for effi cient operation the minimum distance should not be less than 6 inches).
