4. EMENT The DTWS is drawing a low current all the time even when it is not switched on therefore your DTWS may be supplied without any batteries fitted To prevent damage to the DTWS always remove the batteries prior to storage Two C cells are required and may be nickel cadmium zinc oxide or alkaline which is the recommended type Ensure DTWS is switched off before removing batteries To fit the batteries to a DTW remove the end cap and then pivot the connector about the ribbon cable to allow access to the handle The batteries are fitted with the positive terminal first and are slid forward as far as they will go and then the connector is swivelled back and the end cap is then replaced and tightened To fit the batteries to a DTS remove the battery end cap and slide the batteries in with the positive terminal protruding Refit the end cap The DTWS can now be switched on and it may be set up for the correct operating modes If it is desired to switch it off then the SHIFT and ON keys should be pressed simultaneously Battery Disposal Issue 2 0 To be disposed of in an environmentally sound manner and in accordance with local legislation pm Do not incinerate Do not disassemble Do not short the terminals or expose to high temperatures Where the customer has issues disposing of the originally supplied batteries please return to Crane Electronics It is an offence to throw portable batteries out with domestic refuse DTS DTS W a
