In the 2.4 GHz band, W52 and W58 can be used simultaneously because they do not interfere with each other. For example, it is possible to operate
detector No. 1 on 2.4 GHz (1CH above 5CH), detector No. 2 on W52 (36CH above 40CH), and detector No. 3 on W58 (149CH above 153CH) without
interference.
Support for the frequency bands usable under the regulations of each region and country is implemented by means of channel range codes, which are marked
on the detector.
The channel range codes of the main regions and countries, and their corresponding wireless bands, are listed below.
Channel range code
0x0001
0x0002
0x0003
0x0004
0x0005
0x0006
It is recommended that HT40 be used in the 5 GHz band because it is difficult to secure channels free of interference in the 2.4 GHz band.
The HT20 setting may be used to avoid interference with channels in the 2.4 GHz and 5 GHz bands. However, the transfer rate is inferior to that of HT40.
