27、mperature range of 0C to 40C (32F to 104F). If it is used in temperatures outside this range, an irregular display may appear. If it is used in temperatures lower than this range, the display may change very slowly. These irregularities will disappear and there will be no damage to the unit when it

28、is used in its recommended temperature range. Do not leave the unit in a location near heat sources, or in a place subject to direct sunlight, sand, excessive dust or mechanical shock. The nameplate indicating operating voltage, etc. is located on the rear exterior. Should any solid object or liquid

29、 fall into the unit, disconnect the AC power adaptor and remove the batteries, and have the unit checked by qualified personnel before operating it any further. Make sure that no liquid or foreign material enters the DC IN 4.5 V jack of the unit. This may lead to the malfunction of the unit. Since a
