clients in new installation, relocation or maintenance projects. Existing BS 6312 sockets before the handover are still in use and there is no compulsory replacement programme. Computers Keyboard layouts In the Crown colony, United States and Chinese (Traditional) keyboards were utilized by both the colonial Hong Kong Government and the public. United Kingdom layout keyboards are rare in computer malls in Sham Shui Po and Mong Kok. However, Japanese keyboards can occasionally be found. Regional settings in Microsoft products The default regional setting of Microsoft Windows sold in Hong Kong is "English (United States)". Many users in Hong Kong complain that their spell checker software highlights locally correct spelling like "colour" since they did not change the default regional settings in their operating systems and software applications. Most users, however, just leave the default regional setting (English (United States)) unchanged. Chinese versions of Microsoft Windows are far more popular than the English-language version among Chinese-speaking computer users in Hong Kong. Moreover, since many people use Chinese versions of Microsoft Windows and Microsoft Office to produce their webpages and emails, many English-language websites and emails In Hong Kong have the encoding "Chinese (Traditional)" (Big5) rather than "Western European" (ISO-8859-1). Unicode webpages are also not very common. Setting the browser to the encoding of "Western European" to view these Big5 Hong Kong webpages may cause some characters (for example, ',", £, € etc.) to be displayed incorrectly. TV broadcast Analogue terrestrial Hong Kong used the UK PAL-I broadcast system. Stereo audio is under NICAM system, which is the same as British standard. Digital terrestrial Hong Kong has adopted the system developed by PR China in 2006. DVD and VCD In the UK DVDs are region 2, of PAL standard. However, even though Hong Kong is under control of the People's Republic of China, DVDs found here are not Region 6 (for users in the Mainland China). Officially, the DVDs in Hong Kong are region 3 in NTSC colour-coding. DVDs of region 1 (US, NTSC format) or region 2 (Europe, PAL format) can be also found in local shops like HMV, which is not an issue for the local market as DVD players commonly sold in the shops are multi-region. Just as other Asian countries, VCDs are common for rental and sale in Hong Kong but these discs are not popular in the UK. Telecommunications Hong Kong uses the GSM 900 & 1800
