Note: Please take a note for frequency set at test mode.
CH70 frequency is set to 156.500MHz at test mode.
CH70 frequency is 156.525 originally. We changed this
frequency setting only for the test because there is possibility to
interfere DSC communication at your area when you conduct this
test longer time ( transmit longer time).
Receiving frequency is set to 156.525.
One of Japanese code less phone influenced DSC frequency recently
in Japan and the unit is recalled. Therefore, we arranged as above
for safety sake.
But, DSC Tx frequency is set to correct frequency (156.525MHz) for actual DSC transmission.
