1. A digital camera is a precision equipment, proper maintenance can extend its working life.

2. You should always clean up. You need to use external soft lint cloth, memory card slot of the battery should also be frequently with a soft brush or blow the balloon to clear the dust.

3. Digital camera battery generally have multi-coated lens to compare effemination, would accidentally scratch coating. Generally do not move it, it is necessary only need to be cleaned up, a little bit of dust, generally will not affect the imaging results. If we are not careful the camera on the left hand, it should be cleared as soon as possible because it is a damaged lens. Normally should be particularly careful to protect the lens and the surface of the lens with a very fragile, especially when gently wipe the correct way is: first blow balloon blowing dust, and then drawcircle professional lens cleaning paper, using the BG-E3 grip.

4. There will always be a digital camera with sophisticated electrical systems, more vulnerable, so to avoid high temperature, strong shock and drop from a height, do not suddenly from hot to cold outdoor room. What must be avoided water, fell into the water. Million accidentally soiled water, they should immediately turn off the power supply, wipe dry and then boot, in the case of the use of fog rain put a plastic bag and BG-E5 battery grip.

5. Kept a digital camera should avoid direct sunlight or high temperatures, but also to avoid a room on the wet. To stay away from dust, powder, sand and so on. Antimagnetic also, especially not on television, radio, refrigerators and other household electrical appliances. Long-term need to be taken out the battery Grip because the battery will be leakage, corrosion camera.

6. Although the digital camera is compact, easy to carry on the pocket, but it do not forget to wear a protective clothing ah, in case of multi-tap the touch ah distressed. You can use small Camera put it together, can also be fitted to other attachments nikon D40 battery grip, it is not very convenient?

Digital camera LCD screen is also the most likely to wash hands and clean have to be careful too, because in general there is a layer of LCD-plated anti-glare film, this coating has been damaged can not repair. Do not put pressure on, otherwise the screen will be damaged or malfunction.

7. The laptop battery stored in a dark dry place. The existence of the camera should also be dry, well-ventilated place. If long storage, can have the camera in a plastic bag with desiccant. Desiccant to absorb moisture will be lost after the results, to be replaced regularly and often to check out the camera, pressed the shutter a number of boot.

Notebook computer battery is the consumables, the battery once opened, will begin the process of aging. With the aging of the chemical characteristics of cells vary. Aging with the use of normal methods. If the frequent charge-discharge of BATCL50L batteries, it will accelerate the aging batteries. Battery life over a period of time, power will gradually shorten the time until the can not be used. Therefore shorten the battery life is a normal situation. Most of you who normally use an external power supply, like not using the travelmate 290 battery, but a matter of fact, the aging process of the battery over time has been less of the battery can only delay the process, but can not make it stop.

The impact of factors such as battery life:
Battery charge / release number of the use of the environment temperature (30 ℃ suggested that the use of temperatures below computer) battery storage temperature
Shock suffered by the size of the BATCL50L4 battery

Battery using must follow the below “principles”

1. AC Adapter (external power adapter) mode, use the battery if it has not gone through charge / discharge process, the life will be longer than the normal battery.

2. A smaller number of charge and discharge a certain extent, can extend aspire one battery life.

3. In the indoor temperature above 35 ℃, the battery wear and tear than the normal speed when the temperature much faster.

4. Throw, hit, etc. batteries will also accelerate Travelmate 290 battery depletion.

Application of the following battery will significantly shorten the working hours.

1. The use of CD-ROM drive, such as DVD, CDROM and CDRW drives.
2. The use of wireless communications equipment, an external PC card or USB device.
3. The use of high-brightness display settings laptop battery, 3D screen savers or other programs, such as 3D games.
4. In the highest performance mode of operation of the computer, power management program that is set to “always open” or “Max Battery mode.”
5. The activities of procedures, including procedures for running in the background.
6. LCD brightness (LCD more light, the greater the power consumption).
